Coway - Airmega AP-1512HH Mighty

My recommendation (had three in an apartment for eight years, they didn’t miss a beat) is the Coway Airmega AP-1512HH Mighty. Not cheap (~$200) but wait for a sale/coupon if you can. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

You’re going to want a Coway. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

Sorry, what "air quality problems"? Can't say we've noticed any, with our 3 air purifiers running 24/7 in a one-bedroom apartment... 😉 (Both of us have pollen allergies and one of us has asthma.) That should answer your question. Seriously, buy an air purifier. Once you feel the difference you'll probably end up getting a few more. We've got two of the medium Coway models (Airmega AP-1512HH or 200M) and a smaller BlueAir. They also help with smells -- bathroom, pet, or cooking. Highly recommend the Coways because they: * Are whisper-quiet on all but the highest setting, and can auto-adjust (though we usually leave them on medium because they get loud if they kick into high). * Move a lot of air for their size * Have filters that last way longer than they're rated for (as long as you clean the prefilter) * You can turn the main light on the purifier off for use in a bedroom at night Tip: it's better to get several medium air purifiers and put one in each room or area rather than getting just one big one.

I bought two air purifiers just last week after reading this sub! Coway 150 and ap-1512HH(W), they were on sale on Amazon.ca and I read somewhere I can use the carbon pellet filter from the AP-1512HHS in the non S version. So far so good!

The Coway Airmega AP-1512HH Mighty (or just Airmega Mighty), as per Wirecutter. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/ Wait for a sale. I got mine for £160 or so.

I see the Mighty recommended in multiple places and articles. Witecutter have chosen it as the best air purifier for a decade. That’s not the case with the model you mention. If you’re interested in that one for some reason then I would read plenty of reviews and compare it against the Mighty.

Anything Coway! I have a 240 and a 1512;both are great unit the 240 is alittle better and definitely quieter.

Coway Airmega AP-1512HH has been my go-to for a couple of years. It’s compact, quiet, and works like a charm for medium-sized rooms (up to 361 sq. ft.). The 4-stage filtration system (pre-filter, HEPA, carbon, and ionizer) is super effective at removing dust, allergens, and odors. I love that it has an eco mode to save energy when the air quality is good. It’s reliable and low-maintenance.

I have a Coway Airmega AP-1512HH Mighty that I brought to all my classrooms last year! There is definitely evidence that an air purifier can reduce illness in classrooms. And I tell my students not to come in if they’re sick! I think an air purifier is a great idea and an easy way to reduce illness. Hope everything goes well for you this year.

I second Coway. I have the [Coway Airmega AP-1512HH](https://www.reddit.com/r/ApplianceAdvice/comments/1cx5tt5/best_air_purifier_to_buy/) and it is a fantastic air purifier to improve indoor air quality. It's quiet, efficient, and has a sleek design that blends seamlessly into any room.

I have the coway airmega which is the wirecutter top pick (https://www.nytimes.com/wirecutter/reviews/best-air-purifier/) I liked it enough to buy a second one for my home. It has been great and it does make a difference.

Agreed on coway! They have a pet filter for two of their units too, the AP-1512HH and the 200M. It specifically tackles pet odor, dander and ammonia stuff in the air from pet waste.

I love the coway too! I have the Airmega Mighty AP-1512 HH and I've been using it with the intense smoke filter

I saw the Coway AP-3008FH in a client's office once, it looked HUGE so I would never consider getting it for my apartment. For 1000 square foot you could go for the Coway Mighty AP-1512HH. I have two units in my apt. Or if you want something that overcovers, you could check out the 350 or 450 for a big open space.

Conway Airmega 200M (or AP-1512HH, basically the same with different look) has been one of the most recommended for years. Not only are official filters likely to be available, there are tons of aftermarket options available as well. I don't really have power failures where I am, but I just pulled the cord for 30 seconds, and when it came back on it was still in the previous mode from before I pulled it. All the other options fit your critera pretty well. My only complaint is the blue air quality light on the top panel is brigher than I want in my bedroom, but I just put some tape over it. You can get LIGHTDIMS or similar to do the job and look good doing it. Those are highly reommended in general...

I don't know anything about that one. It uses a different filter set, but probably fine. If filter availability is a primary concern, the AP-1512HH or 200m are tops. If looks and performace are primary concerns, maybe check out rtings who is doing the best analytical testing at the moment and see if any of them float your boat. https://www.rtings.com/air-purifier/reviews/best/bedrooms

Coway AP-1512. My only complaint is that they lack a child lock button and my cats like to walk across the buttons and make changes. I’m looking into a whole home purifier for my HVAC system, though.

I've had a coway AP-1512HH running for years now. Works really well except that the fan speed modes are super quiet, quiet and ultra loud. I also do not like the blue led but just cover it. Big plus is that I can buy filters on Amazon for cheap. It was listed as best recommended at some as far as I remember.

Coway Airmega 350, Winix 5500-2 and Coway Airmega 1512.

Winix 5500-2 or Coway Airmega 1512

Winix 5500-2 or Coway Airmega ap-1512hh

Winix 5500-2 or 5510. Also Coway Airmega ap-1512hh

With the Winix yes. It has a feature called Plasmawave which you can turn off. Coway doesnt have any ozone. I have an 8 month old, and the Winix hasn't bothered her at all. We keep plasmawave on all the time.

This is my recommendation. We have a couple of these running on low all the time (we live on a busy street and they’re nice to have for our fire season).

We have the airmega that [looks like an iPod](https://a.co/d/8WCcJ0z) and love it. It goes on sale every once in a while, I think.

I tried a few of those models at home, and the Coway AP-1512HH has been the one I’ve stuck with.

The Coway Mighty - we liked it so much we ended up with another one for our second floor. [Amazon Link](https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-White/dp/B01728NLRG/ref=sr_1_1_sspa?crid=33NJV6SWPTL6M&dib=eyJ2IjoiMSJ9.2_UoO6pldtX_1sj-QWLF_TYhrn1dCOd7A20FRyCF6sTGt5ZH6VYrhuR84pQqT8duXMwP5eX99ov09c1mQRIBnk0WnBsJiDkrK-SY1A_Hk0dIbXri4i_GmGlbPsrW1RPVAYGNdXhxnaj2HoffEGrg5aw5LbYAmTy0FUmv39XYC_bK-JqDQvH7LOjOfBy29HEArtGk-X848-HAzMQTHrGRoGQPqgShAtD1DFpqvKPAl44.CmqTVQo6zbBJGXkly_zus7Q6Byu-AAHWu19cerhu6CU&dib_tag=se&keywords=coway%2Bmighty%2Bair%2Bpurifier&qid=1747862431&sprefix=coway%2Bmight%2Caps%2C151&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1)

I just bought the coway airmega ap-1512hh. It was wirecutter’s pick, the amazon reviews were positive, done. I have a new apartment so been buying quite a bit and couldn’t be bothered to go down a rabbit hole of comparing fifteen different products. It’s working well. I do wish it was WiFi enabled. But I bought it for pretty much the same purpose, improving the room smell as I have a very elderly rabbit who no longer uses his litter box. They have a special pet filter but I decided to try out the one it came with for a few days and see if I felt it was necessary - it wasn’t. I don’t think any one air purifier can do the whole house unless it’s attached to your HVAC system. I’m probably going to get another one for the bedroom.

I'm also liking Coway. I got 3 of the 1512hh for the bedrooms and so far I'm linking them. Then I got the blueair 211i max and realized that the fabric is the pre-filter. I'm in Los Angeles so I got it because of the wildfires and possible asbestos but I'll be returning it because of this design. I didn't it try at, just took it out, saw how it's all attached together and tomorrow I'll send it back. Waste of time. I now got a Coway mega 1216l I hope it works better, it was only $100

The normal everyday mode is not loud. But if you forget to turn the fan on while you brown meat and your whole house is filled with smoke the unit will kick on and be VERY loud for several hours (depending on size of your space).

Ya it has an auto mode that will turn the settings up or down depending on what it’s sensing in the air.

The Coway AP-1512 (and the Coway Airmega 200, which is almost the same thing) are still good picks, as is the Winix 5500-2. All three have similar performances, including cleaning airborne viruses. I would also look at the Levoit Vital series, and the new PC fan filters like AirFanta and CleanAirKits. [https://www.nytimes.com/wirecutter/reviews/best-air-purifier/](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/)

The Coway 150 or the Winix C545, with some caveats. But I recommend upgrading from the Coway 150 to the Coway Airmega 200 (which I have) or Coway Mighty (a little harder to clean the front panel of the Mighty than the Coway 200) to provide flexibility of moving it to a larger room. Depending on the merchant, the 200 isn't much more expensive than the 150. [Wirecutter](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/#our-pick-coway-airmega-ap-1512hh-mighty) rates the Winix C535 as performing as well as the Winix 5500-2, so presumably the Winix C545 would be good. I don't recommend the Winix 5500-2 (which I also have) for ***bedrooms*** because you can't turn off the annoying display light--not good for sleeping. But I consider the 5200-2 to be better than the aforementioned Coways only because of its charcoal filter with charcoal pellets--not the charcoal filter pad that the Coways use. Also, it's easy to forget to turn off 5500-2's pointless "PlasmaWave" feature when you turn on the machine--probably not good to have that activated in your baby's room. Other than that, Winix 5500-2 and the Coway Airmega 200 have the same specs (airflow and coverage). I don't know if the Winix C535 and the C545 lack a light shut off feature similar to the Winix 5500-2's lack of that feature. Levoit Core 300 seems ok but it has some quirks mentioned in this video of the Levoit Core 400: [https://youtu.be/h-keLXkIKI0](https://youtu.be/h-keLXkIKI0) (I like that guy's reviews of air purifies--he really knows what he's talking about. And he rates the 5500-2 as the best one on the market). An air filtration expert did all types of tests on the Levoit Core 400 and the results were impressive. I don't know anything about the Smart Air Sqair. But I notice that unlike the Levoit Core 300 and seemingly all Winix models, the Smart Air Sqair doesn't have an AHAM Verifide certificate (to be fair, neither does any Coway model). [https://www.ahamdir.com/room-air-cleaners/](https://www.ahamdir.com/room-air-cleaners/) Smart Air Sqair also doesn't specify what its clean air delivery rate (CADR) applies to--smoke, dust, or pollen (smoke is always the lowest of the 3)--which to me is red flag on honesty/openness. What's the height of your ceiling?

Yes. It looks like the C545, like the Coways, uses a charcoal filter pad, unlike the 5500-2's better charcoal pellet filter. The Winix 5500-2 is much more equivalent to the Coway Mighty/200 in terms of capes. Do you mean they're roughly equivalent in terms of noise?

You’ll typically see the same top-rated models across Wirecutter, Consumer Reports, and Tech Gear Lab: the BlueAir Blue Pure 311i+ Max, Coway Airmega 1512HH, and Winix 5500. The best choice probably depends on the size of the space you’re trying to cover. For my downstairs rooms, I went with two BlueAir units (the 311 and 211 models). BlueAir offers a 25% discount for teachers, military, police, and possibly firefighters (can’t recall for sure), available in both the U.S. and Canada. They also offer a 15% discount on filter replacements if you sign up for a 6-, 9-, or 12-month subscription. For my upstairs office/bedroom—since it’s a smaller space—I went with the Coway Airmega 1512HH and have been happy with it.

I have been using the [Coway AirMega](https://amzn.to/49gjTgt) for years. It has also been [Wirecutter’s](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/) top pick for a long time.

These worked very well for me when my area was inundated with smoke. My house is old and porous, so it was fairly smoky inside without them. I started with one that I would move with me from room to room. I now have 3 plus one smaller model. Edit: Coway has another model that is exactly the same but with a nicer looking front plate. I think it might be the 200?? I don’t know for sure. It takes the exact same filters as the 1512.

Coway is regarded pretty highly I just bought an airmega 400 but something like the airmega 1512 has been a top performer in its class and it's on a sale RN for 165.

AirMega is better imo for bedroom.... 1512 lights up the room at night.

I’ve tried a few of the ones you mentioned, and the Coway AP-1512HH has been my favorite for years.

We have two Coway Airmegas and they have worked pretty well, I like to sweep up my dirt and cat hair in front of them...we still never bought a third, our house is rather large and I like one in the bedroom. https://a.co/d/2AZzVUv

I have the 200m. I'm sure the 1512 would also. And prob higher models

COWAY makes a great product.

I have two of these https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-True/dp/B00BTKAPUU Other retailers have them too. I bought one with a 30% off coupon at Kohl’s years ago

I have that one, too. It looks decent, it's quiet, and it does what it's supposed to.

I had my eye on the HATHASPACE HSP003 but found its app alerts too jarring, so I swapped it for the Coway AP‑1512HH.

I use the [Coway Airmega AP-1512HH Mighty](https://www.nytimes.com/wirecutter/out/link/7595/150104/4/110485/?merchant=Amazon) for my Grey. No issues so far. [https://www.nytimes.com/wirecutter/reviews/best-air-purifier/](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/)

I have an embarrassing, funny story about this model. Bought it last year for my edit suite. It gets pretty dusty. Been running it every day since. Told my wife, "see? Much cleaner air" Secretly, was always a little disappointed about how dusty it still was... And also, on the highest setting, it would rattle and walk across the room. But okay, it's well reviewed. Going to see it through. Went to change the filters for the first time last month... They were still wrapped in the original plastic inside the machine once I took the cover off 🤦🏻‍♂️ Moral of the story: open it up and remove the covers from the filters the first time you use it. House is a lot less dusty these past few weeks.

Coway Airmega AP-1512. This thing goes nonstop, is quiet, and does a great job. Inexpensive to run as well. ~$170

I highly recommend the Coway Airmega AP-1512HH, it’s currently on sale for $210 on Amazon. I’ve been using it for a few months now and it’s definitely the best I’ve used. It also has different filter kits for different uses (standard, allergen, smoke, and pet).

I have the Coway and it’s pretty solid. To be totally honest though I didn’t notice that much of a difference in the dander and hair until I started vacuuming every day and deep cleaning frequently. Top to bottom, floors. For the hair floating around, there isn’t going to really be an air purifier that will suck all of that up. You just have to spend a ton of time cleaning, regularly.

The Coway I'm using has an Intense Smoke carbon filter certified for removing harmful VOCs which that wouldn't do. [https://cowaymega.com/products/airmega-200m-ap-1512hh-filter-set?variant=45617013522686&selling\_plan=4003627262](https://cowaymega.com/products/airmega-200m-ap-1512hh-filter-set?variant=45617013522686&selling_plan=4003627262) Edit: Plus I'm able to use this in the place where I am staying while we're evacuated.

Even with a replaced HEPA cabin filter, this is better.

I have a Coway AP1512. One day I’ll get an air mega. I live in ~500 sq ft apartment with two cats. I keep it in my living room near where their litter area is (hall). It takes up so much dust and hair it’s wild. I can tell it works because it’s light sensor goes off when I put on perfume or baby powder in the bathroom, which is well away from where the filter is, or when I fry or bake anything. It’s really sensitive. That plus keeping the windows closed on smoke days has been a game changer!

I’ve got a Coway 300S in the main living area of my house (kitchen, dining room, living room), and a Coway 1512 in my bedroom. Both have been great! Highly recommend Coway.

We have a Coway Airmega AP-1512HH Mighty on each floor of the house ($170). It makes a huge difference, in my opinion, to eliminate odors so I’d imagine it’s removing other things I can’t see as well. I loaned it to a friend during a home renovation and it was great for removing construction dust too. I let them run on power saving mode 24/7 and bump up the kitchen one if I’m cooking something fragrant or using the gas stove/oven.

My recommendation for price/performance USED to be the Taotronics TT-AP003, but unfortunately, it looks like it was discontinued :( All units with HEPA filters have basically the same filter, so don't overthink it. However, the ONE SPEC that matters is [CADR (Clean Air Delivery Rate)](https://en.wikipedia.org/wiki/Clean_air_delivery_rate) - this measures how MUCH air it filters. Manufacturers don't like to advertise this unless it's good - likely because their smaller/worse air purifiers wouldn't sell as well! Also note that the advertised CADR is only at the highest (aka *loudest*) fan speed. *For less noise, it's better to get a larger filter and run it at a lower speed - you don't want a little hurricane in your bedroom all night!* Here's some commonly recommended filters (and some from this reddit thread): * The [Levoit Core 300](https://levoit.com/collections/air-purifiers/products/core300-air-purifier) has a CADR of 135 CFM for $99. * The more expensive [Levoit Core 400S](https://levoit.com/products/core-400s-smart-true-hepa-air-purifier) has a CADR of 260 CFM for $219. * The Wirecutter-recommended [Coway Airmega AP-1512HH](https://cowaymega.com/products/mighty-ap-1512hh?) has a CADR of 232+ CFM for $168 (price as of today) - not a bad deal! * The [Winix C909](https://www.costco.com/winix-c909-4-stage-air-purifier-with-wi-fi-%2526-plasmawave-technology.product.100842491.html) has a CADR of 323+ CFM for $199 (Costco online price). Also seems like a good value. * The [Winix C610](https://www.costco.com/winix-c610-4-stage-true-hepa-air-purifier-with-wi-fi-and-additional-filter.product.4000295784.html) has a CADR of 245 for only $129 (Costco online price)! **Probably my recommendation for best price/performance for small/medium rooms.** * The expensive [Dyson HP7](https://www.amazon.com/Dyson-HP07-Purifying-Heater-White/dp/B09LSMRKFD) bladeless heated fan and filter only has a CADR of 80 CFM for $599 (!) You'll notice that filters of similar size have similar CADR. That's because they're essentially a HEPA filter and a fan - it's hard to improve filtration without a larger fan or larger filter. The differences come down to noise level, build quality / customer support, features, and cost of replacement filters. Cheers!

I recommend getting Coway but having one for each room. The Coway Airmega AP-1512HH is really good and there are good prices for new units on eBay - I just got one there recently. It’s not very loud and actually the noise is not too bad compared to Levoit & I have extreme noise sensitivity issues.

I had it and replaced it with the Coway. The Coway is a beast compared to it, it is much better.

Like others, I swear by the Coway Airmega, but that’s just brand/model loyalty. You’ll want you check each model’s CADR score - the higher the number, the faster the unit filters the air. Decide what your ideal budget is, and find the unit with the highest CADR at that price point.

Coway Airmega 1512. I’ve bought several of these for myself as well as friends/family. It’s been #1 on Wirecutter several years in a row. It should be $200-300 on Amazon - wait for a sale as it goes down to $200 often. Second choice would be Clorox medium room. FWIW, I’m an air quality scientist.

Coway 1512hh is a constant top pick & sounds like a jet engine on high. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

I have 2 of these. One of them has been running nonstop for 5 years and still is perfect. It's astonishing what it pulls out of the air!

The Coway ap-1512 is probably cheapest one worth buying, IMHO. You should also think about running cost - keeping filters reasonably fresh. Generic Coway filters are readily available and good quality, plus it’s energy efficient and quiet.

I’ve got one of these and the Coway Airmega 1512HH as recommended in another comment. Both work very well, but the Winix makes noise on all speed settings, while the Coway is silent on low, near-silent on medium, and makes a much more pleasant air rushing sound on high than the Winix.

It can be turned off easily.

I have three too. They've run 24/7 for years without an issue. Third party filters work fine and are half the price.

I have three Coway Mightys. Run them 24/7 for years. Nearly silent, trouble free, and third party filters (tested for effectiveness) cost $20 a year.

Probably the Mighty, AP-1512HH. I have three, and they're great. They've run 24/7 for maybe five years now. It happens to be on sale right now. The Coway 200M is identical (and uses the same filters) except for appearance. It's even cheaper right now. Third party filters from Cabiclean and Durabasics are cheaper and in tests, work just as well as Coway filters.

The Coway Mighty that everybody loves can handle that size room if there's no open windows, air vents, etc. And on medium it's whisper quiet. I don't even notice it, and I have three.

I have a cat with asthma! I got two of the coway airmegas and they work great. In a one bedroom apartment. The asthma attacks went way down

i have two of the coway airmega ap-1512hh. i think it has an optional ionizing function which i leave off. read it basically does nothing either way. but i highly recommend the model! also great for smells

Coway Airmega AP-1512HH Got 2 of these last year. Mold, mildew, cats, dust. I have allergies and asthma. My rescue inhalers now last months instead of weeks.

https://www.amazon.com/dp/B01728NLRG/ Conway Airmega 1512 Been running 2 of these in a dusty old house with a moldy basement and a4 legged shedbeast. Rescue inhaler usage has gone from "maybe the next one will last all month" to "I don't remember what season I opened this one". Was Wirecutter's top pick. Lowest setting is silent yet still moves a lot of air.

Good thing these don't have software, then.

I feel for you, OP. I am an allergic-to-everything person to the point that I've needed to move homes to get away from paint, varnished wood, carpet, etc. The biggest trigger for me, though, and maybe for you is any centralized heating and cooling system. The systems' filters don't matter - the room's unfiltered air is also being blown in your face. I haven't found a purifier that can offset this problem. I don't use ACs and all my heat is water-based or electric. I experimented with Dyson - if it's the model that provides heating or cooling, there is a chemical in the device that can cause reactions. You can also be sensitive to the material in any carbon filter, like coal. The imperfect journey continues, but I ended up getting a custom purifer from Aller Air and I use it in the same room as a Coway HEPA. One for gas and chemicals, one for particulates. It still doesn't save me completely from my dusty old building, but I can now be confident that it's the only issue. Good luck!

I also have two of the Coway Airmega AP-1512HH and they work great! Easy to clean and replace filters.

I have six of these in my house, would recommend. Only thing to be aware of is the filter replacement cost each year.

I have the ones you linked. I got the model number wrong in my earlier post.

I was going to suggest, like many top contributors here do, getting one purifier per floor and one for the bedroom — I had three AP-1512HHs in mind. But since you mentioned setting up a wedding registry, you might consider going with two Airmega 250S units and one Airmega 350 instead. Congratulations on your wedding, by the way!

It's a good purifier and moves a lot of air. It's not the most energy efficient or cost effective large filter out there, though. Multiple smaller filters may cost less and perform better together due to better air mixing. I've also noticed that it winds up with less large or lint-type dust and hair, including cat hair, on the pre-filter than the multiple Coway 1512HH that we keep in other rooms and that we used to have in the same double room where the 400 is now. I think this is because of lower face velocity of the air, due to the 2x filter surface area (which on the plus side lowers resistance, increases energy efficiency and filter life, and decreases noise). And potentially also because it's higher off the floor. It may not be trapping all the heaviest particles, which would settle to the floor eventually in any case. It's a good idea to vacuum regularly because of that (and in any case). Some things to help you with your decision. If you do go with it, try to find a sale because they're often steeply discounted.

[Coway Airmega AP-1512HH](https://cowaymega.com/products/mighty-ap-1512hh) is the standard recommendation. If you live in a normal 1 bedroom apartment, it's good enough to clean the main living space, e.g. kitchen + living room, but you'll probably need a second one for the bedroom. Also, it's generally better to get multiple smaller purifiers (one for each room) than one large purifier. I had two Airmegas for my 2-bedroom apartment, one for my kitchen/living room and one for my bedroom that I sometimes moved to the office. If you don't care about aesthetics you can also build your own by taping HEPA filters to a box fan: https://cleanaircrew.org/box-fan-filters/ You don't get the smart air quality detector of the Airmega, but you save quite a bit. Air purifiers aren't that fancy, so don't overpay. Even the Airmega at $200 might be overpriced; I got both of mine for $150 each on sale.

Came here to say the same thing, the AP1512HH is amazing. And you can use third party filters and save money that way.

We have three of the same purifiers in our house and love them!

IMO they’re not that expensive. I get replacement ones for $40 on amazon and they last me a year. It comes with 2 outer layer replacements (that are changed 2x a year) and one inner layer replacement that’s changed 1x a year.

Same here! Got one for each room last year, and very satisfied with it so far.

Second the Coway Airmega! It is a beast, honestly. I’ve had it in my bedroom for over a year now, and you can literally feel the difference in air quality. 

I bought the AP-1512HH, same as the comment at the top.

I bought the coway airmega last year and love it ever since. The filter is really easy to change and it runs pretty quietly on low settings.

Tried Winix for the affordability and great reviews. Trashed within the year, Co-way outperformed it by far. 

I’ve used a few of those you listed, and the Coway AP-1512HH is still my favorite overall.

Amazon has some black Friday cyber Monday deals. I just picked up the coway 1512hh for my son's room, and a winix 5500-2 for the kitchen. Both on sale are under 300 all together. I'd recommend those for a bedroom and or living area depending on size of the rooms. I believe the coway has a pet filter optional you can purchase which may or may not help more. Ideally you'd want 4 air changes per hour or more in each room you'll mostly be in with the pets. There are calculators to help you understand

I wanted a shorter height purifier for my son's room. And have been interested in coway. I also decided to get the 1512 as I read you can swap in the carbon pellet filters with some modification that they offer for the 1512hhs. Also, I put the coway in my son's room as it's sensors are more focused on particulate matter. Whereas the winix also has odor and gas sensors iirc which would be better suited for the kitchen. Interesting note is all 3 are highly regarded South Korean companies.

I’ve used a few purifiers in that range, and the Coway AP-1512HH has been my favorite.

I have 5 Coway Airmega’s. 1x Airmega 250 3x AP-1512’s 1x Airmega 100 They are BY FAR the best I’ve ever had and I recommend them to everyone. There was a very thorough test video done by wire cutter that originally piqued my interest here: https://youtu.be/VM9CJZpqfpA?si=s45QTvHQnlvtbcDE

It's not mysterious technology or snake oil. Air filtration is well understood. They definitely remove particulates from the air. I have a few HEPA filters around the house -- relatively basic ones -- Coway brand. Each was like $150 and the filters are a $15 replacement once a year. They're quiet and have nice auto/eco settings and even a sensor. The sensors obviously work because they ramp up a when we cook or otherwise kick up dust. I guess the question is -- does it really matter? The official verdict is still out on that, I guess. But I think it probably does. I don't *feel* a difference, but we live in a metro area where there's plenty of particulate around that's known to be harmful like tire & brake dust, so I think it's worth it over the long term especially with kids. Incidentally I remember reading that HEPA filters do in fact filter out airborne pathogens. There's part of me that is convinced that if we had decent HEPA filtration in public spaces, we'd see a marked drop in flu, RSV, and things like that. But who knows.

That’s interesting. I’m extremely sensitive to smells but I’ve never noticed a smell with any of my coways, I have 5 of them. Absolutely love them/

I have asthma and it’s helped with that. It tends to get triggered with smells and such. I will say this. I have allergies to mold. My air purifier for months was red and I figured the light was broken because I wasn’t experiencing any symptoms (no sneezing, runny nose, watery eyes) and I’m allergic to everything. Then we discovered mold on a shelf. Threw out the shelf, air purifier turned blue and no more issues. So it was definitely doing its job!

lol. I was so mad too because my new purifier was broken 🤣 glad it was actually just working

Thirding this one, we have a few and like 'em.

I'm so sorry about your kitten! My kitten developed asthma last year and it was stressful to watch him struggle to breathe. He is now stabilized on an inhaler 2 x per day. I do use 2 Coway airmega AP-1512HH mightys in my 450 square foot bedroom. Your living room is under 300 square feet, but what is the ceiling height? That will also factor in. The Coways are pretty loud on the highest setting, but I usually run them on medium and they aren't too loud for me on that setting. I did have my indoor air quality tested, and the inspector that collected the samples said that my purifiers were doing a good job, as my indoor air was similar to the outdoor air in quality.

I’m a Coway believer. We have a big one for downstairs and a small one for my son’s room as he’s allergic to the world. I’ll probably buy another big one soon. Best part is? They tell you when they’re working. Helps a TON in the kitchen. Even when my dog runs by and pet hair flies around it turns on. It’s amazing.

This is the big one we have. Best bang for the buck IMHO: https://cowaymega.com/products/mighty-ap-1512hh And this is what I have for my very allergic son’s room. https://cowaymega.com/products/airmega-100

I just bought this in less than 2 minutes after reading this post. If you're a bot, you're a good bot.

I have this filter with pets in the home and I do recommend it. But speaking from experience, if you are not regularly dusting and vacuuming and washing things like pillow covers, it won’t really help your friends. As far as clearing fur from the air: not really. The pre-filter does pull in dust and fur, but there will still be plenty on the ground and every other surface. It does get loud on basically all but the lowest setting. Anything higher than that and I turn up the volume on the TV, can’t hear conversations in other rooms, etc.

Big advocate for the coway air mega 1512HH or something like that. It’s wirecutter’s top pick. Indeed quiet, powerful, easy to clean. You can turn the lights and ionizer off easily. Replacement filters are like $12-15 each and I can usually go 12 months before needing to change. People have good things to say about Winix, but they’re quite bulky/large in my experience.

Over and over, the Coway Airmega AP-1512hh is one of the most consistently high rated (If not highest rated) air purifier on the market and has been for years. Go on YouTube and almost every video recommends it. I have one and it’s great.

Coway Airmega AP-1512HH Mighty. It's been wirecutter's top pick for years.

I have a different Coway (the 1512 that Wirecutter has recommended for years), and I do wish it were easier to tweak remotely, but the power on memory means I can at least toggle it on/off with a smart outlet.

I'm 15 years into a Coway 1512 (now AirMega) and it's still ticking. Air quality sensor goes red when I preheat the cast iron, blasts for a few hours, stops. I gift one to family if they start house remodels.

Coway Airmega AP-1512HH Mighty for 151 on amazon is my top choice. The 4-stage filtration system (pre-filter, HEPA, carbon, and ionizer) is super effective at removing dust, allergens, and odors. Other alternative if you have more budget would be Coway- Airmega 400. it's around 500 bucks but it's recommended for users with extremely sensitive reaction from dust, dust bunnies, and smells. FWIW, my mate and I recently did an analysis on Reddit data for air purifiers. Basically ranked them by aggregated sentiment.

Many good reviews about Coway - Airmega AP-1512HH Mighty. It has HEPA filters together with the pre-filters, carbon, and ionizer. Many users would report having to reach out to their inhalers to months instead of weeks. But you know that you have to remember to not skip to replace it from time to time as it looses it's effectiveness. It's 229 bucks on amazon if you're wondering. Winix 5500-2 also would be on my top choices for 346 bucks on amazon. FWIW, my mate and I recently did an analysis on Reddit data for air purifiers. Basically ranked them by aggregated sentiment.

Winix 5500-2 or AM80, or Coway 1512 offer the best bang for the buck in terms of finished units as they sell for about $150 on sales--they mainly remove particulates, but for allergies, this is what you want. Each cover about 350-400 square feet of space for optimal performance and air quality, and they represent the most cost-effective performance relative to unit size/price/energy use/filter replacement costs. Buy as many as you need for your living space's size. Corsi-Rosenthal boxes are even less expensive.

Winix 5500-2 or AM80 (same unit, different look) or Coway 1512. They optimally cover 350-400 square feet a piece. They are the best bang for your buck when considering airflow, energy usage, and filter replacement costs. You can find them on sale for around $150. There are good aftermarket filters for them, too, from brands like Filter Monster, that further bring down operating costs (I've been using several Filter Monster products for years now and previously tested their particulate performance using a Purple Air PA-II--they perform comparably to factory filters.) Smaller units are actually less energy efficient due to a need to run on higher fan settings and larger units often have much higher purchase and filter replacement costs (although some are extremely energy efficient). Most air purifiers **do not** remove odors. They can disperse them by moving air around, but they do not have enough carbon to provide a significant level of adsorption to remove VOCs for any sustained period of time. Specialty purifiers that have large carbon canisters exist, and these work very well at odor removal, but they have some major downsides, such as price, energy usage, carbon canister replacement costs, and noise. Beyond that, air purifiers that excel in VOC removal sacrifice particulate performance, as you want slower airflow for adsorption (to allow sufficient 'dwell time' where the air is passing through the carbon bed), versus higher airflow for filtering particulates. An example of a purifier that removes VOCs is the AllerAir AirMedic Pro 6. I have one with a 40 pound Vo-Carb carbon filter and it was about $1,000 to buy, it's massive, loud, uses a ton of energy as it has a commercial motor, and the carbon canister is several hundred dollars to replace. Unless it is not possible, ventilation with outdoor air is a much more effective way to remove VOCs (and hence, odors.)

That is the one downside. The AM80 looks a bit better--I have several of them and they are not as obtrusive. The Coway 1512 is available in white and it looks pretty good in person.

Winix 5500-2 and AM80 (same unit, different look) and Coway 1512 are the best prebuilt units from a value perspective and can be found for around $150 on sale. Smaller units and larger units are less efficient, and buying several 5500-2s is more effective and efficient than a single large unit when factoring in things like purchase price, energy use, filter replacement cost, and effectiveness at filtering particulates. Each 5500-2/AM-80/1512 covers about 350 square feet optimally, although you may need more filtration than that for severe smoke. There are good quality aftermarket filters for them that are significantly less than the factory filters and perform equally well. If you are on a major budget, build a Corsi-Rosenthal Box. They are as effective as they are ugly--if you need air filtration in a pinch or on a budget, they are exceptional. If you want a real BIFL purifier that will last like 30 years, the AllerAir AirMedic line is built to this standard, but they also have some significant drawbacks and are not a great match for someone just looking for particulate filtration.

None of them use monumental amounts of energy except the ones that actually are BIFL, as these use commercial motors. Those use a lot of energy. For most, the Winix 5500-2 or AM80 (same product, different look) or Coway 1512 represent the best value of cost, features, efficiency, effectiveness, filter lifespan, replacement filter costs, generic replacement filter longevity (see Filter Monster), and longevity. They often go on sale for around $150. These units provide optimal performance for up to about 400 square feet. If your living space is larger, you would need multiple units placed in different areas of the home to get the best results. Multiple smaller units generally provide better performance than a single, larger unit. Both of these have reusable prefilters, which if cleaned often, will extend the life of the pleated HEPA filter (which cannot be cleaned). They also both have sensors that allows them to ramp or reduce fan speed based on air quality readings. The Winix has a really nice night mode, where it ramps down the fan speed when air quality is good + it is night, and it also dims all of the LEDs. Keep in mind though that the higher the fan speed, the more air turnover you get, and the faster particulates (including allegens) that are in the air will be filtered. If your roomate's allergies are severe, keeping them on a higher speed continually might be necessary to achieve allergy relief. Finally, keep in mind that most purifiers do not do much for odors or volatile organic compounds. (It doesn't sound like you are buying it for this reason, but I still wanted to note this.) There are specialty units that do offer significant VOC adsorption capacities, but these are specialty products that are generally extremely expensive and have quite a few downsides.

They absolutely work at filtering particulate matter (PM) from the air, and PM is liked to millions of premature deaths every year, it is especially harmful to children, plus it is causally linked to the onset of certain diseases. The do not work very well at filter volatile organic compounds (VOCs), unless they are specialized units with massive carbon canisters. Consequently, they are not effective at removing odors unless they are one of these specialized units. In your stated case, you're describing particulates, so you do not need a specialized unit. You simply need enough filtration to cover your home. What size is your home? Generally, multiple smaller units are more effective than a single, large unit. The Winix 5500-2 or Winix AM80 (they are the same product with a different look) and the Coway AP-1512 represent the best values between airflow, features, energy efficiency, and filter replacement costs. These provide optimal filtration for up to about 400 square feet per unit. Multiple units throughout the home in different areas will achieve the best results. The larger Coway AirMega 400 is on a great sale right now. This is a good unit. While Coway advertises it for covering over 3,000 square feet, this is not accurate (and is 'optimistic' marketing), and it will provide *optimal* filtration for around 600-700 square feet.

The Winix 5500-2 or AM80 (same unit different look) and Coway 1512 are the most cost-effective units short of building your own Corsi-Rosenthal Boxes. Multiples of these units are cheaper to run than one very large unit. Yes, they make a huge difference in removing particulates from air. Particulate matter is linked to the deaths of millions of people every year and it wreaks havoc on the human body--especially that of children. The lower the PM levels indoor, the better, and purifiers/CR Boxes are extremely effective in lowering PM. They do not remove odors. Only specialized units with large carbon filters designed for VOC adsorption can do this, and these units are extremely expensive to purchase and operate. If you are on a budget, you can build your own purifier, called a Corsi Rosenthal Box. They are cheap, ugly, and extremely effective at removing particulates from the air.

Coway AP1512. Simple to clean, easy to get replacement filters and relatively inexpensive. Gave an old one I have is five years old and still working perfectly. 

Hi everyone, I'm in the UK, and I'm looking to decide on a new air purifier. Currently, I have the Coway Airmega Mighty AP-1512HH, and I really like it. Tempted to get that again but also very interested in the Philips Series 3000i, WINIX Zero-S, and the Coway Airmega Jet. I'm also open to the idea of an air purifier with a fan function, but from what I've read, they might be trash... I live in a very dusty part of London with poor air quality, and I have two dogs and two cats. I'm VERY anxious about making the right choice, and I've made a comparison table based on various models I've been browsing. Wasted waaaay too much time on this. Please give me your help Reddit!!!

Hi! Thanks for the responses everyone! And the kind words about my data. Obviously feel free to use and no need to credit, but I'm not averse to being credited either. I'm not sure about the size of my current double bedroom, but I'm moving into a new build surrounded by building sites in November which will likely have a bad air quality for the next few years! That's 555sq ft. Update: today I picked up a second coway airmega for the bargain price of £50 secondhand on Gumtree. Owned by a woman whose son bought it when he came to stay last summer and other than that hasn't been used. Nice! I've been spying an IQAir Health Pro plus on eBay for around £350. More than I want to spend but seriously considering due to moving in to this new build later this year with all the building site dust we'll be expecting from surrounding sites...

I've had really good experiences with the Coway Airmega Mighty - I've bought 3 so far, as I'm always scouring eBay for good deals. I've also bought an IQAir250 as I found a great deal on it but haven't picked it up yet :)

> Coway Airmega AP-1512HH Mighty. I've had one since 2021 and I love my giant Ipod shuffle!

We’ve had AirMega for years and love it. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

Austin Air is overpriced, and sounds like a jet aircraft taking off. For contrast, look at the Coway Airmega 400, or the Airmega400S (for "Smart") if you want detailed sensor readings/remote operation. For that size room, you could even start with the Coway AP-1512HH and then add a second unit if the one wasn't enough.

Idk, I don’t find the Airmega 1512hh helpful when it comes to smells. The carbon sheet feels useless in comparison to pelleted carbon. I’m a weed smoker and my Winix has made a night and day difference compared to the Airmega. I was shocked to discover it's pretty common for air purifier companies to mislead when it comes to room coverage. For folks with allergies, using an air purifier for virus (COVID, flu, RSV) mitigation, smoke, dust, etc. a purifier really makes the most difference when air in the room can cycle through the filters a number of times per hour. With that it in mind, the recommended room size changes. The Airmega is rated for about 300-350 square feet but that's only based on testing it at its highest fan speed. It's presented very differently in Wirecutter and Amazon when it comes to recommended room size. I've come to find resources for better assessing air purifiers. https://housefresh.com/coway-airmega-ap-1512hh-review/ https://www.airpurifierfirst.com/review/coway-ap-1512hh/

There’s a House Fresh article about the best air purifiers for viruses and bacteria. Sadly the Coway wasn’t on it. I wish I had came across the article before I bought my Coway 1512hh. The Winix 5500-2 is listed as a good buy for viruses. I ended up buying it for my living room and have the Conway in my bedroom. At some point I’ll upgrade to the Winix. Update: A few months ago I was looking at Coway's website and thought I didn't see viruses listed in terms of what their HEPA filters can filter out for the Coway 1512hh. I just looked and it's listed. Definitely put me at ease and I can cross getting another Winix for the bedroom off my list.

Just looked up the verified square footage for the 1512hh and it's 360. (Going by the Association of Home Appliance Manufacturers stats) It would be slightly underperforming in your space. I've read when airborne viruses are a factor in your air purifier purchase you want to aim for 5-8 air changes in an hour. I rarely have people over so I'm fine with 5. Once I start having guests over I'll aim for slightly higher air changes along with opening my windows.

Just comparing the Coway 1512hh to the Winix 5500-2 I'd say Winix is slightly better due to the carbon filter and having an additional fan speed. You are correct, the square footage is based on the device running at the highest speed. Both devices are verified for 360 square feet. OP, you might want to look into the Association of Home Appliance Manufacturers' directory. It allows you to see what square footage an air purifier is verified for. I may have mentioned Coway isn't in it. Another option would be to look at the different devices on Coway's site and look at the square footage for a device in 12.5 minutes, that way it's giving you the square footage for roughly 5 air changes an hour.

They’ve massively oversold how large of a space this device is suited for. I found it did nothing for odors. Great for small rooms in which odor isn’t a concern.

Correct. I wish I had realized that before I bought it but oh well. The carbon sheet is advertised to make one think it will help with odors. Live and learn

I have two dogs and a cat, and honestly, getting an air purifier was one of the best decisions I’ve made for my home. Pet hair and dander were everywhere, no matter how much I vacuumed or groomed them. Plus, there was always a lingering “pet smell” that I couldn’t get rid of. After doing some research, I ended up buying the Coway Airmega AP-1512HH Mighty, and it’s been amazing. It handles pet hair, dander, and odors like a champ. The HEPA filter traps tiny particles, and the activated carbon filter really helps with smells. My house feels fresher, and even guests have commented on how clean the air seems.

I recently got the Coway Airmega AP-1512HH Mighty, and it’s been a game-changer for my home. I was skeptical at first, but it really does make a huge difference in air quality. It’s super efficient, quiet, and the display can be turned off, which is great for bedrooms. Plus, it’s really affordable compared to some other models out there. I’ve seen it reduce heavy smoke pollution by almost 99.6% in just 30 minutes, which is impressive.

For the first 15 years of our lives as parents we lived in an old Victorian house where the bedrooms were downstairs in the unfinished basement. Dust was always a problem for both my wife and our eldest kid, and probably there was to some extent mold down there too. We put a Coway Airmega AP-1512HH in the main downstairs hallway and it made everyone's allergies 100x better within days. It didn't even have to run continuously: we set it on "eco" so it would gently sample the air every 30 seconds and go to work only when it detected particles in the air. I love how simple and reliable it is. The little lights indicating when it's time to change a filter, and which one, are no more complicated than they need to be. The HEPA filters aren't cheap, but on "eco" we don't go through more than 1 every year (YMMV). I set a reminder to dust the outer filter and sensor every month (30 second job), and that's kept it running like new. Since we moved I bought a second one to stick in an out of sight spot on the main floor, where I can't see much more than the top panel where I'll know when it's time for a new filter, while our trusty old white one sits in the hallway upstairs. That second one I bought used, and got it for a great price because it was so scuffed up. Just a wonderful appliance that does exactly what it's supposed to. Unexpected benefit: I've recently switched our furnace filter replacement cycle from 3 months to 4 months because the last few came out looking brand new. I'll probably end up at a 6 month cadence before I feel like the filter's actually in need of replacement, and we're pretty sure it's due to the Coway filters pulling things out of the air before they get sucked through the HVAC return. That's not *quite* the Coway filters "paying for themselves" but it's a factor.

I have 3-4 Coway Airmegas and Winix 5500s. I found them all on my local Facebook Marketplace for $50-75 over the last 12 months. All in great condition. Previous owners sold because they were moving (college students; young professionals).

I have both the Winix 5500 and Coway 1512. Both are great. I find them on Facebook marketplace for $50-75

Buyers guide is outdated with misleading information about ionizers. AP-1512HH started production in 2016. Filtration system is outdated and it’s noisier than newer models, that are much better.

Slightly underperforming - no. 360sqft is on highest mode 24/7. The noise can become unbearable and people will switch to lower modes, thus being ineffective. We reccommend our customers to look for 30% bigger devices. Going to Winix from Coway is a downgrade.

The jet kicks winix’s ass. Filtersystem is better on the Jet - Hepa filters design is up to date and fits snug inside, pre-filter before the carbon filter to prolong hepa filters life. Also, you can use the Jet as a fan and blow air out from the front circle. Last but not least, Winix does not update its filters, but Coway applies it’s latest filter technology on all of their filters. Even on Coway Mighty, that is 8 years old, but the design is still bad.

I’ve used [Conway Airmega AP-1512HH](https://www.amazon.com/gp/aw/d/B01728NLRG?psc=1&ref=ppx_pop_mob_b_asin_title) for years and they work great. They consistently get top rankings from NYT Wirecutter.

Coway AP-1512HH Mighty Air Purifier Works great. I only turn the ozone on when someone in the house is sick, but I swear it makes a huge difference.

I own 2 and second this recommendation. They do what I bought them to do. Cleaning the filters makes it VERY clear how much garbage they pick up. They’re quiet and they work.

Actually, blueair makes some of the best air purifiers available. There's a really short list of reliable manufacturers: blueair, levoit, coway, and winix. The benefit of buying something like a winix 5500 or a coway 1512, is that the filters are rectangular, and there are a kajillion of them so there will always be a market for replacement filters. VOCs is a whole separate thing.

I hope mold remediation works out -- removing the sources is always the best place to start. The furnace filters used in CR boxes are not as good at capturing as hepa filters in many at-home air purifiers. The CR project is a low-cost way to get lots of clean air quickly, but aside from cost aren't competitive with air purifiers. One air purifier hepa filter can cost as little as $20 each year. (Specifically, the coway 1512 using replacements from durabasics or cabiclean.) If you can afford enough purifiers from coway, levoit, blueair, or winnix, then go for it. These are the purifiers most people trust and recommend. Some don't like ionizers because they think that they create problems by putting out their own VOCs. Most air purifiers have an on/off feature, but at least some Winnix purifiers don't have one and turn on the ionizer on automatically (I'm not sure, I haven't used one). I saw a Q/A recently where someone was trying to clip the ionizer out of their coway purifier, even though it has an on/off function for the ionizer. I guess they didn't trust it. So yeah, some people really, really don't like ionizers. I personally prefer coways, and at one point when I had an apartment, office, and a studio I needed to keep clean, owned eight of them. While many were used and gotten from CL/Ebay affordably, I got proficient enough at opening new ones that I timed a 2-minute speed unboxing and setup video. Would recommend.

I mean.... I mentioned the part about them having no reviews and being at a sketchily low price point of 1/2 to 2/3 the cost of everyone else. There are really only a handful of air purifier brands that have demonstrated reliability, affordability, and effectiveness over several years, and don't dabble in post-apocalyptic/steampunk decor -- coway, levoit, blue air, winix. If you want to pay more, there's iq air, alen air, and a few others. For $110, you could have bought a blue air 511 and almost a 411, a levoit 300, almost a Levoit Vital 100s, or a Winix a231. The winix 5500, the coway 1512, levoit vital 200, and the blueair 311 are all at this CADR, but for closer to $200.

Are you looking to move one purifier between your bedroom and living room? I would *not* recommend Airpura or AllerAir unless you have a serious gas/vapor/odor/VOCs issue that can't be mitigated with source control or ventilation. In that case, you'd choose one of their heavyweight carbon purifiers. Airpura and AllerAir do make more particulates-focused units, but they don't list particulate Clean Air Delivery Rates (CADRs). They're also known for be very loud. Both are Canadian companies that manufacture largely in Canada and some components in the USA. Levoit is lower quality than IQAir and Coway. The [IQAir Atem X](https://www.iqair.com/us/products/air-purifiers/atem-x) you linked in a comment is high quality and has CADRs in the 400s CFM, but it's very expensive per CADR. As for "True" HEPA, I would say that listing the standard and filtration efficiency at Most Penetrating Particle Size (MPPS) gives you the best idea of performance. There are several HEPA standards. But I don't think there's a significant difference between brands on this front; they will still clean your air. The [Coway Airmega AP-1512HH Mighty](https://cowaymega.com/products/mighty-ap-1512hh) you linked is commonly recommended. It's a good price point and attainable for many. But the Mighty has a few drawbacks like being less energy efficient, somewhat loud, and occasionally people have reported balance issues (e.g., purifier "walking" across a floor). The [Coway Airmega 400](https://cowaymega.com/products/airmega-400) was probably recommended in part because it's "oversized" for your bedroom. Oversizing allows you to run the unit on a quieter setting while hopefully maintaining CADRs. ➡️ If you're expecting one purifier to clean both the living room and bedroom areas, I would also recommend the Coway Airmega 400. The highly upgraded pick would be the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox). Top Smoke CADR is 568 CFM. It has wheels so you can move it around easily and it shows PM10, PM2.5, and PM1.0 concentrations. Obviously the ProX is fairly big. Keep in mind that CADRs apply to the highest airflow speed/setting *only*. Lower settings have lower CADRs, which reduces cleaning effectiveness. Right now there aren't any fantastic sales directly from Coway. But you can use the discount codes **COWAYMEGA10** or **FORYOU10** for 10% off most items.

Minimum CADRs for a 400 sq. ft. space (with an 8 ft. high ceiling) would be 267 CFM. With allergies, we generally recommend higher than minimum CADRs to reduce symptom severity. The [Coway Airmega AP-1512HH Mighty](https://cowaymega.com/products/mighty-ap-1512hh) has a top Pollen CADR of 232 CFM; it also has an ionizer. If you keep the ionizer off, it's possible the Pollen CADR would be lower. The [Coway Airmega 240](https://cowaymega.com/products/airmega-240) has a top Pollen CADR of 343 CFM and no ionizer. If you want to buy directly from Coway, use the codes **COWAYMEGA10** or **FORYOU10** for an extra 10% in your cart. That should lower the price of the Airmega 240 to $246.60 (before any applicable taxes).

The Coway AP-1512HH is the real deal; used it for many years and having running 24/7. I have an air quality sensor device that verifies that it does in fact purify the air as well as it claims.

If you take an air quality moniter, like the GQ Electronics air 760, and get the reading for the PM 2.5, you will see that it is not a waste of money....with the coway ap-1512 the reading is 000, totally clean.

You can do the ol' trick of taping a furnace filter onto a box fan. If you want an actual product, look at the Coway AP-1512HH. About $200 but goes on sale frequently. Knockoff filter replacement sets are about $25 — you only need to replace the hepa filter once or twice per year so it's not a huge ongoing expense. Definitely clean the pre filter monthly and wipe down the door that covers the filters at the same time.

I recently bought the same Coway you show, and I love that it's quiet and the big light for particlate level can be shut off. I bought it when I decided to stop taking allergy meds after about 20 years. I bought it straight from them, not sure if that's an option in Canada. It shipped and arrived quickly. [Coway Airmega](https://share.google/urqdOD8iBxey5yWNF)

I recently bought the Coway Airmega AP 1512HH, recommended by NYT Wirecutter. They also recommend a different model Coway that performs the same but just looks different. I'm super satisfied with it. It's amazingly quiet at low and medium settings. I wasn't dealing with any smells, just dust mites that cause allergy symptoms while I try to sleep. It seems to be doing a great job.

Also, I bought it direct from Coway and it arrived quickly. Highly recommended.

I've had the Coway Airmega AP-1512HH for several years now and it's great! Even on the medium setting it's not very loud and my allergies are noticeably better since getting it. It's highly rated by [Wirecutter](https://www.nytimes.com/wirecutter/reviews/coway-ap-1512hh-mighty-air-purifier-review/) and [rtings](https://www.rtings.com/air-purifier/reviews/coway/airmega-ap-1512hh-mighty) if you want to read some more in-depth reviews.

[Coway Airmega](https://a.co/d/iZfdWnP) is my first choice, I also have this [Levoit](https://a.co/d/6AN2VMi) one and I really like that it has WiFi to report on the filter health in real time.

I have 3. A Coway Airmega, a Levoit Vital 200S-P, and a Welov. None of them do ionization (bad for their lungs and our lungs). The last 2 are smart/wifi ones that let me see the filter life in the app, that feature I appreciate since with birds the filter runs out waaaaaay sooner than the “change every 12 months” recommendation.

Oh wow, I have both these, too. Both are fantastic. Coway is better at air purifying but is loud and lacks smart functions. The levoit one is pretty damn good too, and quieter with tons is smart functions.

My Coway definitely stops the smell from the box.

Coway Airmega AP-1512HH(W) True HEPA Purifier with Air Quality Monitoring, Auto, Timer, Filter Indicator, and Eco Mode, 16.8 x 18.3 x 9.7, White

[Coway ap1512hh](https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-White/dp/B01728NLRG/) is the way to go. Been on wirecutters top list for years now.

We use the Coway brand similar [to this](https://cowaymega.com/products/mighty-ap-1512hh?variant=33436620783751&country=US¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gclsrc=aw.ds&&utm_source=google&utm_medium=cpc&utm_campaign=20932153416&utm_term=&gad_source=1&gad_campaignid=20942052913&gbraid=0AAAAADfuQBo62o1CUr7bLXXm8tvFHcIwb&gclid=CjwKCAjw87XBBhBIEiwAxP3_A1Sdfs3M3uiL9mdY3Nq8fp3c31p_Va2iGp30RwELs7EpGsjTj6WrHxoCdC8QAvD_BwE) and they work great. We use them for wildfire smoke as we live in an area that can get inundated.

Coway is the answer. They have lots of different models but I would recommend the Coway Airmega AP-1512HH. They have bigger units to cover larger areas but I've found that instead of spending $550 on the bigger unit to cover 1500 sq ft and placing it in a central location it works better to get several of the smaller units I recommended for the same price and place them in specific rooms. Its much more effective. For example put one in your bedroom, living room, kids bedroom, and living room, kitchen etc. The Model I recommend comes with an ionizer capability. I'd recommend turning that off (just press the button). Some research has come out that ionizers are good to be around.

I just bought an air mighty second hand and it is so dusty any recommndations for cleaning. So far I have thrown away the old filters, washed the prefilter and cleaned all the bits I can access with alcohol wipes. I can’t get into the main body behind where the filters go. Just wondered if you have any tips or should I leave it there. For some reason I feel a bit icky about it and want to take it apart completely. Please talk me out of it !

I had a smell for a few hours after turning mine on. Just ran it with the window open in my bedroom for a few hours and the smell was gone.

Don’t overthink it. So your room is 15 m2, so 161 sq feet in North American right? I personally use Coway so I can only reccomend them from my experience. I have a Coway Airmega AP1512 for my 150 sq foot bedroom and a Coway Airmega 400 for my 600 sq foot main living space (kitchen, den, dining room) I’d highly reccomend the AP1512 for your small space. https://www.nytimes.com/wirecutter/reviews/coway-ap-1512hh-mighty-air-purifier-review/ With that being said, I’m sure the Winix is a great unit too!

I have been very happy with my Coway: [https://www.amazon.com/dp/B00BTKAPUU/ref=twister\_B0DC69QWGC?\_encoding=UTF8&psc=1](https://www.amazon.com/dp/B00BTKAPUU/ref=twister_B0DC69QWGC?_encoding=UTF8&psc=1) I bought it for the California fires - but continued to use it because of pets.

1512 and 400. I love the both

Nice find-using that data helped me pick the Coway AP-1512HH that keeps my 400 sq ft room allergy-free without sounding like a jet. True HEPA plus real carbon pellets, auto mode stays under 25 dB, filters are about $45 a year if you swap prefilter monthly and HEPA yearly. I logged sensor drops with a Qingping monitor: PM2.5 fell from 35 to under 5 in 20 min. If OP needs something smaller, the Levoit Core 300S is almost silent but struggles above 350 sq ft, so run it on high for an hour before bed. Airtable and IFTTT handle the sensor logs, and Pulse for Reddit quietly pulls fresh user reviews so I can tweak settings fast. Data-backed picks like that Coway beat endless scrolling.

You don't need an expensive one, you just need one that seals well around the edges with a HEPA filter. You could even make one with a box fan, a filter and some tape. More expensive ones might have higher throughput or some other small advantages, but we've always just bought more rather than more expensive which allows for better targeting of specific areas like the bedrooms. The best value one I've found here is by [Winix at Costco](https://www.costco.com/air-purifiers.html?brand=winix&refine=%7C%7CBrand_attr-Winix). NOT the one they sell online. There's a white one that they frequently sell in the store. I've gotten it for as little as $130 on sale. It comes with 2 replacement filters as well I believe. I don't like it in the bedroom because the bearings on the fan aren't as good as some others so it will occasionally make a little clicking noise as the fan spins, but its perfect for other areas of the house. For the bedrooms we got this model by [Coway off of Amazon](https://www.amazon.com/dp/B01728NLRG). Nice and quiet, works well. Don't put humidifiers anywhere near the filters. It tends to trigger the sensors.

Coway Airmega, either the AP-1512HH or 200M (same guts, different faceplate).-

I’ve had my Coway 1512 on continuously for 10 months straight so far and no issues

There is basically no carbon filter in this so it won’t filter odors at all…

We have had our first Coway 1512 for about 3 years and just bought two more this past year. We've been super happy with them. There are off-brand replacement filters online and they don't need to be replaced super often.

This is true. I use it as a white noise machine for my toddler and he loves it. It’s very loud on level 3. Much quieter on 1 and 2.

The Shark air purifiers don't review well, but I have a Coway Airmega AP-1512HH(W) and I'm not sure it's really cleaning anything. I hear it kick on but nothing feels any diffrent.

I have two Coway Airmega AP-1512HH, one on each level and as someone with terrible allergies, it's made a huge, noticeable difference. Last year my allergies started to get really bad again, and I couldn't figure out why. Turns out my 6 month autodelivery of replacement hepa filters got skipped and I didn't notice. It was 2 months past due for a change, I changed them and almost instantly my allergies went back to my normal manageable symptoms. They have a smart mode where it will turn up when it senses bad air quality which has been awesome, but also mildly terrifying. Awesome because it has turned up when a toddler as walked by alerting us to a poopy diaper. Terrifying because my husband burned some food really badly and it kicked into high and cleaned the air so much and so fast it didn't set off our smoke detector. We installed more smoke detectors after that.

I have 4 of these in my house. The filters are reasonably priced on amazon too. I replace the filters every 3 to 4 months.

Id go with the [Coway Airmega](https://productbible.com/product/coway-airmega-ap-1512hh). its quiet and has made a big difference for my allergies. My place feels noticeably fresher and I don’t wake up as stuffy anymore. Filters are easy to swap out too.

Yeah sorry if that seemed overly snarky but basically - although most people have stuff in their air, it’s not clear that everyone needs an air purifier. The first question I always ask is what problem you’re trying to solve - if the answer is (as it sounds like) “well I must have stuff in my air”, then I advise you to get a very basic unit and run it in your bedroom with the door closed to see if you notice a meaningful difference. At the $100 price point you could get a Levoit Core 300, of course we tend to recommend jumping up to $150 and getting a Coway Mighty or Winix. But without knowing your actual air composition or any health issues or concerns, all we can do is recommend a general purpose unit. And honestly it may or may not even be necessary.

So here's the thing - no matter what anyone tells you, there is no magic box that will do what you want. Air purifiers move air at relatively low speeds through a fairly restrictive filter. That means that they only "clean" an area of about 300sqft. around the unit effectively. They are almost universally ineffective through doorways, around corners, etc. If you have HVAC, the single best thing you can do is put a better filter in and run it on "always on" (not "circulate" or "auto", but ON). The best filter for a 1" insert (the most common) is a 3M Filtrete 1900. They're $20. The problem is they clog quickly, so you'll likely have to replace them every 30-60 days. That said, it'll cover your whole house. If you don't have HVAC, you could consider an AirFanta or building your own CR box. They're ugly and loud, but they move a lot of air. Again, I'd use those 3M filters if you want to stop smoke. Dust and other allergens, any ol' filter will do. The "traditional" route would also be to put several purifiers in your home, sized appropriately for the rooms - a large one for the open living space, and smaller ones for the bedrooms. I have the following setup: 1st floor, 1000 sqft, semi-open plan: I have an IQ Air and an Austin running at opposite corners of the home on a constant speed of medium. 2nd floor (bedrooms, also 1000 sqft): Master bedroom has a Coway 250, guest bedroom has a Winix 5500-2, both kids' bedrooms have Blueair 411's. Finished Basement (also 1000 sqft): Coway Mighty and Winix 5500-2 at opposite ends, running as needed (since the basement gets less outside air) and the one bedroom down there has an aging but still functional HEPA from Idyllis/3M (the Lowes brand) that was purchased years ago but uses 3M HEPA filters. IN ADDITION, I use MERV13 in my furnace and my ERV. The air here is VERY CLEAN. (Bad allergies run in the family...)

You have a cat - be aware, hair will get in the unit. DO NOT buy a cheap round purifier. They will get fouled very quickly. Levoit VITAL (not Core) is a good choice. As is Winix 5500-2, Coway Mighty or 150. 3 rooms at 300 square feet each shouldn't be an issue, but you may want to size up for the largest space (living room, I'd assume) which could certainly use a Coway 250 instead. If it were me, I'd do Coway 150 or Winix 5500 or Levoit Vital in the bedrooms, and Coway 250 in the living space, unless your master bedroom is bigger. In our house we have Coway 250 in the Master, smaller units in the other bedrooms, and another larger unit in the living area.

So you're focusing on the wrong things. Almost all units we recommend are H13 rated. Coway, Winix, even Levoit Vital. And third-party testing is ... not super relevant at this price point. You want a Coway 250 or Levoit Vital 200 for the upstairs and a Coway 1512 or Coway 150 or Winix 5510 or Levoit Vital 100 for the downstairs.

Seconding that unit. We're in CA and during the height of wildfires a few years ago (I think?), we scored one for a good price. That sucker kept us sleeping well.

I have this [Coway](https://amzn.to/4iSMzhj) and we run to 24/7 in our bedroom. It does a great job, and also functions as a white noise machine on the higher fan settings. I love that it shows you if it detects particles in the air. It’s currently on sale too!

I've got 2 of those Coway HEPA purifiers that look like a giant ipod shuffle, one on each floor (this: [https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-White/dp/B01728NLRG?keywords=coway%2Bair%2Bpurifiers&qid=1678993743&sprefix=coway%2Bair%2Caps%2C78&sr=8-3&th=1](https://www.amazon.com/Coway-AP-1512HH-Mighty-Purifier-White/dp/B01728NLRG?keywords=coway%2Bair%2Bpurifiers&qid=1678993743&sprefix=coway%2Bair%2Caps%2C78&sr=8-3&th=1) ). I generally have bad allergies and a pet and they do a very nice job imo. Our kitchen doesn't have an external exhaust fan and the coway that is downstairs does a good job sucking up the smoke and odors from that as well, we have it set on to kick on automatically. Also does a nice job in the bedroom at keeping the place not smelling like dog.

yes! got mine during pandemic

what i got is ap-1512hh. i got it thru facebook but they also have it in shopee

NYTimes recommends this one after testing over 60 purifiers - [https://www.amazon.com/dp/B01728NLRG/?tag=thewire06-20&linkCode=xm2&ascsubtag=F0401HZT0QH7PFDPAWSWT7DTCW6SQ](https://www.amazon.com/dp/B01728NLRG/?tag=thewire06-20&linkCode=xm2&ascsubtag=F0401HZT0QH7PFDPAWSWT7DTCW6SQ) I have it and like it. As always, a lot comes down to getting the right size, placing it in the right place, using the right filters, and cleaning regularly.

Coway Airmega AP-1512HH is the best imo, definitely makes a noticeable difference in the freshness of the air in my home. filter changes take just a couple minutes, i also like that you can turn off the glowing front light for dark rooms

I use the Coway because it's really affordable and performs well (on Wirecutter's list of best air purifier). I don't have allergies, but it cleans the air of odors really quickly.

I have both the Coway Mighty and Austin Air Health Mate Plus.  The HMP was pricy but I haven't needed to replace the filter yet, despite a couple of years with pretty bad wildfire smoke. We run all of our air purifiers 24/7.

I am using Coway AP Mighty for over a year. I think you should look into it, also you can look here: https://www.reddit.com/r/homeowners/comments/1iu87rd/air_purifier_for_your_home/

We really like our Levoit brand ones. Locally our energy company has discounts on them if you buy through their program so I would do that if I was buying another, may be worth checking.  The coway air mega mighty are also popular. We stayed with friends out west during one of the big fire years and it was amazing at both the smoke and the dog hair from their dog. 

We have had one in basically every room for years, and it's made my husband's asthma/allergies non existent at home. He used to have them really badly. We also have two dogs and there's never any fur or smell around the house. It also really cuts down on the amount of dust in the house. I always follow wire cutters recommendations. We have blue air blue pure 511 in most rooms and love it. We've had the coway mighty for close to a decade now. We originally bought it back when we lived in a studio, and it now resides in our main bedroom. This has an automatic setting where it increases speed when it detects air pollutants. It's been really interesting over the years to see what sets it off. Aerosols for makeup, shaking out sheets, cooking without windows open, humidifiers without filters. We've changed what we use in the house based on it because I'm concerned about lung health in general, because of my husband's poor lung health. It also is great for smells around the house, and in general for when you accidentally burn something on the stove, etc. it clears it out a lot faster. We do still open windows to air things out and have an HVAC filter, but this just is makes an additional difference on top of it. But also keep in mind we live in the city and have only one level. That probably makes a difference in whether filters are useful or not. Also my husband and I never transfer illnesses to one another anymore since air filters. Not sure if it's related or not As far as features I recommend getting one that has a night mode and keeping it on so there isn't any extra light pollution in the bedroom.

Been thinking about ti for my own classroom. I have 2 Coway mighty-s at home that I love but not sure i can fork over that much $ for my classroom. What did you end up doing?

I have 4 coway mighty Love it Seriously cuts down on cat fur (I have 2 fuzzy babies)

Oversized hepas are better. It allows you to run them at lower speed and still get good air flow without all the noise. We run coway air mighties on level 2 in four bed rooms and levoit 600s on level 2 in the two large open spaces. If I were buying now I would probably get levoit 400s for the bedrooms because the smart rules and scheduling is helpful and they are often very cheap on Amazon warehouse. Noise is barely noticeable and the amount of dust they pull out of the air is shocking. Bonus that we never have to dust surfaces. They are also great to have during annual west coast wild fire smoke season and keep particulates in the house undetectable even when it has been horrid outside. Other good additions if your furnace can handle it is a merv 13 filter on the central HVAC. We also donated them to the kid’s schools that didn’t have them to help manage particulates, air bourne microplastics, and wildfire smoke there as well.

Coway Mega mighty is excellent. Change the filters annually. It detects everything and cleans the air so fast and low energy. I love mine. I have it on eco mode mostly.

The biggest mistake you can make when choosing a purifier is getting one that is undersized for your space. You really need to figure out the volume of the room and then see how much CADR you require for the space for the number of air changes you want. Also, take into consideration that CADR numbers listed for units are unusually running the purifier on top speed (unless they break it down which some manufacturers do on their websites). The only reason this matters is because a lot of times running purifiers on top speed means they are very loud. I have been very happy with the performance of my Levoit purifiers and they are much quieter even at top speed than my Coway Mighty units. Smart Air also makes excellent units, but they are a smaller manufacturer and it’s harder to get replacement filters. Also, do not trust the onboard pollution monitors to tell you your air quality. Invest in a separate monitor. I like the ones from Temtop. They are good and not too expensive. That way you can run the units on the first or second setting and only turn them up when the monitor shows you need to do so.

Levoit Vital 200 or Coway Airmega for the 16x10. All the others you listed are too small for that square footage. The Levoit is quieter if that’s important to you. If you have a bedroom that is close to double that, you either need two of same unit or a much larger unit (like the Levoit core 600) to clean the bigger room.

Coway and BlueAir are great. Make sure it says "True HEPA," unless you build a corsi-rosenthal box Levoit ones aren't always true hepa.

I have a Conway Airmega for my chicken brooder (chickens create a ton of dust as they grow, and they have to be inside for a few weeks cause they don’t have feathers yet) and it really cuts down on the dust.

I have 1 Conway AirMega ($170 ea) in each room that runs on med 24/7 365. Prior to the air purifiers the kids n wife would always have allergies n congestion/cough for what seemed like year round. My wife would have to pop Benadryl till it knocked her out. Slowly I started putting the air purifiers in each room, vacuuming the pre filter every time we vacuum the floors and they’ve gotten so much better since then. It’s been several years at this point. They still have the allergy fits every once n a while but it’s a lot less frequent. It’s not the prettiest solution to have one in every room, but for us I think it’s been worth the ongoing expense as the filters aren’t particularly cheap ($34 for 2). I’ve done a few other things that probably helped too. I swapped out the 1 inch filter return registers for 4 inch returns. I get 4 inch merv 13s from AprilAire. And I also started vacuuming with a true hepa vacuum.

I love my Coway AirMega! We’ve had it for a few years now and any time we have strong cooking smells or if I spray some hairspray, it kicks into gear and I can tell it’s working! Can’t speak to the longevity/BIFL just yet but I’ve been happy thus far and it seems like it’s great quality. I also buy their name brand filters. *EDIT: brand is “Coway” and phone auto corrected to “Conway”

Yep, we’re a 4 Coway household here too.

I’ve had Coway AirMegas, Winix, and Whirlpool Whispure, and Coway is by far the best home purifier in my opinion. I have an AirThings air quality monitor and a dust allergy, and these filters make a difference. You do need to clean the Coway prefilter regularly, but it’s easy to do. I didn’t know they sold off market filters so I’ll have to look into that because the filters can be costly.

I have 2 Coway airmegas that are super quiet that I’ve had for nearly 2 years. Do you change your filters regularly? Only one I would not recommend is Winix—I had one of the smaller models and its noise was very inconsistent and it was poorly constructed compared to the Coway Airmega and the Honeywell Whispure (a tiny model).

Buy the Coway air mega it usually goes on sale pretty often. 10/10

If I’d known about Austin Air when I bought my Coway Air Mega and Blue Air, I would’ve definitely picked Austin Air and I may still get one. It’s pricey, but so are Coway and Blue Air when you add up the cumulative price of filters. And, I find I need filter replacements much more often than recommended further increasing the cost.

Coway airmega it's excellent. I have mine going 24 hours a day and it senses everything. It also filters the tiniest particles.

The airmega. You can buy filters specifically for dust. There's 3 different types of filters i believe you can buy, the original and two more alternatives

I got a Coway Airmega because it was highly reviewed on the Wirecutter website after my previous Levoit broke after only a couple years and wasn’t fixable (circuit board inside was fried).

We have two Coway Airmega units, one on either side of the house. They have been on 24/7 for several years now. Maintenance and cleaning are very minimal. Cost is about $150-200, although there are larger units based on how big of an area you need to filter. We are very happy with them! Whichever purifier you choose, I highly recommend you look into one with a replaceable HEPA filter. Other filtration methods just won’t give the same results.

Agreed! And they now offer different filters depending on what is most important to you to filter: one for smoke, one for allergens, etc.

This is the only correct answer. Don’t get air mega aim tho that’s a scam

I have the Coway Airmega and an Austin bedroom machine, and they seem to be equally good. The Austin cost significantly more.

Anecdotally, I have two big Airmegas running in fairly small spaces and I can't tell a difference in air quality between when they've been running and when they haven't. I don't get what the point is.

I have a coway airmega in the middle of a ~1k sq ft apartment. It frequently turns on a higher cycle after we cook on the gas stove down the hall

I have the Coway and had it for the last coupe of years B it I recently switched to the blueair purifier and am very happy. They also happen to look good.

The airmega. The number one pick from wirecutter for years now.

We have a 2500 sq ft home so we have several air purifiers. I went off wirecutter’s list and got Coway Airmega for the rooms with higher ceilings and Levoit for the kid rooms and office (where the litter box is). We have had them for a year and I’m happy with them. They’ve significantly cut down on daycare illness transmission within our household. Instead of all 4 of us getting sick it’s 1 kid and sometimes 1 parent per illness.

The Coway airmega is the best overall imo

I have one. They are legit.

I just recently bought 2 coway airmegas. No smell at all.

huge fan of Coway Airmega. filters last a long time, it has a mesh prescreen you take out and clean every 3 weeks or so, and it's both quiet and has a good CADR. And it's very slim and doesn't take up much space!

Coway airmega gets my vote. Got 2 on amazon since pademic and they've been pretty good by far.

Another vote for Coway Airmega. I’ve had several since 2020 and still going strong.

I've got a Coway airmega in our bedroom, and a BlueAir in my office at work. I love both of them... I'm a therapist and work in an 8'x10' room talking to people for an hour 5-6 hours some days. I think the BlueAir is a big reason why I haven't picked up any of the respiratory stuff some clients have come in with (well, that + vaccines + mindful hand washing/sanitizing). It's also pretty quiet which is important to me. I'm planning on picking up another BlueAir or two for the rest of my house this spring. The pricepoint is kinder than my Coway, and it's much quieter.

I would also say my Coway Airmega is one of the best investments I have ever made. It’s amazing how much it can grab and filter out. They say the filters should last a year, but we have it constantly running in a larger room and probably change the filters every 3-6 months. Closer to 3 when we have the AC wall unit on blast thru the summer. We’ve also had terrible Smokey days from the Canadian wildfires in my area and when I last replaced my filter, it was almost black so it was working hard! 2 years of having it and no issues.

Id say no, proprietary airfilter. I use [https://cowaymega.com/products](https://cowaymega.com/products) and get 3rd party filters to replace it. I also turned it into a fan by using plastic vacuum hose.

Coway Airmega; which model depends on the size of the space. Make sure it has a charcoal filter.

Been running coway airmega 24/7 since 2018. Replace the filter every year and bob's your uncle. 

Can't hear it if you set it to low. 

\+1 Coway Airmega.

Coway has a better reputation than the models Costco carries. Love our Air Mega. Bought directly from Coway at a steep discount. Just have to wait for sales.

Thirding this one!! Our are great

Swear by Coway Airmega - liked it so much I bought another one - personally Iove their aesthetic as well but I consider them better than previous levoits and Winix - wait for a special offer is my advice 

I picked up a coway airmega during the Smokey season last year and let it run in the living room. It does a pretty good job of keeping the dust, cooking odor and old house smell to a minimum.

The sensors are amazing. The review on Amazon sold me " my dog farted and it instantly kicked on and I never smell them anymore" Yes whenever I cook or smoke they instantly kick on and work really well.

Second the coway. They are worth the price. Given OP's budget, looking on ebay or facebook marketplace for a used one might be a good first step. Buy new filters for it if you get it used.

Can highly recommend Coway Airmega. We have 3 of them for the same reason. We've had them for a few years and regularly replace the filters, so haven't done recent research to see if there's anything better out there.

As someone moderately allergic to cats and SUPER allergic to dust. I'm allergic to most people's cats because they are silly lil guys who love to find tiny spaces that are hard for humans to dust well. We have two Coway Airmega air purifiers to help minimize dust buildup and deep vacuum regularly with a big kid vacuum to manage dust and floof. The Purina Live Clear allergy reducing cat food 100% works. We have a friend who is allergic to cats (like myself) she had minimal symptoms while at our home for hours. She hadn't taken any allergy meds that day. I still take a Zyrtec every night and generally experience little to no symptoms despite my void floof believing she is a feather duster and rolling on the floor.

I really like the Levoit. It’s super quiet on the lowest setting and you can turn the lights off. My husband is a bozo who needs white noise to sleep so he always turns it up to its highest setting and then doesn’t turn the lights off. We have a coway airmega for our living area but I prefer the way the Levoit looks and my older son kept messing with the coway and it got stuck on a setting so I can’t turn it up or down. ETA I also have a roomba because I am allergic to dogs but my dog is my favorite child and I let him sleep on my bed during the day.

I've been using a Coway Airmega for 3 years now. No complaints besides I don't like the look as much as I thought I would. Keep it in my bedroom because that's where I spend the most consecutive time and also it's not far from an HVAC intake. Having 1 was a bit undersized for my house so at first it seemed to run on medium and high more often (I almost always keep it on Auto). When the pre-filter gets clogged you'll notice it will randomly run on high. Easy to clean and change filters. I've been buying the filters from a 3rd party.

I did tons of research and also got the Coway, been very happy with it!

I have a Coway Airmega and it changed everything for me. My budget was only $200 and you can buy it for less than that easily. Dust, pollen, pet allergies, and cooking fumes are all big problems in my near-century home. I ordered replacement filters from Amazon. I do move it from room to room if I am doing a big project or cooking something which will smoke (no built-in hood). I keep it in my sleeping room the rest of the time. For something inexpensive I have been tremendously happy. If I had a budget of $500, I’d just buy more of these! It definitely cleans cooking odors/smoke no matter what room of my house it’s in, but I like to clear the kitchen air quickly for my own sake.

Coway Airmega looks like a solid pick, especially as it’s clearing out musty smells and reducing allergens while adding that cool breeze feature. I’ve run a few models non-stop in rooms with high humidity, and once they started picking up those subtle odors, I knew I was onto something. I’ve tried some models from Blueair and Medify before, but ConsumerRating is what I ended up trusting because it lined up features like filter life and energy efficiency to my needs. Coway seems to hit that balance of performance and reliability, which is exactly what I’m after.

Definitely the Coway Airmega. It’s sleek, portable and relatively quiet compared to some of the alternatives. You can find some good options [in this thread](https://www.reddit.com/r/productbible/comments/1lj3367/the_best_air_purifiers/)

Absolutely necessary these days. I bought a Coway airmega last year because of the terrible dust from the incessant roadwork. There's a noticeable difference and most importantly, my daughter sleeps better. No regrets

I recommend the Coway Airmegas. To be effective, it will need to run at full blast. Get one with a high CADR or pick up multiples.

I vote for Coway Airmega. I have 3 of them and they’re great

We bought an Airmega four years ago (the last big wildfire year in California's bay area) and it's been a terrific purchase. It helped then with that acute problem, but it also helps keep particulates low year round. It's quiet, doesn't take a huge amount of space, and it makes a noticeable difference in the main living areas of our home (I don't expect it to work in bedrooms at the other end of the house). Do recommend, but the Coway app is pretty crappy.

The Coway airmega is the best imo. You can find some good options [in this thread](https://www.reddit.com/user/Unable-Treacle-9384/comments/1n9p2ve/the_best_air_purifiers/)

I own a Coway Airmega, BlueAir 311 Auto, and a Dyson PureCool. Coway is for the main living room/kitchen, BlueAir for kids rom, and Dyson for our bedroom. Overall the Coway is my favorite. It’s a beast and has a low cost of annual maintenance. Strongly recommend.

I have 4 Coway AirMegas in my house they’re great

I like this one too. It’s easier to maintain than corsi rosenthal boxes and is less noisy.

I have two large Coway Airmegas at home, a Levoit mini at work, and a portable QT3. I use all heavily to make indoor air safer to breathe - removing particulate matter (the most harmful part of breathing wildfire smoke) including airborne viruses. Note that air purifiers don’t remove gases like CO2 from the air and I find when CO2 gets high I will get migraines. Ventilation like opening a window is the solution to CO2 buildup, which is hard when the outdoor air is full of smoke — this is where having an air purifier can make a big difference.

I love my coway airmega.

I tried a Dyson TP07 once, but it felt pricey for my budget, so I leaned toward Coway Airmega because it handles pet hair and dust pretty nicely.

I have a Coway Airmega at home, and it handles smoke and pet dander well without getting too loud.

Just chiming in to say we’ve had a Coway Airmega running continuously 24/7 for the last 6 years and we LOVE IT.

we went with wirecutters top pick and like it; Coway Airmega no reason it needs to be smart, just does its sensing and we let it do it's thing. [https://www.nytimes.com/wirecutter/reviews/best-air-purifier/](https://www.nytimes.com/wirecutter/reviews/best-air-purifier/)

I got a Coway AirMega because my apartment used to smell like my stinky chihuahua no matter what I did, and the smell is gone. Like when I come back to my apartment and open the door, instead of being like "wow, that is what I've been noseblind to?!" it smells the same as the hallway. (Also really helps my dust mite allergy)

We're so happy with our 2 Coway Airmega for each bedroom.

We use Coway Airmega air purifiers and we like them. I think they have a bunch of options for design and size.

Me too! I’ve tried the fancier copay’s but this one is the best for the money. Filters are reasonable and it has good power to circulate air. 

I love the Coway Airmega! I run it all day in the living room. Thinking about a small one fit the bedroom too.

First thing I want to say and it's important. The most important thing you need to know is that the air purifier has got to have true HEPA that is not an option ... 3m/filtrete is a joke of a purifier. They are terrible and do not last. biggest problem you have with their air purifiers are they are not sealed purifiers. There is a lot of dust that gets through other places and bypasses the filter in the unit and then what happens is it collects after the output vent so you will eventually start seeing dust there. Another is their filter cost. It's insane. if you look at their filter replacement schedule, it says the filter lasts 12 months used six hours a day.... air purifier are supposed to run 24/7 to have full effect so if you run it 24 seven that’s every three months their filters are also small... but I personally recommend and have used the past is these two for your size room are these I'll link. you get an air purifier that is going to be more powerful in your price range and will last for starters... There’s a reason why you want something with a higher CADR is because it will clean the air more frequently in that room and clean it better. You will get more air changes per hour basically and that’s a good thing. Also, you’re not gonna have dust getting past your filters and leaking out of the top of collecting everywhere else. You will also get a true 12 month filter when you run it 24/7. It comes with a TRUE HEPA and four replacement carbon filters. One of them will even include a additional year of filters if not both of them out of the box. The Coway Airmega is also another amazing air purifier for the price, however the filter costs have you replacing filters every 3 or 4 months with full use. Alen is also expensive from the get go but filters are annual. I have used these Winx purifiers in the past and I love them the plasmawave can be turned on or off I'd it's a concern but it doesn't produce ozone. I am just linking site so you can get all the information on them however I don’t know if you have a Costco membership or they still sell them or not but it was a great place to get these at an even cheaper price. https://www.winixamerica.com/product/c535/?_gl=1*1v4e0th*_up*MQ..&gclid=CjwKCAjwwLO_BhB2EiwAx2e-35mFNXJgc1BeCOGMGegBQ-An_KwmCD6L29mTNy-0yyIBkVrET2C_jhoC034QAvD_BwE https://www.winixamerica.com/product/c545/?_gl=1*u8q5cp*_up*MQ..&gclid=CjwKCAjwwLO_BhB2EiwAx2e-35mFNXJgc1BeCOGMGegBQ-An_KwmCD6L29mTNy-0yyIBkVrET2C_jhoC034QAvD_BwE

I like the Coway AirMega

I followed the Wirecutter recommendation and have a Coway Airmega. Two technically, one for our room and one for the baby's room. My allergies are a lot better after using them. My only gripe is that the first one we got makes a slight knocking noise sometimes, like it's just a bit out of balance. Usually if I turn it off, let it sit for a minute, and turn it back on again it goes away, but it absolutely drove me nuts when I was trying to sleep. I can't hear it over the white noise machine we use now though.

My seasonal allergies got a lot better when I started using an air filter in the bedroom, so I would assume it works similarly on pets. It's horrifying how much dust it pulls out of the air. I have a Coway Airmega, mostly because that's what Wirecutter recommended. I buy the off-brand filters to save money though.

We've been happy with Coway airmega (one for kitchen, one for bedroom).

Wirecutter recommended the Coway Airmega. I got 2, one for the living room and one for the main bedroom. They have a sensor and cycle higher when there’s more particulates in the air. It has a prefilled and a main filter (that you change only once a year). It has an indicator light to tell you when to clean/change. Here’s the wirecutter piece: https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

These. I raise pet pigeons (very very dusty) in my house and these are what I use.

so you need specifically, a HEPA filter - Austin Air makes a terrific one. So does Coway - the AirMega

I'm sorry the Coway has what now? Pesticides? I finally bit the bullet and purchased one of the airmegas and I've been happy with it (the new plastic smell lasted a day but other than that) so that's kinda concerning....

For what its worth, NY Times Wirecutter blog tested a bunch and ranked the Coway Air Mega as the best option. I bought one and am happy with it. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

Coway Air Mega's are great. Blueair's larger units are equally great - with both DO not buy their filters directly from them - way overpriced - Amazon has generic equivalents that I have been using and have performed great (have air testers in home).

budget budget, build a corsi-rosenthal  otherwise, get a coway airmega. it's a little pricier than some but it has a carbon filter which is great for smells. prefilter catches a lot and saves wear and tear on the hepa panel

Coway Airmega. Consistently high marks and top recommendation by NYT's Wirecutter magazine (which does product testing). Not cheap but super quiet and efficient.

Is there enough ventilation overall? Opening windows in the winter will dry out the interior air but a fan or air purifier is just recirculating the air already in the room. I recently got an Inkbird CO2 sensor to see when it's getting stuffy. I did a DIY hack turning a 自然換気口 (passive air inlet vent) into a powered intake fan that has a PM filter. The models were basically the same size so it was an easy swap. Then I ran an extension cable to an outlet. For air purifiers I use Airmega Coway as the filters are robust. I don't use humidifiers due to condensation risk from poor construction (less of an issue in concrete mansion).

Stick to basics- all you need is a good filter with a fan for PM 2.5. Thicker ones last longer before replacement. Some include additional charcoal/ carbon filters for VOCs and odors. Also try to get a thick/robust one of those as a cheap one I had just got saturated very quickly and ended up releasing smells rather than capturing them. Personally I have a few Coway Airmegas and retired a basic Iris Ohyama one. I also got air intake fans with PM filters so the air coming into the place is cleaner as well. I retrofitted a passive exhaust port into an active air intake as they're about the same size.

I've had a Coway airmega going 24/7 for six years that hasn't developed any noise problems

A Coway AirMega in the classroom was how I survived a couple bad wildfire years. It made an enormous difference.

Noisy on the quick clean burst mode where you tell it to briefly run as hard as possible. Moderate on high. Not noticeable at all under most circumstances.

Second the coway airmega- we use it for our kid's room, but have it on a set setting (rather than the auto setting) because when it would turn on to max air purifier it gets pretty loud.

After pursuing BIFL I decided to pick one up as well. I have two kids with seasonal allergies and this thing has been amazing!!!

Second Coway.

Agree. Our Coway Airmega does a great job, and has an "economy auto" mode you can just leave it on all the time. And if you remove and brush pet hair off the prefilter once in a while, your filters should last a long time.

I got the airmega on Black Friday a few years ago and I’ve been really happy with it. We don’t get a lot of dust anymore and it really seems to help with kitty litter dust and such. Last year there were wildfires nearby and the airmega kicked itself into high gear (I keep it on auto), so I do really trust that it’s actually doing something.

The Coway Mega is fantastic for dust, pet dander, woodsmoke. Had mine for a year now.

This one is kinda meh. Get a Coway Airmega instead

I've got a Coway AirMega in the LR and it's great. In the master BR I've got a Levoit Vital 100 which someone gifted to me and it works well enough. I have a Levoit Core 300 in the smaller bedroom; the space is within the specs but it feels a little small if I need to keep it running on medium... a larger unit running on low might be better. I think they say the 300 is also the most expensive to run, almost 2x the Coway given the CFM.

My Coway Airmega detects odors very quickly and automatically speeds up the fan.

We have a Levoit Everest-air by our grey’s cage, and a couple of Coway Airmegas in each bedroom. I would say an air purifier is mandatory for your health if you own a dusty bird like a grey. Always turn off the ionizer (or get one without it A prefilter that is removable for cleaning is super handy. If you keep it washed (or vacuumed) your air filter lasts so much longer. It’s crazy the amount of dust that collects on the prefilters!

I have these, 0 smell and great to put it on eco mode , as it detects poor air quality it automatically switches modes to higher setting and shows it as purple or red and once air is back to being good it goes back to eco mode and shows blue.

I’m a huge anti-viral illness and clean air mindful person and based on my research and cost, I’d recommend the Coway Airmega. The prices can be decent, sleek look, not too loud, and most importantly they have many articles out there recommending them for actually working.

I’m in the uk and got a Coway airmega and it’s great. Did my research and wouldn’t change it. If you reaaaaaaly want to go all in, there’s some guys on yt that build their own using PC fans but it’s a bit overkill

if you ever feel like making your own air filter, check our r/crboxes for some inspiration. I have an coway airmega, a 6 fan cr box from NorthBox, a levoit mini, and one of the tiny ikea air filters. every room gets a different size and type of air filter according to the needs of that room.

It's not Canadian, but CoWay are a Korean company that make their products in China & South Korea. I bought mine from Amazon before I deleted my account in January. They have a Canadian website for direct ordering though. I used it to buy the filters I needed to replace this year. [https://cowaymega.ca](https://cowaymega.ca)

Same, Airmega still strong.
