Coway - Airmega 200

Coway 200M. Small footprint, cheap generic filters, extremely quiet on low which is enough for a medium room.

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.

We have that one and it's sensitive as hell. Our neighbors smoke weed in their bathroom and that sets it off.

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

Absolutely love our Coway Airmega 200M. In fact, will be buying more shortly.

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?

Coway purifiers have an eco mode that turn off when the air is “clean” for like 30 minutes, then will turn back on when it senses the air quality level has worsened. That being said I keep on auto mode which runs 24 x7 and just changes speed when it senses the quality is getting bad.

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

Second Coway. Filters are a little spendy but they work well. You know how most people‘s homes have a unique smell? We don’t have that according to our friends and I think it has to do with the fact that we run two air purifiers, one on each floor of our house. Both have a automatic feature where it senses the particulate in the air and turns up the fan to filter more and then settles back down to idle when there’s less particulate in the air. I never have to think about them other than filter changes.

The 200M and the 230.

How many sq. ft? Coway Airmega 200M or 250. Winix 5500-2. Yes they will help a lot for allergens and odors, as long as you clean the pre-filter weekly, replace the carbon filter every six months, and replace the HEPA filter every year.

I love my Airmega 200's, but they're so loud on high :(

it is a nice white noise, remember to hold the Ionizer button to turn off the light at night :)

i wouldnt choose any of those, i'd go with Coway Airmega 200M or Winix 5500-2 all the way

A different larger Coway has been good for me and cost around$120 iirc, but it stopped working well in one of the three settings after a recent move. Middle setting is running exactly like the lowest now. Lasted over 2 years before that though and I believe it should be under warranty still Can’t comment on winix though

Sorry I don’t have specific information on these models. Lmk if you want more info on the filter I actually do own. Im 95% sure its the air mega 200

I just bought two Coways (100, 200). They seem good so far. One question: they seem always to stay on blue state (good air quality). Does yours cycle through other air quality states and kick on more?

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

That's what I have. But the 200M is identical except in appearance and sometimes it's cheaper (and sometimes not).

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.

I have a Coway Air Mega 200M. Recommend it highly. Got it during Amazon prime sale for a good discount. Prime day is coming up soon - might be worth checking out.

Also, that Coway and maybe another are what the New York Times Wirecutter reviews recommend. They actually buy products and test them long term.

if you’re looking for something a bit smaller and affordable i stand by my coway airmega 200M, only $200 and is super super quiet on 1 and 2, 3 not so much but 3 moves TONS of air, very affordable replacement HEPA and carbon filters as well

Hey Costco friends! Just grabbed that sweet Shark MAX deal ($150 with extra filter) and I'm starting to think my unit might be the air purifier equivalent of an overly-optimistic friend. (Razor for scale - it’s big!) According to Shark, my air quality is a perfect 100% ALL DAY LONG. Even when: - My elderly Akita wanders by shedding fur like it's his job (and also pooting pretty non-stop) - I deliberately sprayed Lysol directly in front of it (for science!) Meanwhile, my trusty Coway Airmega 200M goes absolutely bonkers at the slightest disturbance. When the Akita walks by? BEEP! Lysol spray? "I'LL SAVE YOU HUMAN!" The Shark? "100% perfect air, nothing to see here!" 🙄 I did all the obvious stuff - removed the plastic from the filter, checked connections, etc. I also noticed barely any air being pulled INTO the unit (though it does push air out). Anyone else experiencing this with their Shark MAX? Is my unit defective or just incredibly optimistic about my home's air quality?​​​​​​​​​​​​​​​​

https://preview.redd.it/av30ms1tqcne1.jpeg?width=2701&format=pjpg&auto=webp&s=c292b5800214f57f0ff3c5365c9af5afd4674517 Just for comparison, here’s my big guy plopped down in front of my Coway, and it immediately turned purple (the air quality level between blue and red).

That's the answer. Wirecutter's choice for years and years. I tried a few others after my first Airmega and ended up returning them and getting another Airmega.

I’m a fan of the Airmega 200. I have two in a 1200 square-foot house. That washable pre-filter is invaluable.

The coway 200 and 250 are by far the best. Clean them once a month and you'll be shocked what you were breathing. When the sun is low I don't see the shit floating in the air I was always used to. It's just totally clear.

Yes, I like the **Coway Airmega 150** for smaller rooms. I'd say the maximum room size for this model would be 229 sq. ft. with an 8 ft. ceiling, calculated by the Smoke CADR of 153 CFM. The **Coway Airmega 200M** is a good performer for that price. Maximum room size should be 369 sq. ft. with an 8 ft. ceiling based on a Smoke CADR of 246 CFM. However, it appears to be louder at its top speed (55.1 dBA or decibels A-weighted). The **Airmega 200M** also has an ionizer which can be switched on or off. If you have any pet birds, you'll want to keep the ionizer off. This is due to the possibility of a small amount of ozone generation; birds are much more sensitive than humans. Keeping the ionizer off may affect the CADR somewhat, although I don't know by how much. A few studies are concerned ion generation can react to produce byproduct pollutants (typically gases) in the air.

500 sqft is big, especially if you’re talking about trying to reduce cat allergies because their dander is everywhere. If you’re looking at Coway, you’d need at minimum the 200. No ionizers. They produce ozone which is an irritant and pollutant in itself. Don’t know why companies still produce units that use it, but on the coways you can turn it off. While an air purifier can help, you’re going to get a lot more bang for your buck from a bagged vacuum with HEPA filter if you’re not using one currently.

I have a Shark and a coway in my basement pottery studio. They are not right next to each other. I keep them both on medium fan speed and they usually agree with each other. When I have them on low fan speed, the coway reads dirtier air more than the shark. Try leaving it on manual medium fan speed for a day or two and see what it does.

I have the 200 and buy the cheap Hepa filters, but they seem to do the job. Holy shit the coway200 is on sale for $117

Second, we've got 2, they're great. The Airmega 200 is basically the same unit too. Multiple smaller air purifiers tends to work a lot better than single big ones.

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 two Coway Airmegas and a Winix D4. I prefer the Coway. They all make a significant difference with the smoke.

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.

Used these for 3-4 years. Never broke. They do the job but a Conway airmega is significantly quieter and an handle a bigger space, also has air quality monitoring that is super helpful and can be set to automatically increase filtration if air quality is poor. That said Levoit remains an excellent choice if you’re on more of a budget.

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).

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).

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

This is the choice - had mine over a year and still going strong

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

Seconding. Got ours 2020 so can't really vouch for the longevity. We usually keep it on auto... though once in awhile we have to go turn it off when watching TV because it goes into overdrive for no apparent reason-- but this is fairly rare.

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.

I have one. They are legit.

We also have the Coway Airmega. Have one on each floor. They work very well. However, we prefer the replacement filters no direct from Coway- read the reviews on Amazon, but the Coway ones had some issues with plastic smells/making air quality worse. Some type of defect.

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

I have the Coway mega and a taotronics ap-003. I like the taotronics ap-003 more and it cost 85 usd.

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.

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

This. I have a winix 5500, two blue air 411s and two coway airmegas and the coway is my favorite by far.

\+1 Coway Airmega.

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.

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.

Air purifiers aren’t regulated so getting one that has undergone 3rd party testing is important in order to know they do what they claim they do. Coway Airmega does 3rd party testing. The ones that have an ozone setting have it as optional — something you have to turn on to use. We just never use it. Insane to me that they even have those. Yes, ozone is bad for people with asthma. Also bad for pets, especially birds. And probably people generally. I love that my coways automatically rev up in response to detected poor air quality. And they are whisper quiet when just in background mode. We only notice them when the go into high gear — usually when we are cooking. Edit to add: wirecutter still rates coway as a top purifier: https://www.nytimes.com/wirecutter/reviews/best-air-purifier/

I’ve had mine for over 6 years and they’re still going strong. I love them

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.

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.

I don't think those will be effective in such a large open space. For heating and cooling, with what you could spend on a couple of those Dysons, you could get a mini-split heat pump for heating and cooling. As a purifier the BP04 will be okay but you can spend half as much for better performance with a Coway Airmega or Nuwave Oxypure. You could build a Corsi-Rosenthal box for the best performance to price, but DIY isn't for everyone.

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

That’s what we have! My baby is also obsessed with it; not a day goes by that he doesn’t crawl up to it and start poking his little fingers into the holes on the front 😂

I love my coway airmega.

I have several Coway airmega and they are legit wonderful. They have an app so I can set programs for the speed, and report on air quality. I run these full time for years and they still are working great. Ive had several other brands but these are the best.

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.

I have two Coway Airmega that run like absolute champs and have very widely available and affordable filters

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

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

Coways are sold in europe but you need to find them on sale and that only happens once in a while, I was able to get my coway airmega for \~450 eur. Your other options are AEG (currently having lots of discounts) and winix. There is also rowenta, phillips & amazon basic, I personally don't like rowenta so I'd avoid it. If I was looking for a purifier, I'd try to get the AX9, has an insane CADR and costs around 330 eur right now.

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.

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

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/

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

The Coway Airmega is really good. We have three of the larger model.

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).

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

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.

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

Coway Air Mega for the win! It’s big. It’s quiet on low speed. Did I say it’s big? It sucks a vacuum cleaners worth of crap out of my air every three or four months.

This one is kinda meh. Get a Coway Airmega instead

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’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

Coway room aipurifier is amazing. We have it in our bedroom. Though our area is quite clean it does remove dust and fungal odour during winters
