Coway - Airmega 250

You have an old car that's awesome! I also have an old car. What kind of car do you have? I drive a 94 Mustang Cobra. I have a coway Air Mega 250, and I have been happy with it.

I have a coway airmega 250. I have been happy with it.

You need to check the manual for the AQI sensor sensitivity settings. It is probably set to high sensitivity. Need to change that. So, it will only change colour over a high aqi deviation. Had that issue with AirMega 250

The Coway Airmega 250 and 250S are on sale for under $250.

The Coway Airmega 250 and 250S are on sale for under $250.

I’m immunocompromised and always have an air purifier (Coway AirMega 150) running next to my lectern. It’s nearly silent on the lowest setting. I also have a larger one at home (250?) that is EXTREMELY loud, so I wouldn’t recommend a big one. The building I teach in is pretty modern, so I have to assume that the ventilation is quite good even though my classroom doesn’t have any exterior windows. I’ve been told many times I’m quiet/soft spoken (despite feeling like I’m always yelling), so masking while teaching is out of the question for me. I also tell my students on the first day of class that I am immunocompromised and therefore that if I do get sick, I am likely to get very sick and be gone for several weeks (sometimes I include the fact that my body literally cannot make antibodies, which is super fun). This info seems to stick with them, as I’ve had many students email me to let me know they’re sick and staying home because they remembered what I said. I am also pleasantly surprised that most students wear a mask for a few days when they return. I never mention masks at all and have never asked for anyone to wear them, fwiw. I also have a couple bottles of hand sanitizer in the room and use it very, very frequently (literally any time I touch a shared surface). I follow the same precautions in my office. I’ve had COVID three times, and two of the three times it was during the summer (I don’t teach summers). The third time I’m 99% sure I got it at a concert. Your mileage may vary, but I feel like my strategies work fine for me and at the very least give me peace of mind.

You seem to understand what you need. You took into account your high ceilings which is good. Most CADR is measured with the average 8 foot ceiling so your numbers are higher which you already posted. Keep in mind CADR is measured at maximum fan speed, so you’ll want a purifier that can deliver CADR over your actual square footage so that way you can run the units at medium speed. Some people run them at max, but most do medium since it’s a tolerable noise level. Since you’ve been on this sub, I assume you know that purifiers are only good to clean the air in the room they’re placed in. They don’t clean air in other rooms because of the way air moves around homes, which isn’t much. I’m no expert and I’m kinda new to purifiers too and there’s much more knowledgeable people on this sub. I can’t speak to other brands, but I like my Coway Airmega 250 that I got. It says it covers up to 930 sq. Ft. And 2 air changes per hour in that amount of space at max speed. I find that the unit may be a little small for the area I’m cleaning which is the living room and kitchen. I keep it positioned between the 2 and it takes longer to clean the air in each room positioned like that vs. being placed in the actual room, but it gets the job done I feel like and I’m happy with it. Not sure how much help that was, but I would look at the Coway Airmega series. Pricy, but good units. I haven’t tried any others but I know air doctor is good but very expensive. Good luck

Air purifiers can’t go into other rooms generally speaking, so you will need multiple purifiers. Whatever room they’re in you can expect the air to be exchanged regularly, but even with a good one in the hallway it would barley exchange the air in the rooms because of the way air circulation works. Having fans going in rooms and pushing air into the hallway to get purified is one solution, but the best solution will be multiple air purifiers. If I were you, I’d get a purifier for the computer room and bedroom. I have a pretty small house and I have a Coway Airmega 250 and I love it. I keep it between my living room and kitchen and it does a good job of purifying the air in those rooms. Sometimes I take it to my bedroom at night. It’s kinda heavy but it’s easy enough to move

I have a AirMega 250 and another cheaper unit in my "cat room" (opposite side of house). I prefer the AirMega in bedroom not as light polluting. I change the filter once a year and its around $80 for the unit.

I have both Dyson tp10 and Coway air mega 250, and coway is MUCH better than Dyson, and it's literally half the price.

You need to realise that Coway will be red over the aqi of 80. It is probably known as the best air purifier company in the world along with Blue Air.

I have 3x Coway AirMega 250 units (one in each bedroom) and have not had any chemical smell issues at all FWIW. I’m guessing it can depend on the people, as some are more sensitive to certain smells than others.

Coway is really good. Been using that for a while now.

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 coway airmega 250 - for reference I live in a 750 sq ft apartment with 2 cats. I’ve found all of their models to be really user-friendly and have had it for almost a year without having to replace the larger filter. It is very responsive to current levels (after stove cooking, etc) and the pre filter catches a lot of visible dust. I’d wait for a good deal like Black Friday if you can

Do have the Coway 250 as an option? I got one for $250 open box or refurbished on Amazon. It’s amazing. The sound it makes is very pleasant and it’s easy to clean, and aesthetic. The Coway or 240 is also a good choice and comes in white. The Winix 5500-2 or C535/C545 is also a solid choice and a bit more affordable. I believe Costco has good deals on the C545. Lastly, you could check local marketplaces. I got some Winix, and Blue Air purifiers (the 203 slim, 403, and 503) for a great price.

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!

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

We have a Coway Air Mega 250 on each floor of our duplex. It has a HEPA filter and helps remove odors too. There is an air quality sensor. I like how quiet they are. Because you’re specifically worried about pet hair/dander, I would also make sure you have a HEPA vacuum — focus on mopping/vacuuming and washing/brushing the pets weekly. I have a very furry dog and my daughter ends up covered in hair when she’s crawling around so I can relate 😂

I also have this in an apartment with two cats and it works really well.

I've had a coway airmega 250s for 3 years and haven't had any problems.

We have four Coway 250S. We have them running basically 24/7, and use the scheduler to ramp them up over night. Love them.

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.

We generally don't advise a combined humidifier and air purifier unit. Pushing very moist air over mechanical filtration is not advised, as it could degrade or cause microbial growth on the filter media. Levoit wasn't even mentioned in the [old buying guide](https://www.reddit.com/r/AirPurifiers/comments/w4uhgf/air_purifier_buying_guide_read_before_asking/). We (or really rather one of the moderators here) tend not to recommend cylindrical air purifiers for particulates. This is due to a concern that cylindrical or otherwise round units may have underpowered motors which must operate at higher speeds to provide adequate air flow. This can lead to motor burnout or a shortened purifier lifespan. Additionally, these units tend to have integrated pre-filters which are not ideal. A separate permanent pre-filter is best generally, as they're easier to clean and there's less risk of damaging the HEPA media. I would say Coway has better build quality than Levoit or Winix. If you're treating for dust storms, I would increase the CADRs beyond the minimum 2/3 of a room's area (with an 8 ft. ceiling assumed). You can have all the smart features you listed if you choose a Coway purifier with an "S" appended to the model name. Most Coways look pretty nice IMO. None of these units have much activated carbon for odors, but then again it's not a primary concern for you. For your bedroom, a suitable model would be the [Coway Airmega 250S](https://cowaymega.com/products/airmega-250s). Your living room is a bit trickier if it's about 3x size of your bedroom (living room: 576 sq. ft.). Minimum CADRs here should be 384 CFM, but should probably be at least 400 CFM - 500 CFM for dust storms. Unfortunately there's no one Coway model to fit the bill. Both the [Coway Airmega 300S](https://cowaymega.com/products/airmega-300s) and [Airmega 400S](https://cowaymega.com/products/airmega-400s) have lower CADRs. In this case, you need two purifiers in the living room potentially (mix or match the models mentioned above).

See **Rule 4**, which is repeated in the AutoModerator comment. What is the length x width x height of your room? Coway is definitely better in terms of build quality. But the Xiaomi Smart Air Purifier 4 Lite has a higher particulate Clean Air Delivery Rate (CADR). CADRs are determined in part by room volume.

600 AQI!? That is incredibly high. Is the primary pollutant PM2.5? The larger the filter, the greater the longevity (airflow speed also matters of course). You would need to buy multiple Coway purifiers per room. You didn't list a budget per **Rule 4**, so I don't know what you want to spend. I might have a Coway Airmega 250 in the bedroom. And I would have another Coway Airmega 250 in the living room plus a Coway Airmega 150. If you want to spend less, you could buy two [Philips AC3220/60 purifiers](https://www.amazon.in/PHILIPS-Purifier-AC3220-60-Portable/dp/B0DNK11RY1/): one for the bedroom and one for the living room.

If your AQI is frequently poor, this means you need far more powerful purifiers than what's normally recommended per room volume. We often recommend two types of air purifier if you have high particulate matter *and* gaseous pollution levels. In order to capture particulates, you need high airflows and mechanical filters with significant surface area. Purifiers like these have little sorbent media for gases/vapors/odors. Sorbent media = activated carbon, activated alumina, or synthetic zeolites. For gases, you need high weights of sorbent media. Depending on which gases are present, modified (e.g., impregnated or wet-mixed) sorbents may be necessary. Plain/chemically untreated sorbents do not have high removal capacities for all gaseous species. For a particulates purifier, I would find the highest Clean Air Delivery Rate (CADR) you can afford. Coway is usually the first recommendation due to build quality. But you'll pay more money. I'm unsure if the [Coway Airmega 250](https://cowayindia.in/coway-airmega-250) would be enough for a 14' x 15' room in very bad AQI scenarios. You may want to consider the [Philips PureProtect Pro 4200 Series (AC4221/61)](https://www.philips.co.in/c-p/AC4221_61/pureprotect-pro-4200-series), as it has a higher top CADR than Coway. Keep in mind the listed CADRs for these purifiers applies to the highest airflow speed/setting only. Lower settings have lower CADRs, which reduces cleaning effectiveness. For gases/vapors/odors, I don't have any suggestions - sorry. Normally IQAir GC or GCX series purifiers are available in many parts of the world, but I don't see these on Amazon India. **Other suggestions** I would invest in a bagged vacuum with a HEPA exhaust filter if you don't own one already. (An example brand would be [Miele](https://www.miele.in/domestic/cylinder-vacuum-cleaners-1780.htm).) This can help with coarse particulates.

I bought an [Airmega Coway](https://a.co/d/3JKemQm) last year and I'd give it a recommendation if it's in your budget. I'm pretty sensitive to the smoke and tend to start coughing the moment I crack a window open. If I seal up my place and let this run, I don't feel any effects from the smoke at all really. And it doesn't hurt to get a unit rated for a bit more space than you're trying to filter so it doesn't have to work at full power when the air is bad. Also bonus points because the automatic mode actually seems to work pretty well for knowing when to crank up, and it automatically goes to low power mode at night and is whisper quiet. I did have to dampen a couple rattles in the top grill to get it dialed in though.

Coway 250s. Just got one on sale. Lowest price it’s been for awhile

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.

Coway models from 250 upwards (250/300/400) have child lock. I don't recommend the 350/450 because they are round, but the others should suit your needs.

My Airmega 250 is … excellent. If you have the correct sized room it’s a well built and - stylish, after a fashion (that fashion is “1960’s Radio”) purifier with good noise levels and exceptional performance. It’s been trucking along since the day it was made available (I got one on release special sale at Amazon) and I anticipate it. Continuing to run for years yet. It cleans the air in my master suite.

I have no evidence that Air oasis is recommended because of kickbacks, but it is the most expensive unit and employs shady marketing practices as well as “snake oil” technology such as UV lights, silver, and whatnot. Coway is just fine for mold. Excellent in fact. Get one for the living area and one for the bedroom. If the bedroom is small you could get a Coway 150, and a 250 for the main living space.

Generally I recommend Coway. Unless you have a ton of money it’s the best bang for the buck. Size it appropriately. The 250 is a great unit.

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.

That's a possibility, if you're concerned about the toxins then H13 is advisable. Be aware that there are NO consumer-grade H14 purifiers, so H13 is pretty much as high as they go. I recommend something with decent foam seals on the HEPA filter, like for instance the Coway 250 (and 150) have foam around the filter which prevents particulates from going around the media.

Clean Air Kits isn’t HEPA. Does that matter? Maybe or maybe not. But it’s very specifically NOT HEPA. That said, most of Coway’s lineup has no ionizer. The 250/300/400 are excellent machines. (Avoid 350 and 450 as they are round…)

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).

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

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 

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.

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.

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/)

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

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.

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

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 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.

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 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.

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.

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.
