I use Coway from Amazon. So far I have the Airmega 100 for my bedroom and an Airmega 150 for the living area. Might get one more for my office at some point. ETA: I have severe allergies and migraines and I have noticed an improvement in both. I wake up with a clear nose and have had way fewer migraines.
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->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?
r/AirPurifiers • can breathe and sleep again (coway review) ->Chiming in - I have a studio down by the port and the Coway is a Dustbuster!
r/askvan • People using air purifiers in single rooms/ condos/ small apartments ->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
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->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
r/BuyItForLife • The Best Air Purifiers? ->Eh, Energy Star rates the Coway Airmega 100 for 169 square feet. How big are the rooms you're staying in? https://www.energystar.gov/productfinder/product/certified-room-air-cleaners/details/2732648 Sadly it's very common for air purifier companies to overinflate their room size coverage. Energy Star and the Association of Home Appliance Manufacturers are great sources for seeing the recommended room size. Even then, the room size is based on the highest fan speed. Sometimes there can be big differences among the different fan speeds.
r/ZeroCovidCommunity • I know this has been asked before, but are air purifiers for travel worthwhile? ->I picked up the small Conway Airmega for my bedroom and am pretty happy with it
r/BuyItForLife • The Best Air Purifiers? ->Coway would be the most reliable in considering Winix (or even Levoit). But I wouldn't recommend the Coway Airmega 100. Per the [AHAM 2/3 rule](https://ahamverifide.org/ahams-air-filtration-standards/) mentioned in the AutoModerator comment, your "adjusted" square footage of 197 sq. ft. requires minimum CADRs of 132 CFM. The Airmega 100's top CADRs are too low. I would recommend the [Coway Airmega 150](https://cowaymega.com/products/airmega-150) or [Coway Airmega 160](https://cowaymega.com/products/airmega-160) instead. If you want to order directly from Coway, use the discount codes **COWAYMEGA10** or **FORYOU10** for an extra 10% off. Keep in mind the CADRs listed apply to the highest airflow speed/setting only. Lower settings have lower CADRs, which reduces cleaning effectiveness.
r/AirPurifiers • (US) Winix C610, Coway Airmega 100, or something else entirely? ->The only smaller air purifier I have is the $200 Conway in my kitchen. Its like a jet engine when on high speed. That's OK when I've burnt something. But there is no way people are running it at that noise level in general use. The smaller the air purifier the more likely that its homeopathic in real use. Also, with a home's ducted HVAC system running, the air cleaner is attempting to clean the whole house.
r/homeassistant • Best Air purifier in 2025? ->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.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->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.
r/BuyItForLife • The REAL best air purifier - I HATE 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.
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->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”
r/BuyItForLife • The Best Air Purifiers? ->Yep, we’re a 4 Coway household here too.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->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.
r/BuyItForLife • The Best Air Purifiers? ->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).
r/BuyItForLife • Air purifier that doesn't develop annoying bearing noises ->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).
r/homeowners • Best Air Purifiers for Pets? ->Buy the Coway air mega it usually goes on sale pretty often. 10/10
r/CleaningTips • Air Purifier sucking dust in my room ->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.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->Coway airmega it's excellent. I have mine going 24 hours a day and it senses everything. It also filters the tiniest particles.
r/AirPurifiers • Air purifier recommendations? ->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
r/AirPurifiers • Air purifier recommendations? ->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).
r/parrots • Any recommendations for air purifiers? Ignore the mess, I’m currently in the middle of a deep clean in my room. ->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.
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->Agreed! And they now offer different filters depending on what is most important to you to filter: one for smoke, one for allergens, etc.
r/BuyItForLife • The Best Air Purifiers? ->This is the only correct answer. Don’t get air mega aim tho that’s a scam
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->I have the Coway Airmega and an Austin bedroom machine, and they seem to be equally good. The Austin cost significantly more.
r/Allergies • Whats the best hepa filter air purifier? ->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.
r/BuyItForLife • I analyzed Reddit data for the 20 most recommended air purifiers (in the past year) ->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
r/AskNYC • Best air purifier for NYC apartment? ->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.
r/AirQuality • What's the best pick of home air purifier that you've ever used for improving indoor air quality? ->The airmega. The number one pick from wirecutter for years now.
r/AirQuality • What's the best pick of home air purifier that you've ever used for improving indoor air quality? ->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.
r/moderatelygranolamoms • What are the best air purifiers for home to enhance indoor air quality currently? ->The Coway airmega is the best overall imo
r/AirQuality • What air purifier is the good/best to get for BEDROOM in today's market? ->I have one. They are legit.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->I just recently bought 2 coway airmegas. No smell at all.
r/AirPurifiers • I’m lost ->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!
r/ZeroCovidCommunity • Best air purifiers for my square footage ->Coway airmega gets my vote. Got 2 on amazon since pademic and they've been pretty good by far.
r/moderatelygranolamoms • What is the best air purifier brand for home you prefer over the others on the market? ->Another vote for Coway Airmega. I’ve had several since 2020 and still going strong.
r/BuyItForLife • Best Air Purifier Brands? ->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.
r/moderatelygranolamoms • What is the best air purifier brand for home you prefer over the others on the market? ->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.
r/buyforlifetips • Best Air Purifiers for Home Use? Recommendations Needed ->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.
r/Costco • Shark air purifier.. good? bad? ->Coway Airmega; which model depends on the size of the space. Make sure it has a charcoal filter.
r/fednews • Air purifier for small office ->Been running coway airmega 24/7 since 2018. Replace the filter every year and bob's your uncle.
r/BuyItForLife • Looking for a high-quality air purifier that's built to last. ->Can't hear it if you set it to low.
r/BuyItForLife • Looking for a high-quality air purifier that's built to last. ->\+1 Coway Airmega.
r/Home • What's the best air purifier for home you've used? Worth it or Scam? ->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.
r/Costco • Need Help Choosing an Air Purifier from Costco—Totally Lost Here! ->Thirding this one!! Our are great
r/Masks4All • The TRULY best air purifier for home to buy currently - The air quality is FULL OF DUST! ->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
r/CleaningTips • What air purifier do you swear by? Trying to cut through the hype. ->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.
r/homeowners • Advice on choosing the best air purifier for home among tons of options available today - Do they really work or are they just a SCAM? ->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.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->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.
r/BuyItForLife • Budget friendly Air Purifier for bedroom ->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.
r/AirPurifiers • Recommended purifiers for wildfire smoke? ->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.
r/Pets • Advice Needed: Partner’s best friend just moved in… and now he’s allergic to my cats!! What do I do?? ->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.
r/AirQuality • What is the best air purifier out there? ->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.
r/moderatelygranolamoms • What are the Best Air Purifier for Allergies? ->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.
r/homeowners • The Best Air Purifiers for Pets Available Now? ->I did tons of research and also got the Coway, been very happy with it!
r/homeowners • To kind homeowners, the best air purifier? What do you use for home? ->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.
r/homeowners • To kind homeowners, the best air purifier? What do you use for home? ->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.
r/BuyItForLife • What are the Best Air Purifier in 2025? ->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/)
r/AirQuality • What air purifier is the good/best to get for BEDROOM in today's market? ->I have three too. They've run 24/7 for years without an issue. Third party filters work fine and are half the price.
r/BuyItForLife • 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
r/mumbai • Air quality in Mumbai! Is it necessary to buy air purifier? ->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.
r/AirPurifiers • Best air purifier for apartments affected by wildfires? ->I vote for Coway Airmega. I have 3 of them and they’re great
r/BuyItForLife • The Best Air Purifiers? ->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.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->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/)
r/BuyItForLife • Good air purifier to use against alergens/dust. ->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.
r/AskNYC • Best air purifier for NYC apartment? ->I have 4 Coway AirMegas in my house they’re great
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->I like this one too. It’s easier to maintain than corsi rosenthal boxes and is less noisy.
r/Masks4All • The TRULY best air purifier for home to buy currently - The air quality is FULL OF DUST! ->Same here! Got one for each room last year, and very satisfied with it so far.
r/homeowners • For those who suffer from allergies, which air purifier really works well in your opinion? ->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.
r/homeoffice • Best air purifier ->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.
r/homeowners • What's the best air purifier for home you swear is really worth buying today? ->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.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->I love my coway airmega.
r/moderatelygranolamoms • Are air purifiers worth buying for pets? Which options would be the best you've tried? ->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.
r/moderatelygranolamoms • What are the best air purifiers that you'll recommend for home currently? ->I have a Coway Airmega at home, and it handles smoke and pet dander well without getting too loud.
r/BuyItForLife • The Best Air Purifiers? ->Just chiming in to say we’ve had a Coway Airmega running continuously 24/7 for the last 6 years and we LOVE IT.
r/BuyItForLife • I analyzed Reddit data for the 20 most recommended air purifiers (in the past year) ->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/)
r/SmartThings • Looking for 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)
r/BuyItForLife • Budget friendly Air Purifier for bedroom ->We're so happy with our 2 Coway Airmega for each bedroom.
r/ZeroCovidCommunity • What are the best air purifier brands for home use in terms of air filter quality and other specs in your opinion? ->We use Coway Airmega air purifiers and we like them. I think they have a bunch of options for design and size.
r/Minneapolis • Wildfire smoke air filters? ->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.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->I love the Coway Airmega! I run it all day in the living room. Thinking about a small one fit the bedroom too.
r/moderatelygranolamoms • What are the best air purifiers for home to enhance indoor air quality currently? ->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
r/AirPurifiers • Need help choosing an air purifier for allergies ->I like the Coway AirMega
r/moderatelygranolamoms • What is the best HEPA home air purifier that's actually worked well in your opinion? ->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.
r/moderatelygranolamoms • What are the best air purifiers for home to enhance indoor air quality currently? ->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.
r/moderatelygranolamoms • What are the Best Air Purifiers for Pets? Do you notice any clear difference when using them? ->We've been happy with Coway airmega (one for kitchen, one for bedroom).
r/moderatelygranolamoms • What is the best air purifier brand for home you prefer over the others on the market? ->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/
r/Home • Your top choices when it comes to the best Home Air Purifiers? ->These. I raise pet pigeons (very very dusty) in my house and these are what I use.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->so you need specifically, a HEPA filter - Austin Air makes a terrific one. So does Coway - the AirMega
r/AirQuality • i feel bad all the time in my new apartment (no central air). took a measurement today and this is what it was. what can i do? is this liveable? i have asthma so I'm sensitive to air quality ->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....
r/AirPurifiers • I’m lost ->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/
r/AskLosAngeles • Air purifier suggestions!? ->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).
r/homeowners • For those who suffer from allergies, which air purifier really works well in your opinion? ->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
r/AirPurifiers • air purifiers on a budget! ->Coway Airmega. Consistently high marks and top recommendation by NYT's Wirecutter magazine (which does product testing). Not cheap but super quiet and efficient.
r/CleaningTips • What air purifier do you swear by? Trying to cut through the hype. ->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).
r/japanresidents • Air humidifier and purifier frustrations - Any recommendations? ->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.
r/japanlife • Any Airdog air purifier owners living in Japan? Is it really worth the high price? ->I've had a Coway airmega going 24/7 for six years that hasn't developed any noise problems
r/BuyItForLife • Air purifier that doesn't develop annoying bearing noises ->A Coway AirMega in the classroom was how I survived a couple bad wildfire years. It made an enormous difference.
r/Teachers • Air Purifier ->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.
r/Teachers • Air Purifier ->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.
r/moderatelygranolamoms • What are the best air purifiers for home to enhance indoor air quality currently? ->After pursuing BIFL I decided to pick one up as well. I have two kids with seasonal allergies and this thing has been amazing!!!
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->Second Coway.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->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.
r/BuyItForLife • What are the Best Air Purifier in 2025? ->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.
r/parrots • Air purifier recommendations? (Preferably available on Amazon obviously need to be bird safe!) ->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.
r/homeowners • The Best Air Purifiers for Pets Available Now? ->The Coway Mega is fantastic for dust, pet dander, woodsmoke. Had mine for a year now.
r/BuyItForLife • Mega allergy sufferer, what's the best damn industrial air purifier I can possibly get? I just need it for a small apartment, but I don't care, I suffer so badly that I'll blow $1k if I have to clean every molecule from my sleeping environment. ->This one is kinda meh. Get a Coway Airmega instead
r/Costco • Any thoughts on pictured air purifier? ->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.
r/AirPurifiers • I’m lost ->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.
r/AirPurifiers • Can you help me choose between these 5 air purifiers for 2 bedrooms? Mainly allergies, smell and air quality ->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.
r/AskNYC • Best air purifier for NYC apartment? ->My Coway Airmega detects odors very quickly and automatically speeds up the fan.
r/AirPurifiers • Best air purifier for litterbox odor/pets in a 200-250 square feet room $200 max budget? ->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!
r/AfricanGrey • Air purifier experience ->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.
r/AirPurifiers • I’m lost ->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.
r/askvan • People using air purifiers in single rooms/ condos/ small apartments ->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
r/BuyItForLife • In need of an air purifier for an open living room that is low energy. ->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.
r/ZeroCovidCommunity • Room air purifiers ->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)
r/BuyCanadian • Best Canadian Air Purifier? ->Same, Airmega still strong.
