Coway - Airmega 100

Coway 100% \`non-paid spokesperson\`

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.

Love my Coway Airmega 100, I have it on the dresser in my bedroom.

Between those two units definitely go with the Coway. The Winix is in part an ionizing air purifier (The plasmawave thing they advertise) which don't work particularly well and have some issues with VOC generation. See: https://phys.org/news/2021-03-uncovers-safety-air-purifiers.html Coway is a reputable brand that I've not heard anything bad about. Levoit core 300 is a similar unit that you might consider though, slightly larger, slightly higher CADR but they should be pretty similar honestly.

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?

Chiming in - I have a studio down by the port and the Coway is a Dustbuster!

It's pricey, but some people who travel for work use the [AirFanta 3Pro Air Purifier](https://a.co/d/3B7X9DU) since it can be packed into a carry-on bag! I personally use Coway's Airmega 100 for my bedroom and take it with my pretty easily in my backpack for doctor appointments. I would definitely bring it along with me in a backpack or a duffle bag for hotel rooms! It's big enough to actually clean the air of a hotel room a number of times within an hour, while small enough to not be a hassle for me to tote with me!

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

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

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.

I picked up the small Conway Airmega for my bedroom and am pretty happy with it

We have a Coway Airmega in the nursery and absolutely love it. BUT I will say there is a super cheap alternative that is just as good. Buy a 20 inch box fan and a 20 x 20 HEPA air filter. Tape it on the back and it works perfectly! It's just louder. But highly effective, we have multiple of these around the house!

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.

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

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
