Coway - Airmega 250

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 250 is the best one you listed but if you can splurge for a 300 or 400 from Coway that would be even better. That's a large room you're trying to clean the air for.

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.

Coway airmega 250 that I love 💕

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 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 😂

You have atleast 3 really good options in Australia. I am in NZ and have mix of Smart Air SA600, Blast and Blast Mini covering entire home. You need lots of charcoal in air purifier to remove smells. Ozone is bad IMO. Aussie made with around 5.5kg charcoal is Inova air purifiers https://inovaairpurifiers.com.au Smartair - Blast has 1.1kg charcoal which is there biggest model https://www.bsthealth.com.au/air-purification/air-purifiers.html Coway Airmega 250 or 400 https://www.amazon.com.au/s?k=coway+air+mega&crid=33RTBMZJEGJMB&sprefix=coway+air+mega+%2Caps%2C265&ref=nb_sb_noss_2 You need to look at CADR and how many air changes does the air purifier offers for the space it’s going to be covering. At minimum it’s good to have 5 air changes. The Medify is 4 air changes covering a very small area and it’s also very loud.

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).

I have this one in my son's room and I'm happy too. I also have the 250, 300 and 400. I'm very satisfied with Conway. 

Pet dander requires a HEPA filter, with or without the boost you get from static charging depending on your tolerance for that. VOC filters such as Austin sadly come at the expense of HEPA performance. If you don’t know that you have a VOC problem you don’t need one of those. I’d avoid Honeywell just because their filter design is currently … expensive and power hungry. You just want to move as much air as possible and have a removable washable or disposable pre-filter. Look for units with high CADR, a carbon grid for pet odors, and washable or disposable pre-filters. Coway Airmega 250 and up, Winix, or there are some excellent new entries like the Airkit. Levoit Everest Air is good, but avoid their Core (round) series.

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're overlooking a couple key points: 1. Everything Shark builds is disposable. 2. There's no such thing as a filter that lasts 5 years. Even Austin and IQAir, I'm skeptical of their claims. My IQAir filter, at 2.5 years, is pretty discolored. And that's with ANOTHER HEPA FILTER in front of it to keep it clean. There is ABSOLUTELY NO WAY that Shark has a 5 year filter. I always worry when people make purchase decisions for air purifiers based on "style", because although I do like the look of my AirMega 250 for the master bedroom, it isn't "stylish" and frankly any purifier that looks nice probably doesn't clean air.

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 250 in the master bedroom. Winix 5500-2 in the guest bedroom. The kids chose their own, and two of them chose Blueair 411's. The other is using an old 3m Filtrete HEPA model because he likes the sound. But all of them have 12x12 rooms, give or take.

Sigh. If you searched this subreddit at all you’d see that in general round purifiers are suspect when they claim to be HEPA because HEPA filters cannot be deformed or vacuumed. But you’d also know that Levoit purifiers clean air quite well. If you REALLY need HEPA - and remember, asbestos is a fairly large fiber, compared to pollen - then just get a square filter from literally any manufacturer. If I were filtering possible asbestos, I’d be more concerned about the SEAL than the filter. Coway 150, Coway 250 and up have foam gaskets around the filters for a better seal.

Sigh. Listen, offhand all I know of is the Coway AirMega series 250/300/400. But seriously, please see other responses - you need to remediate the Asbestos.

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.

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

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

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

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.

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.

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
