"Replacement filters are like $12-15 each and I can usually go 12 months before needing to change."
"Not only are official filters likely to be available, there are tons of aftermarket options available as well. ... If filter availability is a primary concern, the AP-1512HH or 200m are tops."
"Big plus is that I can buy filters on Amazon for cheap."

"360sqft is on highest mode 24/7. The noise can become unbearable and people will switch to lower modes, thus being ineffective."
"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."
"You need one per room, they dont really cover more than a few hundred sq ft."

"It does get loud on basically all but the lowest setting. ... Anything higher than that and I turn up the volume on the TV, can’t hear conversations in other rooms, etc."
"One rattles like crazy. It's only a couple months old."

"They’ve massively oversold how large of a space this device is suited for. ... I found it did nothing for odors. ... There is basically no carbon filter in this so it won’t filter odors at all… ... Correct. I wish I had realized that before I bought it but oh well. The carbon sheet is advertised to make one think it will help with odors. Live and learn"
"Idk, I don’t find the Airmega 1512hh helpful when it comes to smells. ... The carbon sheet feels useless in comparison to pelleted carbon."
"There is basically no carbon filter in this so it won’t filter odors at all…"

"the filter costs have you replacing filters every 3 or 4 months with full use."
"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."
"Filters are $$$."

"The problem with Coway is poor customer service. ... They tell me to return it to Amazon, but I don't have the original package. So I'm supposed to purchase a new box from them to return to Amazon. Amazon won't accept it anyway because it's outside the 30 day return window. Coway's solution is to stop responding to emails."
My recommendation (had three in an apartment for eight years, they didn’t miss a beat) is the Coway Airmega AP-1512HH Mighty. Not cheap (~$200) but wait for a sale/coupon if you can. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/
r/AirPurifiers • Recommended purifiers for wildfire smoke? ->You’re going to want a Coway. https://www.nytimes.com/wirecutter/reviews/best-air-purifier/
r/AirPurifiers • Good AirPurifiers on Amazon to help cat/ferret smell? ->I bought two air purifiers just last week after reading this sub! Coway 150 and ap-1512HH(W), they were on sale on Amazon.ca and I read somewhere I can use the carbon pellet filter from the AP-1512HHS in the non S version. So far so good!
r/AirPurifiers • ❗NEW 2025 USA Air Purifier Buying Guide (now in the subreddit's wiki)❗ ->I have a Coway Airmega AP-1512HH Mighty that I brought to all my classrooms last year! There is definitely evidence that an air purifier can reduce illness in classrooms. And I tell my students not to come in if they’re sick! I think an air purifier is a great idea and an easy way to reduce illness. Hope everything goes well for you this year.
r/Professors • Virus prevention - air purifiers ->I have the coway airmega which is the wirecutter top pick (https://www.nytimes.com/wirecutter/reviews/best-air-purifier/) I liked it enough to buy a second one for my home. It has been great and it does make a difference.
r/goldenretrievers • Air Purifier? ->Agreed on coway! They have a pet filter for two of their units too, the AP-1512HH and the 200M. It specifically tackles pet odor, dander and ammonia stuff in the air from pet waste.
r/homeowners • Best Air Purifiers for Pets? ->I love the coway too! I have the Airmega Mighty AP-1512 HH and I've been using it with the intense smoke filter
r/LosAngeles • What air purifiers are you using that’s helping during fires? W. no ozone and BPAs? ->Was comparing the sales and planning on getting another Coway air purifier for my house cause I loved the previous two we got. Seems like you get a better deal on cowaymega.com. Dropping this here for anyone who needs!
r/AirPurifiers • Gonna get another Coway air purifier ->Wanted to clarify this is the Coway Airmega Mighty or Coway AP-1512HH Mighty air purifier, the same one Wirecutter has been pushing the last ten years or so, in case anyone was confused!
r/AirPurifiers • Gonna get another Coway air purifier ->I saw the Coway AP-3008FH in a client's office once, it looked HUGE so I would never consider getting it for my apartment. For 1000 square foot you could go for the Coway Mighty AP-1512HH. I have two units in my apt. Or if you want something that overcovers, you could check out the 350 or 450 for a big open space.
r/AirPurifiers • Question about Coway AP-3008FH ->Conway Airmega 200M (or AP-1512HH, basically the same with different look) has been one of the most recommended for years. Not only are official filters likely to be available, there are tons of aftermarket options available as well. I don't really have power failures where I am, but I just pulled the cord for 30 seconds, and when it came back on it was still in the previous mode from before I pulled it. All the other options fit your critera pretty well. My only complaint is the blue air quality light on the top panel is brigher than I want in my bedroom, but I just put some tape over it. You can get LIGHTDIMS or similar to do the job and look good doing it. Those are highly reommended in general...
r/BuyItForLife • Air purifier recommendations ->I don't know anything about that one. It uses a different filter set, but probably fine. If filter availability is a primary concern, the AP-1512HH or 200m are tops. If looks and performace are primary concerns, maybe check out rtings who is doing the best analytical testing at the moment and see if any of them float your boat. https://www.rtings.com/air-purifier/reviews/best/bedrooms
r/BuyItForLife • Air purifier recommendations ->I've had a coway AP-1512HH running for years now. Works really well except that the fan speed modes are super quiet, quiet and ultra loud. I also do not like the blue led but just cover it. Big plus is that I can buy filters on Amazon for cheap. It was listed as best recommended at some as far as I remember.
r/smarthome • What's your best pick of home air purifier that actually improves indoor air quality? ->This is my recommendation. We have a couple of these running on low all the time (we live on a busy street and they’re nice to have for our fire season).
r/moderatelygranolamoms • Are air purifiers worth buying for pets? Which options would be the best you've tried? ->We have the airmega that [looks like an iPod](https://a.co/d/8WCcJ0z) and love it. It goes on sale every once in a while, I think.
r/moderatelygranolamoms • Are air purifiers worth buying for pets? Which options would be the best you've tried? ->I tried a few of those models at home, and the Coway AP-1512HH has been the one I’ve stuck with.
r/smarthome • Best air purifier for home on the market today but not too pricey $400+? ->The Coway Mighty - we liked it so much we ended up with another one for our second floor.
