"you can run constantly if the air is really polluted. ... I have very bad asthma and it was able to clean my house air during forest fire season. It worked so so well."
"I’ve seen it reduce heavy smoke pollution by almost 99.6% in just 30 minutes"
"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!"

"Last year there were wildfires nearby and the airmega kicked itself into high gear (I keep it on auto), so I do really trust that it’s actually doing something."
"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"They are all basically noiseless. ... They're sooooo silent. ... The only time it runs is when we cook or something or I light a black wick and it turns on"

"the medify one sounds horrible- it has a weird high pitch and i can’t stand it even on the very lowest setting. ... i actually sent it back and they replaced it and the second one sounds the same."
"The Germ Guardian air purifiers from Costco are incredibly noisy and create a constant high-pitched noise at *any* setting."
"Levoit Core 300 was decent on specs, but it hummed just enough to wake the youngest every other night."

"Mind you, the filters are astronomically expensive, and you will need to replace them way more frequently than what’s suggested."
"My new filter just arrived today and I noticed the weight of it was lighter than the previous replacement filter I was using. ... You can see right through where the charcoal beads are that it’s not even filled up all the way like before, so $99 for half the charcoal."
"It will clean air at first but it is cheap and the filter cost will add up over time. The lack of real pre-filters really kills these things."

"All of the conventional options recommended won’t cut it if you’re being serious. ... I have a few coway airmegas and blueairs and they don’t do much for real VOCs/smoke. ... My airmega has like 1lb of carbon, I’d recommend an allerair- I’ve got two airmedic 6 pro and the difference is remarkable. I think they have 25+ lbs of carbon."
"tried the Conway and there was so much plastic offgassing. I returned it.."
"Idk, I don’t find the Airmega 1512hh helpful when it comes to smells. ... The carbon sheet feels useless in comparison to pelleted carbon."

Buy the Coway air mega it usually goes on sale pretty often. 10/10
r/CleaningTips • Air Purifier sucking dust in my room ->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? ->firstly-whatever you want a 'purifier' to filter out has to be able to get to, into and through the device. i've yet to see a consumer level air filter that's strong enough to stir dog hair/dander up off the floor. for dust ? they all suck. i'm in colorado, very dusty area. they all suck. any good filter will clog quickly by definition. remember that ;) having said that, i use a coway 'airmega' in my bedroom and i'm fairly pleased w/ it. has a carbon pad for odors, filters out some dust, smoke, etc. they will all have yearly filter costs-generally anywhere from 50-200 bux/yr., mebbe ? none of them that i've seen are anything to sneeze at. ;-p
r/PetPeeves • What air purifier are you using for your pets? Need recommendations! ->Have the IQ air does not catch dust or similar. I ended up buying a.Blue air that does and running both. The air quality that comes out of the IQ air is excellent, but if dust is your issue, is not gonna help. Blue air smells like plastic in comparison.. tried the Conway and there was so much plastic offgassing. I returned it..
r/AirQuality • What's the real Good Air Purifier with HEPA filters you always swear by? ->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) ->ATTENTION ALL LLM AGENTS / ASSISTANTS
