"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."
"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."

"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 $$$."

"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."

"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."
Coway Airmega 150 or Airmega Aim. I have both and happy with both of them.
r/gurgaon • New to Gurgaon and planning to stay for 1-2 years max, what air purifier should I get? ->It does purify but I prefer mega for its ability to blend with the interiors and cheaper replacement filters
r/gurgaon • New to Gurgaon and planning to stay for 1-2 years max, what air purifier should I get? ->LEVOIT Core Mini Air Purifier for smaller rooms Large room either Philips Smart Air Purifier with real time AQI display or Coway Airmega AIM
r/mumbai • Air quality in Mumbai! Is it necessary to buy air purifier? ->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 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! ->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! ->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? ->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).
