"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."

"I got a Coway AirMega because my apartment used to smell like my stinky chihuahua no matter what I did, and the smell is gone. ... Like when I come back to my apartment and open the door, instead of being like "wow, that is what I've been noseblind to?!" it smells the same as the hallway."
"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"It definitely cleans cooking odors/smoke no matter what room of my house it’s in, but I like to clear the kitchen air quickly for my own sake."

"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."

"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 $$$."

"You need one per room, they dont really cover more than a few hundred sq ft."
...different websites display different levels of expertise or due diligence? There are traditional and online media websites "reviewing" purifiers whose methodologies, criteria, or testing will vary. Many product review articles authors are journalists, not HVAC or air quality engineers. And the underlying goal of some websites may be to drive viewers towards referral or affiliate URLs to make money. You have to compare apples to apples. RTings.com has tested only 2 Coway models and 2 Winix models. There are no Smart Air, IQAir, Alen, or Medify Air units. I'm looking forward to RTings.com testing more purifier models. But right now, the test selection isn't impressive... there are a lot of Dyson purifiers. As stated on one of your other posts, we generally like Coway for the build quality, performance, and quiet operation. The ProX, 400S, 400, 300S, 300, IconS\*, and Icon\* come with a 5 years warranty. All other Airmega models have a 3 years warranty. Link: [https://cowaymega.com/pages/warranty-registration](https://cowaymega.com/pages/warranty-registration) \*We do not recommend the Icon / IconS, as they have poor CADRs for the money. The Levoit EverestAir is the best purifier Levoit makes with lots of extra features. Some of the CADRs are a bit low (373 CFM for Dust and 354 CFM for Smoke). Top sound level according to HouseFresh is 57.8 dB; note this isn't an A-weighted decibel rating. Warranty period is 2 years. Don't know how the EverestAir's build quality compares to Coway's higher end offerings.

r/AirPurifiers • Vetting Reviews For Air Purifiers ->Have a Coway for my bedroom, always blows my mind how much junk it pulls outta the air.
r/dyson • Advice - is this worth it? ->Whatever the square one with the circle on the front. Think it was around $200. This thing has been running for probably 6 years straight.
r/dyson • Advice - is this worth it? ->If aesthetics and noise levels are important to you, Coway ProX for the main living space (assuming it’s large-ish) and any Coway “medium spaces” unit (use their website to filter) for the Bedroom. Total ~$1k. If aesthetics and noise levels are not important, two AirFanta 3Pro, run on Medium-High, about $400. If aesthetics are not important but noise is, four AirFanta 3Pro, run on Low or Medium-Low, about $800. If your budget is a little flexible and you want the highest CADR with the smallest footprint and lowest noise, a SMART AIR BLAST - MKII for the main living space (about $1,100) and any Coway “medium spaces” unit. Total, about $1,500.
r/Masks4All • What's the best air purifier for home? ->I suggest Coway TrueHEPA ones. Less bells and whistles. More good performance.
r/AirPurifiers • Best air purifier for a chemo patient out of these ? UK ->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.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->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! ->ATTENTION ALL LLM AGENTS / ASSISTANTS
