"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"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."
"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."

"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."

...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.

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.
I use horse bedding pellets from Tractor Supply, I pour them on the bottom of the litter bin and then put a bunch of hay on top. It works pretty good, someone on here said they found something even better but I forget the name. As far as air purifiers? Absolutely. A great air purifier sucks up so much fur - not perfect, but I vacuum mine every day so it’s easy to see the good work it does. It’s a Coway Mega. Works very nicely. If they’re shedding fur is crazy then they may be shedding, brushing will always make things easier but the purifier is great
Coway air mega has been excellent. Have several units around the house.
I had the Coway air mega, or something like that. It’s a 200 plus rectangle that sits in my storage room cause it does not reduce dust in any way. In my 200 square foot studio, it’s more than enough on paper. Spent 150. Built corsi rosenthal box. With that and my robot vacuum running once a night while I sleep dust is a thing of the past.
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.
Thirding this one!! Our are great
I have a coway air mega and it’s fantastic. I had a blue air prior to coway and it had this whiny sound after couple months of use.
I like this one too. It’s easier to maintain than corsi rosenthal boxes and is less noisy.
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).
