“While not the most expensive on the market, the annual filter cost is a real expense to factor into your budget.”
“Um-- it's no joke. At first, I was a little disappointed that it wasn't kicking on automatically while I was cooking since reviewers mentioned that a lot but then I realized I wasn't really cooking the types of foods that produce strong odors. It DOES seem to ramp up into it's higher filtering modes (from the eco mode) whenever my bird starts to preen, thus”
“And it doesn't seem to be helping at all with pet odor/litterbox odor.”
“Build quality is solid for a $160 purifier. The plastic housing does not feel premium, but it is well-assembled.”
“I just bought [this one](https://cowaymega.com/products/coway-airmega-200m) and it gets very mad at me when I dab, but the couple upstairs hasn't complained of smells.”
“While the perforated holes on the Airmega 300 are quite premium, the gray front plate of the Airmega 200M makes it cheap and unreliable.”
“When set to high, it emits a noise that measures up to 59.5 decibels, which we found to be distracting and somewhat annoying.”
“It works wonders. Cleared out the funk my renters left downstairs in less than 24 hours (old house, very little air vent).”
“recently bought 2 large air purifiers for our 1,400 Sq ft house. It's helped quite a bit.”
“It is indeed the AP-1512 which is fantastic”
“Im happy with this, although I paid $119 when I bought it. Nearly silent on the regular setting, and it gets more powerful when it detects a problem. I know it works because whenever I cook it starts blasting.”
“We use this for dog smell, works great. Has 3 filter layers including charcoal for odors:”
“I have one at each work bench at my work (5 stations total), they completely filter out any bad flux smells. Adjacent offices stopped complaining when we installed these. They were put in for COVID, so each employee had a fresh air supply, but had the added benefit of working well for fumes. The auto setting works well, it kicks in within seconds of solde”
“I just got an air purifier and it works great. Coway Airmega 200M. It’s about $200 and so far is doing a great job with dust and animal hair as my son has allergies”
“I don't \*know\* that it works well, but I'm pretty happy with - the doggy smell (I have two very large loves) seems minimal now.”
“I've had one for five years and it's still working like the day I've got it. In contrast, my Winix units (I've bought three, two from Costco, one from Amazon, all gone now) started making really annoying noise 14-18 months into ownership.”
“the Coway Airmega 200M. It’s worth the money. It’s the same as the 150…just doesn’t look like massive iPod shuffle.”
“I’ve been happy with [this HEPA filter](https://www.walmart.com/ip/Coway-Airmega-200M-Air-Purifier-with-True-HEPA-and-Smart-Mode/838527609?selected=true). It’s quiet and you can turn off the bright blue led if you want, so it’s nice for the bedroom.”
“There's a filter that needs replacing every so often, but in between replacements you just vacuum it. And yes, it gets full of dust and hair. My cat's litter box is like three feet from my desk and I don't think I'd be able to work in that room without it”
“Absolutely love our Coway Airmega 200M. In fact, will be buying more shortly.”
“1x Coway Airmega 200M piatto che mi copre 40mq a piano terra.”
“We use two of these in our home, we have trouble sleeping without one running in our bedroom at full blast. Would rebuy instantly if it broke.”
“The activated carbon filter effectively reduced common household odors from cooking and pets within one hour.”
