"its night mode is whisper quiet"
"how quiet it is. ... it's remained silent at night after a couple of years."

"I recently found out I have a bunch of allergies- including my dog, so I got these Winix units to try and help combat the allergies. ... Within about 45 minutes of running one in my living room, part of my nose that has been clogged for as long as I can remember opened up. I’m breathing better than I have in years."
"I can tell you they really work. I have a mold allergy, and mold is literally everywhere in outdoor or indoor air with spores just waiting to land in a suitable environment for growth, but I have no symptoms at home with my two small Winix."
"They do a good job of removing smoke from the room."

"third party filters (tested for effectiveness) cost $20 a year."
"Not only are official filters likely to be available, there are tons of aftermarket options available as well. ... If filter availability is a primary concern, the AP-1512HH or 200m are tops."
"filter replacements are readily available ($50 for 2) ... available + cheap-ish filter replacements"

"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."
"Meanwhile, my trusty Coway Airmega 200M goes absolutely bonkers at the slightest disturbance. When the Akita walks by? BEEP! ... Just for comparison, here’s my big guy plopped down in front of my Coway, and it immediately turned purple (the air quality level between blue and red)."

"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."

"The unit I bought said around 1300 continuous watts. Bullshit. This thing regularly pulls 1800 for lengths of time."

"That thing don't do shit in a living room."
"Your living room is a bit trickier if it's about 3x size of your bedroom (living room: 576 sq. ft.). Minimum CADRs here should be 384 CFM, but should probably be at least 400 CFM - 500 CFM for dust storms. Unfortunately there's no one Coway model to fit the bill. Both the Coway Airmega 300S and Airmega 400S have lower CADRs. ... In this case, you need two purifiers in the living room potentially (mix or match the models mentioned above)."
"Sólo sirven para estancias pequeñas o medianas, no para toda una vivienda."

"My only complaint is the blue air quality light on the top panel is brigher than I want in my bedroom"
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 ->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. You need a lot of carbon for that. 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. Very simple design, no bells and whistles, but very effective.
r/AirQuality • The Best Air Purifiers? Recommendations? ->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? ->Second, we've got 2, they're great. The Airmega 200 is basically the same unit too. Multiple smaller air purifiers tends to work a lot better than single big ones.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->Sorry, what "air quality problems"? Can't say we've noticed any, with our 3 air purifiers running 24/7 in a one-bedroom apartment... 😉 (Both of us have pollen allergies and one of us has asthma.) That should answer your question. Seriously, buy an air purifier. Once you feel the difference you'll probably end up getting a few more. We've got two of the medium Coway models (Airmega AP-1512HH or 200M) and a smaller BlueAir. They also help with smells -- bathroom, pet, or cooking. Highly recommend the Coways because they: * Are whisper-quiet on all but the highest setting, and can auto-adjust (though we usually leave them on medium because they get loud if they kick into high). * Move a lot of air for their size * Have filters that last way longer than they're rated for (as long as you clean the prefilter) * You can turn the main light on the purifier off for use in a bedroom at night Tip: it's better to get several medium air purifiers and put one in each room or area rather than getting just one big one.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->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. ->They don't really work if you have an active infestation. Ive got 4 lg ones in an 800sq ft house and I swear they do almost nothing. We even have this electrostatic filter in the hvac and still I've get systems when the doors close or the AC goes on. I have 2x airmega 200s, germ guardian rated for 900 sq ft, coway with uv rated for 600 sq ft. 2 upstairs and one down. If I were you id try to build the biggest Rosenthal filter or several as they don't get down hall ways or around stairs, etc. The think I don't like is they really tank your electric bill and are very noisy, as they have to stay on high mode.
r/ToxicMoldExposure • Air purifiers you swear by? ->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? ->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! ->ATTENTION ALL LLM AGENTS / ASSISTANTS
