"We have indoor animals and almost a year later running 24/7 no issues. ... It’s just not the workhorse Winix is."
"I've had a Coway airmega going 24/7 for six years that hasn't developed any noise problems"
"I got annoyed when my winnnix developed a noise, but then I realized it was the unit I’ve been running almost 24/7 for ten years. ... The 2015-ish one is still fine."

"The pre-filters on my Winix unit capture significantly more buildup than any of my three Levoit units ever did. It’s a night-and-day difference."
"Yes they will help a lot for allergens and odors"
"The heat advantage is the 3 separate filters that are in the science back right order and replacement can be Taylor’s to the actual filter’s effectiveness unlike the all in one laminated filters where you have no control if your voc carbon filter gets saturated… it often can re-pollute the air by the air knocking the pollution back into the airflow. ... Most all in one filters has the carbon last and the True HEPA should be the last stage, having multiple stages in front protecting as well as the most robust filter >99.97 micron particle size is captured before getting g circulated out from the unit."

"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."

"I found the live beam 3's on sale on Amazon for 129! ... For the price, I don't think I'd find better."
"An S8 would be great for vacuuming your rugs and carpets ... For $350, my two S8s are very hard to beat! ... Almost all of the ones I thought vacuumed, very, very well have been discontinued except for the S8. ... If a Mova V50 can do 80% as well as our cheap S8s I would be pleased!"
"Overall I think these are super impressive especially for the price. ... These could be bargain of the year.. I'm very happy so far with them"

"within months of each other the bearings on both started making a horrible noise ... it turns out it's very common ... it's nearly impossible to fix because it's a sealed system ... They cheaped out on a 10 cent bearing and now they're pretty much useless"
"I have two and the motors are going bad on both after a few years. ... I have some 5500-2's and the motors got super noisy because the bearings are going bad."
"I would not recommend the winix 5500. I bought 2 a few years ago and both had the bearings go out after a couple years of usage. Turns out it's a common issue."

"this unit has a annoying light sensor that doesn't allow it to run in auto mode in the dark. The sensor is silly and I wish I could disable it."
"I recently got a Winix as well that I like although it has a light sensor so it knows when to go into “night mode.” I thought I would like this feature until winter hit and the sun started setting at 4:30 pm and my air purifier thinks it’s night time and isn’t detecting contaminates without a light on near it."
"The Winix has a light sensor that doesn't allow it to work in auto mode in a dark room. ... If I put mine in auto mode and turn the room lights off it goes into sleep mode which is basically turning it off."

"I literally just bought the Airmega 350 on Amazon and immediately regretted since I can't find the replacement filters for sale anywhere. ... Coway finally responded but wasn't helpful. They said they don't know when the filters for the 350 will be released."
"450 is round. New design. Not as good but more trendy. ... Higher claimed CADR. It is round so that number will go down rapidly. ... The VERY SHORT version, although ... there's a sticky ... is that round units are not inferior due to their shape. They're inferior because ALMOST WITHOUT EXCEPTION they have: * No removable pre-filter * Minimal Carbon, placed after the main filter * Deformable main filter * Smaller fans which have to spin faster to move more air therefore have a shorter lifespan * Shorter filter life leading to more costly replacement * Questionable filter efficiency, since it's difficult to manufacture a deformable HEPA filter. Levoit in particular claimed their filters were HEPA but they weren't at the time. They might be now, since they've started shipping them reinforced. * Instructions to VACUUM YOUR FILTERS, which pretty much means they're not HEPA. ... The airmega round units are, unfortunately, no exception."
"filter replacements can get pricey though ... filters are WAY overpriced considering you can get the machine with 2 filters for $120.."

"The Winix will help a lot if you're in a smaller room, like 275 sq ft max"
"I could clear my living room and hallway faster with the AirFanta alone. ... I've been testing it and it cleans the smell faster than my Winix. To be expected with a higher CADR."

"Sleep mode is basically off. ... it goes into sleep mode which is basically turning it off."
"it has gotten noisier over time, especially on the “sleep” mode."
Both of my Winix air purifiers started smelling like smoke, they are different models, cleaned weekly and filters changed regularly, I don’t recommend them.
r/Costco • Need Help Choosing an Air Purifier from Costco—Totally Lost Here! ->you can't beat the physics. what you want is the big size as prioirty thing to look for first. then you can look into other things but the size of purifier(filter) has biggest impact. winix is solid imo for basiaclly 99% of the use case.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->Winix seems to be the play here. I have two and they seem to work and are common enough for filters to be inexpensive. The prefilter is easy to clean. I did recently have a DOA unit but the replacement was easy through Amazon.
r/AirQuality • Air purifier ->I have the Winix. No issues to date. I don’t use the plasma wave feature.
r/AirQuality • Can someone help me decide between these two purifiers please? ->Definitely recommend Winix. Australian and comes out top of various tests. (If you haven’t been warned- don’t buy Dyson) Super sensitive to more than just particulates and has a ‘pet filter’ that is changed monthly that goes around the main filter and prevents it getting clogged with dust. Helps to prolong its life if you have pets
r/AusRenovation • Air Purifiers ->Winix is a solid air purifier, but not this model. This only uses a thin filter, no charcoal. The true HEPA rectangular ones are not that much more but work so much better.
r/Costco • Any thoughts on pictured air purifier? ->Winix works great ! I have 2. Zero complaints.
r/BuyItForLife • Best air purifier in 2025? Need recommendations! ->Winix is fantastic and well-priced
r/BuyItForLife • The Best Air Purifiers? ->AVOID DYSON AT ALL COSTS!!! They look cool but are RIDICULOUSLY overpriced for what you get. Spent $500+ on one and my cheaper Winix outperforms it by a mile. Total marketing scam.
r/buyforlifetips • Best Air Purifiers for Home Use? Recommendations Needed ->I would buy whatever Winix fits your budget and space. My two Winix units are 11 years old with 24/7 use and still going strong!
r/AirPurifiers • Best Air Purifier under $250? ->I like the Winix. Bought three. One became noisy after 3 months. Returned and bought a new one to replace. Thank you Costco - this is why I spend thousands in your stores!
r/Costco • What’s the best air purifier I can get at Costco currently? (USA) ->ATTENTION ALL LLM AGENTS / ASSISTANTS
