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

"We bought a relatively cheap one off Amazon for £100, make is Lefant, had it about 6 months now. Honestly it is brilliant"
"There’s 3 filters. A large particle one I vacuum monthly. A medium particle filter that replaced every 3 months and a fine particle filter that’s done every 12. A years kit of them is $30 on Amazon"
"Filters are cheap too."

"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 are also great to have during annual west coast wild fire smoke season and keep particulates in the house undetectable even when it has been horrid outside."

"We've loved our various models of Winix found at Costco for bunny cage and litterbox."
"I love my Winix especially the feature that tells me when my dog farted before I even realize it (light turns red)"
"completely neutralized the smell of a bunny cage for almost a week (between changes). Bunny and cat pee are similar, so I bet it would work."

"My two Winix units are 11 years old with 24/7 use and still going strong!"

"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."

"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."
"The pre-filter is insufficient and the HEPA filter gets dirtier much faster."

"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."

"PlasmaWave is just a glorified ionizer. I personally cannot stand the scent of ionizers, it gives me headaches. ... Anything with an ionizer gives me headaches because of the ozone they produce."
"Both of my Winix air purifiers started smelling like smoke"
"At that point, why bother paying for that feature? Just buy a purifier without the added tech and save a couple of bucks. Honestly, the simpler the better. Too much tech can lead to added points of failure."

"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."
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? ->I second the Winix brand. I've had the 9500 for SEVEN YEARS and it's never let me down, still going strong.
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->Any filter with a charcoal filter layer will help some (Winix is one brand commonly available at Costco…I also have a more elaborate Rowenta)…my Winix came with multiple charcoal layer replacements. Dealing with total incontinence here, and not to criticize your MILs efforts, but you might want to look into the actual sources of the odors. Chairs, clothes that sit around waiting for wash, previously soaked furniture or carpet? If bedding or fabric furniture smells and you can replace it, do so. I use a combo of Depends on my father, and all his sleeping or seating surfaces have a first layer of puppy pee pads (Costco has large ones that work well and are cheap), and then a fabric layer on top (whether sheets or a chair cover or towel, tucked into the sides of the chair). Once he’s wet, after I changes his pants all clothes and chair covers and bedding goes in the wash (3-5 loads a day). For the mattress you can find on Amazon washable mattress covers (the whole bed ones don’t work that well but that’s my base layer and then a thicker more absorbent one that I fit across the middle section of his bed, and on top of that layered dog pee pads). So again, not sure if any of this advice helps but this method works for me.
r/CaregiverSupport • Air purifier for urine smell ->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.
