"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 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."
"Yup, I turn it on after cooking and odours disappesr"
"The dog smell is already gone after a couple hours"

"I had a Levoit Core 300 that developed a fan whine after a year. ... Went through the RMA process and they sent me a new one, which developed the same noise within a few months."
"We have 2 levoits and even on 1 I can hear it across the room with the TV on. ... They both have an ear-piercing high pitched sound that I can't stand."
"Levoit Core 300 was decent on specs, but it hummed just enough to wake the youngest every other night."

"Mind you, the filters are astronomically expensive, and you will need to replace them way more frequently than what’s suggested."
"My new filter just arrived today and I noticed the weight of it was lighter than the previous replacement filter I was using. ... You can see right through where the charcoal beads are that it’s not even filled up all the way like before, so $99 for half the charcoal."
"It will clean air at first but it is cheap and the filter cost will add up over time. The lack of real pre-filters really kills these things."

"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."
"I would run the Winix with the ionizer off, idk if the slight increase in ozone exposure would be harmful."

"I think that having a pre-filter like that is the main problem because you have all these particles stuck to it which can become attached to anything or anyone that touches it ( for example pet's fur) and then they carry those contaminants everywhere again. ... I'm in Los Angeles so I got it because of the wildfires and possible asbestos but I'll be returning it because of this design. ... Yes now imagine it sucking all the bad particles from nearby wildfires, for example asbestos. Then a dog can brush their body through the fabric and carry it around until it gets lose in the air again ... I didn't even know the old design was the same way. How can they be rated so high in many websites? Even consumer reports has the of them. Now I even distrust CR"
"it was so poor at performance. ... With the Blueair, every month i have to clean the pre filters as they are caked in dust! I had the winx for a while and no once did the pre filters get any dust on them, despite it being left on 24/7. You could visibly see dust building up on its base, and around it but nothing inside it. ... but it wasnt strong enough to make it inside to the pre filters."
"It's no wonder the filters last for 5 years, the thing never runs. ... They are not "purifying the air" if they are not moving the air through the filters."

"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."
"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 ->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.
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
