"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."

"how quiet it is. ... it's remained silent at night after a couple of years."
"it runs 24/7 for more than 5 years and works great and silently."
"That said my IQ Air at level 2 is damn near silent. ... At its lowest setting (level 1), it achieves complete silence, making it ideal for bedroom use. ... When operated at level 2, while the sound becomes noticeable from the bed, it produces a different type of noise than the Levoit models - specifically, it lacks the characteristic "wooshing" sound that Levoit units tend to make. Sleeping with the unit at level 2 is still comfortable."

"never deflates"
"Also pitched it on bare rock using rocks to hold the stakes on a decently breezy night and it was pretty bombproof."

"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."

"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"

"Also I just put it in the bathroom w my bf while he poops. No change in the air reading or smell of the bathroom."
"Just stay away from the Honeywell HPA models. They all develop a burning smell. I've swapped my 2 out a total of 6 times."
"They’ve massively oversold how large of a space this device is suited for. ... I found it did nothing for odors. ... There is basically no carbon filter in this so it won’t filter odors at all… ... Correct. I wish I had realized that before I bought it but oh well. The carbon sheet is advertised to make one think it will help with odors. Live and learn"

"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."

"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."
"If you decide to get the Winix 5500-2, keep the plasma wave OFF. ... It's Winix version of ionization which is of concern for people who care about ozone. ... Supposedly it's negligible but i don't take my chances so I keep it off."

"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.."
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? ->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? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
