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? ->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! ->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 ->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.

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? ->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 ->FYI, the C610 doesn't have the issue where you have to open the app monthly to get the HA integration to work.
r/homeassistant • Best Air purifier in 2025? ->I've had my Winix for nearly a decade now and it's still working great. I love it and recommend it to everyone.
r/BuyItForLife • View on Reddit →Happy with my Winix. I look at the app every now and then and see that it ramps up after cooking, seems to be working well.
r/Costco • View on Reddit →Whole house or room? Room I like winex, legit, Dyson. Whole home not sure. Make sure it's a hepa. See what size particles it can remove. Most of mine do not have carbon filters. I thought the carbon would make a big difference for smell but so far it does not. FYI it decreases dust which is great! Less cleaning to.
r/homeowners • View on Reddit →That Coway should not be over the Winix. The carbon filters in it are trash. Also, Dyson combo unit on the list? 🥲
r/AirQuality • View on Reddit →Nope hold Levoit accountable for their lies and don't buy their junk when there's other options. Get a Winix if you're on a budget. You can also get a box fan and put a filter on it but obviously it'll look like shit lol
r/AirPurifiers • View on Reddit →I have a few Levoit the same size as this one. I don't really care for them compared to the Winix and Blue Air ones I have.
r/AirPurifiers • View on Reddit →I love my Winix especially the feature that tells me when my dog farted before I even realize it (light turns red)
r/CleaningTips • View on Reddit →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 • View on Reddit →I have a Winix in my bedroom that's been running 24/7 since ~2010.
r/BuyItForLife • View on Reddit →We got the Winix ones and have been using cheap replacement filters from the web. No issues so far. We now have 3 as you could buy refurbs from them for like $50 a few years ago. Been running 24/7 for the most part.
r/Costco • View on Reddit →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 • View on Reddit →I have CoWay and Winix, Winix kicks on more frequently.
r/BuyItForLife • View on Reddit →I have 3 and I think they work well. One did get the annoying whining noise after a few weeks so I returned it and bought another, so far so good with the replacement.
r/Costco • View on Reddit →C610. The only thing is that's a "Costco" model I believe. I think Costco always sells things slightly different than what the manufacturer sells elsewhere (sometimes it means it just comes with an extra filter or one less feature etc) but I'm pretty sure you'll only find it at Costco with those model numbers!
r/moderatelygranolamoms • View on Reddit →It takes me two minutes to swap out filters in my Winix every few months.
r/homeowners • View on Reddit →We use Winix from Costco but turn off the plasma wave. They now have a child lock feature too which is nice. Honestly we rarely have dust in our house and it's such a noticeable difference when we travel or visit family so I truly think they work so well! They're around $100 but we have multiple throughout the house. We used to have a larger one but tbh it was much louder than the multiple small ones.
r/moderatelygranolamoms • View on Reddit →Seven years. The oscillating feature manes noise now.
r/homeowners • View on Reddit →This one was $100 on sale and is supposedly rated for more Sq ft than the 535. I also have a C909 which is bigger and uses the same filters as yours but I personally prefer the 610.
r/Costco • View on Reddit →Alen is the correct answer. It's overbuilt and comes with a lifetime warranty if you buy filters from Alen or authorized retailer. I'm a fan of Coway and Winix too. But Alen is clearly better built.
r/BuyItForLife • View on Reddit →Get a winix. Costco carries them and it's on sale right now. Comes with a 2 year supply of HEPA filter. You can keep the ionizing feature off if you wish to do so.
r/AirPurifiers • View on Reddit →There's only one correct answer. Winix Air Purifiers bought on sale at Costco. They're excellent & under $200. Buy generic replacement filters on Amazon.
r/homeowners • View on Reddit →I would get a Winix instead. I have several of these around the house along with Winix air purifiers, and these are not that great compared to Winix.
r/AirPurifiers • View on Reddit →Coway Winix or Alen. Remember to get the right size for your room by dividing the advertised sqft by (ideally) 4. Many manufacturers over inflate their sqftage. Edit: lmao at the downvotes. Classic Reddit. Most manufacturers advertise their 1ach (air changes per hour) metric. If you want to actually filter your air you need closer to 4ach.
r/AirQuality • View on Reddit →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 • View on Reddit →We've loved our various models of Winix found at Costco for bunny cage and litterbox.
r/AirPurifiers • View on Reddit →Winix c610 at costco for $99 Which includes extra filter. So you are good for 2 years
r/AirPurifiers • View on Reddit →I have both and like this one better. The C909 is louder on low-high but about the same on turbo. You also can't turn the indicator lights off on the C909.
r/Costco • View on Reddit →Winix from Costco/Amazon for about $130 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.
r/AirPurifiers • View on Reddit →Ask r/airpurifiers IMO the Coway is the only one worth considering on this list - blueair and Levoit are junk to be honest. Add Alen and Winix to your list. Also, 2 things to keep in mind with air purifiers. 1) the advertised sqftage of the machine is usually grossly overestimated. Typically these estimates are based on cleaning all the air in a room **once per hour**. If you're serious about purifier air. You need **four** air changes per hour. 2) Curb your expectations about it handling hair. Sure it may be able to catch come hair in the general vicinity of the machine. But hair is too heavy to suck in from across the room. To deal with hair and visible dust look at a **corded and bagged** vacuum. Which will also help tremendously with allergies.
r/homeowners • View on Reddit →I like my WINIX for these larger particles. It has a cleanable pre filter, charcoal filter and the hepa. I vacuum the pre filter weekly to get the cat fur off. I also use an old germ guardian that was my best buddy in a musty old office I worked. It's still a great unit just louder like a fan so I use it in the bedroom as white noise now It's worth mentioning a reminder to change the home furnace filter if you have one. I tend to change mine every 1-3 months during high allergen or fire seasons.
r/AirQuality • View on Reddit →I also have a Winix, not sure of the model number. It seems pretty good, I've had no problems with it other than it has gotten noisier over time, especially on the "sleep" mode.
r/goldenretrievers • View on Reddit →Winix C610. Bought in Canada Costco, but here's the [US link](https://www.costco.com/winix-c610-4-stage-true-hepa-air-purifier-with-wi-fi-and-additional-filter.product.4000295784.html?COSTID=iosapp_deeplink_25.4.5&TRACKING=NO&sh=true&nf=true) for it.
r/Costco • View on Reddit →I like my cheap filtrete for white noise in the bedroom, I have two winix filters in my office and living room. Both have huge filters and prefilters that are cheap to replace. I used consumer reports to pick them out. Honeywell uses small filters and I wouldn't recommend them unless it's a very small room.
r/BuyItForLife • View on Reddit →I prefer winix , filters are good and cheap to replace ,
r/AirPurifiers • View on Reddit →Yup we have several, one in our living room, one downstairs, and one in our bedroom. The Winix brand is good and sometimes Costco has them on sale. In our bedroom we have a smaller Levoit. It helps keep the air fresh, helps manage cat hair and dust, and of course is nice when it's smoky out 🥲
r/TwinCities • View on Reddit →Winix is one of the better ones. When it comes to buying air purifiers, look for the companies that have been around for a long time to ensure replacement filters won't suddenly become unavailable or unaffordable.
r/Costco • View on Reddit →ya maybe, winix does the same...pre filter, carbon filter, hepa filter....I still had to change the carbon and hepa every six months.
