"We have indoor animals and almost a year later running 24/7 no issues. ... It’s just not the workhorse Winix is."
"Yes, I also have 2 of these running 24/7 for 5+ years."
"I own the 5300-2 and 5500-2, about 7 units total. No noise on any of them running continuously. ... all of my 5500/5300's are over 6 years old."

"much better bang for the buck"
"They are the best bang for your buck when considering airflow, energy usage, and filter replacement costs. ... You can find them on sale for around $150."
"buying several 5500-2s is more effective and efficient than a single large unit when factoring in things like purchase price, energy use, filter replacement cost, and effectiveness at filtering particulates."

"you can run constantly if the air is really polluted. ... I have very bad asthma and it was able to clean my house air during forest fire season. It worked so so well."
"We've loved our various models of Winix found at Costco for bunny cage and litterbox."
"If you want the most sensitive one, Winix 5500-2. ... I had daikin and this one side by side and winix reacted to cooking smell, open window etc where as Daikin only reacted in extreme cases."

"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."

"Love how quiet it is ... almost a year later running 24/7 no issues"
"Settings 2 and 3 move a significant amount of air and it makes the perfect level of white noise for sleeping."
"I love mine because it's not as noisy as the cheaper brands ... I run it on it's highest setting when I'm not in the room, and it's second highest setting when I am close to it."

"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 had it for about 3 days at that point and didn’t realize I couldn’t turn night mode off until last night 😂 ... I just pushed the 8hr timer so it stayed on during the night, but we go to sleep pretty early so it turned of while we were still sleeping and if I remember correctly (because I was half asleep) it played a loud jingle when it went off which I thought was strange."
"Yeah I covered mine with black tape."

"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."
"The Plasma feature is concerning. ... Understood. I have those same concerns. I just turn it off."

"I don't recommend Winix 5500/5300 for the simple fact that it doesn't turn back on automatically when there's a power interruption."
"Nope, to get around this I leave it on 24/7."
"They will not turn back on automatically after a power outage."

"Winix 5500-2 and 5510 do remove some VOC, other models don’t. And “some” is relative. I wouldn’t trust them with a major chemical incursion but they ought to take odors out of the air."
"I had two winix 5500-2 purifiers but they weren't doing the job especially for Voc's."
"The carbon filters in it are trash."

r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->It doesn't pull air like the 5502 and 5300 and this is the next generation of the 5500-2. On speed 2 the purifier does not hold toilet paper (one squate) the 5502 does. And it doesn't blow air out hard as the 5502. I guess it is my test but I'm not keeping it. I just ordered another 5502.
r/AirPurifiers • Thoughts on winix 5510? ->I ended up using the AHAM to help me decide thank you! Turns out coways not verified by them. And I started to see some discrepancies about their micron particle size being marketed something different than the true size… so I went with the winix 5500-2. Seems good so far! Thank you for the recommendation on AHAM
r/AirPurifiers • Narrowing down my Air Purifier choices ->I ended up purchasing the winix 5500-2 after looking up the AHAM (someone mentioned on my post to check there and it helped me get a good idea of realistic square footage and CADR because they verified them) and it seemed to be the best choice for what I needed in my master. Figured I’d start there since it’s such good value and if I didn’t love it I can get another brand for downstairs, but so far I like it! Not too much noise and I think I feel a difference already! I also deep cleaned right before I installed it so that might have helped too 😅 We have a dog too so fur accumulates quick and it’s hard to keep up with my 18month old baby. Noticed a big difference that my eyes are not as itchy! Do you keep yours running through the night? Mine seems to turn off, but I think I can disable “night mode”. We’re sleeping in there all night and I’m thinking I’ll see even better results if I keep it going.
r/AirPurifiers • Narrowing down my Air Purifier choices ->I have seen that too. That they released a statement that there’s no purpose to its green filter other than marketing? I ended up with the winix 5500-2 for my bedroom… still kind of like the idea of the coway for my downstairs, but I did see what people were mentioning about the green filter.
r/AirPurifiers • Narrowing down my Air Purifier choices ->I have the older Winix and run it 24 7 365 without problems. I just need to replace the filter once a year. I have not tried this round model. Edited to add. Mine is a 5500. I forget the Costco model number for the equivalent but it was the same unit that Costco was selling for 2018-2021. Been running non stop since 2018 and no weird noises from the blower fan which is amazing.
r/Costco • Any thoughts on pictured air purifier? ->I vacuum the mesh pre-filter and charcoal pre-filter every week, and i use the orange filter from Winix. I can get more than a year out of them. The orange filter does start to look a bit black at that point.
r/Costco • Any thoughts on pictured air purifier? ->Mine doesn’t have any network access. It was probably from 2019-2020 era. I’m sad to hear if they are all networked now.
r/Costco • Any thoughts on pictured air purifier? ->Slightly cheaper option: I use the winix 5500. It has a mega mode (which is loud) that cleans a very large room quickly, or that you can run constantly if the air is really polluted. I have very bad asthma and it was able to clean my house air during forest fire season. It worked so so well. We have had the same one for 4 years, running constantly, with no trouble. We do not have the smart version, which I would be wary of (more parts to break). Bonus: it is on sale right now Edit: I think this is the one we have up at our cabin. It doesn't get used as heavily so I can't speak to longevity, but we bought it used and it works perfectly. Sorry the link is chaotic. https://www.winixamerica.com/product/c535/?_gl=1*14sla5r*_up*MQ..*_gs*MQ..&gclid=Cj0KCQiAyc67BhDSARIsAM95Qzsi-b5swDVaTVYvius-k4yc29_yya6emNoU-ixOlYQgQhYoDvVP6I4aAovaEALw_wcB This is the one we have at our house: https://a.co/d/e2W3sJ8
r/moderatelygranolamoms • What are the best air purifiers for home to enhance indoor air quality currently? ->HEPA and carbon. The Winix 5500-2 is a really good one for the price ($133 currently): https://a.co/d/2JXjKYa You can turn the plasmawave thing off if you're worried about ozone.
r/ucla • To those stuck on campus, let's get an air purifier. ->Check Facebook marketplace, I got 2 lightly used winix 5502 air purifiers for $155 they retail for about $180 each
r/AirPurifiers • Just tell me what air purifier to buy! ->Check out Facebook marketplace, I just picked up 2 barely used Winix 5502 for $155
r/AirPurifiers • Woke up to allergies. Went online and saw this one sale at Home Depot ->I have two goldens. I have a pet grooming vacuum that I use on them about every day (you know the kind that allows you to brush them and then click a button and it sucks hair into the vacuum -amazon). I then have a shark vacuum that has excellent suction power, I vacuum just about every day, and then we have a few air purifiers in the house that do a good job at controlling odor and does look to pick up some pet hair. I think the air purifiers are on Amazon and are called winix? They dont require changing the filters often at all.. once a year, maybe! Uproot clean products are amazing too. They even sell special drier sheets to help pick up dog hair from your clothes better.
r/corgi • What's your ultimate setup for controlling dog hair in your home? ->Amazon.com: Winix 5500-2 Air Purifier with True HEPA, PlasmaWave and Odor Reducing Washable AOC Carbon Filter Medium : Home & Kitchen https://share.google/Qoi1QAM9UlG7BfuMF Just take note of the square footage it covers. We have three and will put two in a room to cover cooking odor, or if it just smell a little bit too much like dog 😅
r/corgi • What's your ultimate setup for controlling dog hair in your home? ->I second this. I have the 5500-2 (AM80 actually - but it’s only an aesthetic difference) and the smell in my room drastically changed. Mine wasn’t specifically animal but a culmination of prior animals, general dust, and the related musk from high humidity. I set it facing the registers in the room and it was a game changer. I know it really helped since I had to run the hvac fan constantly to get the humidity under control, which before getting the purifier I dreaded since it made the smells worse. And it makes quick work of my son’s dinner choice consequences (turns red and everything 😂).
r/AirPurifiers • Best air purifier for litterbox odor/pets in 1,100 sq ft home, $200 max budget? ->With that size room I’d probably want to put one in each quadrant but I’m dramatic-your budget may limit you to 2 though, which I think would be the minimum for the room. I had a good time with Winix 5500-2 (mine was AM80 for aesthetics, but pretty much same thing). I have high humidity and also had a bathroom leak and it was a game changer while I was fixing those issues, and since. The 5500-2 and AM80 can still be found, at $205 and $190 respectively. There are newer models that are pretty much the same thing available as well. The 5510 on Amazon for $179, and the 5520 for $199. Somewhere in there is the AM90-same aesthetic of the AM80. 5500-2, AM80, 5510 I believe all use the same filters - so replacements should be the most available. Not sure about 5520-I read somewhere it was smaller, but I think I’ve seen it included in the compatible models when buying replacement filters for mine. There was an older model (5300-2) with a different lower end carbon filter that was cheaper, but I don’t see it available anymore. My mother sent this to my aunt in Chicago as she wanted to start cheaper and be able to replace the filters more often at lower cost. So we know about old Midwest buildings! One thing, sometimes people complain about the “plasma wave” option that turns on automatically which is an ionizer. Apparently it creates a small amount of ozone, so a lot of people turn it off. Something about birds. You can definitely turn it off too if you don’t want it. I actually grew up using full on ionizers as air purifiers recommended by her drs and allergist for my sisters asthma and you can’t beat the smell of sterility they bring.😅 Double check Winix site for pricing too though! I think they are comparable to Amazon, but may also only have the newest models. I also heard there’s a Costco specific model, not sure what that one is. I’d probably go with the two of the 5510s!
r/AirPurifiers • Classroom Purifier Request — Mold, daily use, etc. ->Oh a double check my pricing! I just saw a 5500-2 with the older aesthetic for $152! https://a.co/d/hgis3a1 5500-2, 5510, 5520, AM90 are all “color” options in this listing, but they are in fact the different models with the different prices. https://a.co/d/aBUYET8 am80 that I bought

r/AirPurifiers • Classroom Purifier Request — Mold, daily use, etc. ->This I think the only air purifier I'd trust in the case of major chemical removal would be an expensive IQ Air Gas. That said, I've been using Winix for years and I love them. They are quiet, work well overall, and are a much better bang for the buck. The 5500 is a better machine for VOC removal as it has a much more substantial carbon filter. I also believe their PlasmaWave tech does help too. I understand the science behind it, and in my experience it seems to help in the long term.
r/AirPurifiers • Winx air purifier ->One of the best for the money is Winix, as they are AHAM verified for their CADR, of which are higher than most. However Blueair and Coway are also great options with good performance for the money. They all use quality HEPA filters and most models are Energy star verified too.
