Winix5510 Air Purifier (New Generation of 5500-2 with App Support) for Home Large Room Up to 1881 Ft² in 1 Hr, True HEPA, High Deodorization Carbon Filter and Auto Mode, Captures Pet Allergies, Smoke

The Winix air purifier has completely transformed the air in my home! Within just a few days, I noticed a huge reduction in dust. The air feels noticeably cleaner, fresher, and healthier to breathe.It also does an amazing job at eliminating odors. Whether it’s cooking smells, pet odors, perfumes, or even wildfire smoke, they have been no match — we can’t even smell the smoke indoors anymore, which is a huge relief during fire season. Everything disappears quickly and quietly. The difference is honestly incredible.The unit runs quietly, is easy to use, and has a sleek, modern design that fits in anywhere. If you're looking for a purifier, this one is a total winner. I didn’t realize how stale my air was until I experienced the Winix difference — now I can’t imagine living without it!

Nice unit, really quiet and really good air flow on high for a hepa filter. The size is just right. It's been on for a month collecting lots of dust and no problems. The orange light comes on when I light a candle so I know it's working. The air smells better and I notice less dust. So far it's worked great. Opened the box, inserted the filter and turned it on. Easy enough.

I have extremely narrow sinus passages so it takes very little to irritate them and plug them up. It took years for me to figure out that air pollution has a lot to do with it. This purifier has definitely helped. I keep it on the 3rd speed throughout the day in between the living room and dining room. A half hour before going to bed I move it to the bedroom and set it on turbo. When I retire for the night I turn the speed down to the second from the lowest. I have found that the bedroom door needs to be shut or it doesn't do the job but turning up the speed isn't an option since we're both used to quiet. It isn't that loud but just a bit more than we can sleep with. In the morning I put it back in the main area and turn it on turbo for at least an hour to catch up again to the pollutants. I also bought a pollution monitor at the same time so I can see the actual results in the levels of pm2.5. The reason I don't trust the amber or red colors which are supposed to be an indication of moderate or unsafe levels is, if I move it to an office at night the level shows red even when the monitor shows very low levels of pollution. After about 20 minutes it changes from amber and back to blue. When I move it back to the main living area again, after just the 20 minutes, it goes to red again and then amber and about 15 minutes later it's back to blue. In those 20 minutes the furnace has not come on, a door hasn't been opened and I have been the only object that has even moved, and that was just moving the purifier. The pollution levels also haven't changed in those 20 minutes according to the monitor. Also, certain smells can change the color to red and that includes good smells like fresh baked bread. In summary, I'm glad I bought it because it definitely does as advertised and easily for the 360 sq. ft. but due to the warning colors not making a lot of sense and the auto setting based on that, due to my condition I'd never leave it on the auto setting. One last thing, I was thinking the first filter didn't need to be cleaned for 3 months but when I looked at the instructions again I saw where it was supposed to be cleaned every month. I was shocked at what this filter had collected. It reminded me of a lint trap on a clothes dryer. A lot of this was what we had been breathing in. I have a second smaller purifier coming for the bedroom so I don't need to keep moving this one back and forth.Update: After more than 1 1/2 years it still performs flawlessly and easily does the job. I have not had to change a filter yet. I just vacuum both sides of all the filters and I'm good to go.Update: I have been using this purifier for almost 5 years and this year it has really been invaluable with the smoky air from the Canadian wildfires. I live in SW MN and we have had days where the AQI has been in the red zone with pm2.5 readings well over 160. This thing has 4 speeds and I typically leave it in the 3rd due to it still being quiet but with the air as bad as it was lately, it wouldn't keep up. The pm2.5 level got up to 144 in the house but after running the purifier on high for 8 1/2 hours, it was reduced to just 5. This purifier works great for the dining room, living room and kitchen and we have a different smaller one for the bedroom. I do have a monitor for checking the pm2.5 levels. Also, I have not had to replace a filter yet. The only thing I do is vacuum the filters whenever I feel they need it. If this thing dies anytime soon, I will be replacing it with the same one.Update: I've now had mine for 5 1/2 years and it's still working like new. I've never had to replace or wash a filter. I just vacuum out all 3 filters about once per month. I don't live in a smog filled city so that might help but we did put up with the heavy and unhealthy smoke from the Canadian wildfires last summer and it handled it just fine.

The Winix 5510 is a powerful air purifier that's quiet, easy to operate and packed with features. However the app and documentation leave something to be desired.The 5510 seems to be some kind of one-off middle model that doesn't appear on any of the company's main brochures. I usually see this sort of thing when a model is made for a specific retailer like Costco, or when it has a unique or experimental feature not common to the rest of the product line. If you go to the Winix website, you won't find this one by browsing - you have to put the model number into the search to bring it up. Why is this relevant? If you search for replacement filters using this model number, you won't find many that match, but as far as I can tell the filters are identical to the ones used by the 5500.The packaging did a great job securing the cleaner and it arrived without any damage or issues. No assembly is required for setup, but you do have to remove the cover, the dust mesh and the two filters so you can take them out of their plastic covers and reinstall them.The machine is easy to operate, but the instructions provided are terrible for a couple of reasons. Firstly, the instructions don't actually tell you how to use the device. They explain how to install and replace the filters, and they explain the function of "Auto" and nighttime mode, but they don't tell you how to actually set auto and nighttime mode. It's not difficult to figure out, but the instructions have one job to do, and they spend more text on compliance garbage that users don't read or need, and none telling you how to operate the device. There's a light on the front center of the device. The diagram that labels the various features does not tell you that this is the air quality indicator. There's one sentence that mentions the air quality light in relation to something else, but absolutely nothing to tell you what the different colors mean. Again, it's not hard to figure out that red is bad and green is good, and other colors are something between, but the instructions have a single job and completely fail at it. Lastly, the instructions do not tell you want replacement filters are compatible. Instead they show you in about three different places how to contact the manufacturer to buy the filters from them.A huge part of the reason that I bought this Winix 5510 is because popular brands are easy to find replacement filters for. There's a huge secondary market making knockoff filters that will work mostly as well as OEM.The practice of gatekeeping replacement parts is kind of underhanded in my opinion. I get that low quality replacement media might diminish your opinion of the whole filter, but when you pay half price for something you should know what risk you're taking.For the record the HEPA filter provided is labeled "2522-058-01 Rev.01S" and the carbon pre-filter is labeled "2523-0053-00" Replacements are sold on Amazon, but the Amazon search won't bring them up for some reason. If you use google and search for "116130 5510" it will bring up links back into Amazon for replacement media.The filter has an app control instead of providing a remote control. On the one hand I can understand that having a remote control is just another object that's a hassle to keep track of or to lose and an app can fix that because you're much less likely to lose your phone, and even if you do, you can always install the app on a new phone. Unfortunately Winix decided to take advantage of the app to force you to create an account. At best every account you create for an app like this is a security liability and widens the attack surface for identity theft. When an account gives you significant benefits in return for the sacrifice of your privacy, I can understand it, but when it's just so you don't have to walk across the room to push one of four buttons, it is definitely not in your best interest to create it. The manufacturer should have made the app without a login or account requirement - many manufacturers do. For this reason I have not used the app and cannot recommend its use.The primary reason I purchased this air purifier was to clean the pet smell from a room in my house. I have not had it long enough to say how well it performs, but I will say that the air quality filter went from red to green after a short while but had not significantly reduced the smell. I will update the review after I have had more time with it, to confirm whether it does significantly clean the air in the room.The filter is very quiet unless you crank it up to "Turbo", and even then, all you really hear is the rush of air.For some reason the cat is very attracted to it and keeps reaching up to try to look into the air outlet.With sturdy construction, easy configuration, quiet operation, automatic air quality detection, replacement filters that are likely to be available even after a couple of years and light detection to automatically enable night mode, this filter has all of the features I could ask for except for an app that doesn't require a wholly unnecessary login.
