WINIX 5520 Air Purifier for Home Large Room Up to 1882 Ft² in 1 Hr With Air Quality Monitor, True HEPA, High Deodorization Carbon Filter and Auto Mode, Captures Pet Allergies, Smoke, Dust.

We liked this air purifier so much that we ended up buying three. The biggest deciding factor was cost of ownership—replacement filters for brands like GermGuardian can cost nearly twice as much. The Winix 5500-2 includes washable pre-filters that can be vacuumed, which helps extend the life of the main filters. We also prefer using this larger unit at lower speeds: it’s quieter, uses less energy, and should help the motor last longer compared to running smaller units on turbo. Excellent value and performance.

The Winix 5520 deserves my rare 5-star rating. Everything about this is exactly what I expect. It just works. I set it up next to my 3D printer, and the difference in air quality is noticeable. PROS * It works - air is cleaned efficiently. * Aesthetically pleasing. * It is very quiet. * Setup was flawless and easy. * The unit's auto feature is accurate and trustworthy. * The replacement filters are a fair price, work well and can be trusted. CONS * The app used to control devices is only available for iOS and Android. Windows, Fire Tables, etc. are not available. In summary, I can personally recommend this product.

Two of us in the house suffer from allergies, and so we decided to try the Winix 5510 in our dusty old house (after we'd vacuumed). We were expecting to be disappointed, but after running it consistently to purifier a larger open space at the threshold of a living and dining room, we noticed a reduction in dust motes and pet dander. The air quality has improved IMHO--if our noses and sinuses and reduced coughing are to be believed. The operating noise level is very quiet on automatic and night settings, but it gets progressively louder as you increase speed. We elevated to waist height it really does the job. We don't use the app, but it's a nice feature if you want it. It's light and easy to move, operate, and maintain. Note: There are replacement filters, but make sure you use the correct part number: 1712-0123-00.

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.

We are very impressed so far with the Winix Air Purifier. It is very quiet and does a phenomenal job of removing pet odors and reducing pet dander. We are very surprised how well the auto feature works. It turns on and selects the appropriate fan settings. We have a dog with long hair and live in the Pacific Northwest. Now that the rains have come, he gets wet and the house starts to smell like wet dog. This air purifier really does a great job of neutralizing that odor.

This is my second Winix air purifer. Got the larger one for living room/kitchen area as it is a new building with materials that seem a bit toxic. I run it every day to clean the air. It is large but not heavy. It is easy to use, easy instrutions. The noise level on the two lower levels is fine, but on high is a bit loud. But that does not bother me as I feel it is getting rid of nasty stuff in the air that I need until I can move out/ I tur the level down once the light stays blue. The light goes down after it the air is cleaned but still working to keep things clear.

I returned it hopefully they come to pick it up soon, The voltage is not compatible with my country's power supply! Idk why would they sell it worldwide

Nowhere in the product description does it say that this is a 120V product which most of the world does not use. I plugged it in uae and the unit got busted. Waste of hard earned money 845 dhs and wait time. Worse still no warranty in the UAE. Worldwide buyers be warned and stay AWAY from useless products like this.

A very good air purifier with a washable pre filter and carbon filter.Design is okay. Easy to install .Noise level is surprisingly low and in night it automatically reduces fan speed if auto mode is selected. As for allergens I think it’s doing a decent job.Its a good value product overall. Plasmawave feature actually works and odour is drastically reduced.

The seller is lying; this is advertised to come with a remote control, which is why I chose it, and there is no remote control included, and it cannot be connected to an app. BEWARE - Do not recommend buying this if you require remote operation.

Very well made and really works. The high fan speed settings is nothing really loud, I would compare that to the normal family house noise level with TV on and people talking. For more silenced mode you have fan speed 1 and 2.
