5510 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 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.

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.

We've had one heck of a fire season this year--and if you live in the Western United States, I can already see you nodding your head in agreement. That's probably why you're here reading this review. Thank goodness for air purifiers. Chances are you've already looked at tons of them. You might even be confused as to which one to choose. Hopefully I can help you out with that. In essence, all an air purifier has to do is filter the air and expel it in better shape than it inhaled it. Most units (including the Winix unit here) do this by pulling the air through a HEPA filter--and that certainly helps. If all you're looking to do is reduce dust, you can stop here. Pick a filter, any filter. You'll get the job done. But why stop with one layer of filtration when this unit offers you four? When the air enters your Winix, it will first encounter a cleanable dust screen. This screen is much like what you may have in front of your computer case fans. Large particles get stuck here rather than in your HEPA filter, meaning you won’t have to replace the HEPA as often. In fact, Winix recommends replacing the HEPA once a year; you may have noticed that other brands recommend changing filters every three months or so. That’s why, and it serves as Layer One. The next layer is a honeycomb filter which is filled with activated carbon. You see, HEPA filters alone won't eliminate odors. Just like how activated carbon will remove odors from fish tanks when used as part of the tank's filtration, it also removes odors from the air. Pet dander, wildfire smoke, a certain someone’s love of gassy foods… yeah, you’ll like this function. That’s Layer Two. Layer Three is the HEPA filter itself. Small particles you may not be able to see--but will still do a number on your eyes and sinuses--get stopped in their tracks here. Layer Four is a negative-ion filter that Winix calls “Plasmawave.” Without over complicating the science behind it, this feature will make it harder for viruses to spread and will cause smaller particles to sink where they can be collected easier. This feature can be turned off if you don’t see the need for such thoroughness or perhaps you’re skeptical of the process, but I strongly suggest leaving it on. When it’s time to change (or clean, in the case of your dust screen) your filters, getting to them is easy. The entire front panel is held on by magnets (better than plastic tabs which can break over time). The filters themselves are easy to find right here on Amazon, and they are reasonably priced. You’ll be switched over in minutes. Your biggest hassle just might be tearing your new filters out of its packaging. Now let’s talk about features. For the vast majority of the people, simply hitting the “auto” button will work. This unit has an air quality sensor, and it will automatically increase its fan speed when it senses that your air quality has declined. Once air quality improves, it’ll slow down its fans. It’s a set-and-forget type of thing. For those who are more hands-on, you can bypass the auto mode and choose your own fan speed. This is useful if you’re running this unit in a room that needs more “reach,” or if you find the white noise of the fans to be soothing. On maximum speed, the unit is still quiet enough to hold a conversation next to it—a box fan is far, far louder. The filtered air is pushed upward, where it can more easily circulate in the room without diluting the denser polluted air it has yet to filter. This helps the purifier do a more efficient job. The air quality monitor lets you know what your room’s air quality is by showing you one of three colors: Blue means your air quality is good; Amber means it’s… well… mediocre; Red means bad. Pretty easy stuff, and easy to see from across the room. The various functions and features are backlit, so even in a dark room you won’t have any trouble selecting what you want. For those who are bothered by the indicator lights, there’s a night-time mode which turns them off. The unit itself is well thought-out and constructed. It doesn’t draw attention to itself, and will blend with most any decor. There’s no remote control that you’ll never use, and the controls are so well laid-out you’ll very likely never need to go digging around for the manual. My brother-in-law owns this unit, and it was on his recommendation that we ordered ours. We liked our first one so much, we quickly bought a second unit to go in our daughter’s bedroom. The difference has been striking. Now we only have to deal with wildfire smoke when we venture outside. The dry eyes and sniffles have reduced dramatically. If that sounds like the kind of world you wish to create for yourself in your own home, why not place your order today?

I recently purchased the 5510 model to replace an older 5300-2 unit purchased in Oct 2020 that had increasing noise from possibly lower quality bearings (I had a total of 3x 5300-2 units purchased in 2020 and only 1 had the bearing noise but was more frequently run at the highest setting). The good - works as well as older units, it seems slightly more fan noise at the "blue" auto setting vs the 5300-2 but also seems to be maybe a result of a higher airflow, possibly to improve cleaning performance and is still very quiet.. Air filtration and sensing bad air seems as responsive as the older 5300-2 so no complaints there. the tldr of why 4 over 5 stars is a simple light sensing for the "sleep mode" since I am a gamer and prefer a lower light environment and this purchase was for my home office/gaming room. The night mode activation level compared to the 5300-2 seems like the sensor was calibrated on users who prefer offensively bright room lighting. In my case I can switch my bedroom 5300-2 unit to my home office and the new 5510 unit will do the job just fine as my bedroom air filter because it does match the older 5300-2 night mode quiet noise level. I am a bit uncertain about the carbon beads pre-filter vs the older 5300-2 "4 sheets of the carbon mesh pre-filters to change every 3 months" but that is a follow up review update for sept 2026.

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.
