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.

If you are here, I’d be willing to take a bet that you did your research and saw this air purifier recommended across the internet. I’m here to say, the research you did led you to the right place. TL;DR: Amazing, cut down on airborne pet hair, but a bit loud (when running on high) and may need multiple for a living area. Great value for your money. 5/5 ⭐️ UPSIDES: This air purifier is simply amazing. Me and my wife purchased this due to our two dogs (Husky mix and a Shiba Inu) constantly shedding to the point you could visibly see hair floating through the air. While running one of these in our living room (which exceeds the 360 sq. ft. rating of the purifier) is not the end-all solution to the shedding, it has drastically increased the air quality, and after just 8 hours of running, it decreased amount of hair floating around. I had my doubts as air purifiers don’t particularly work to eliminate pet hair, but this puts in the work to bring it back to a manageable amount. We have identified “hot spots” of where the dog hair tends to conglomerate due to fans and the A/C, and decided to place it in one of those areas. Within a half hour, the air quality was NOTICEABLY cleaner and easier to breathe. Me and my wife would walk in the area of the fan, then go to another room and physically feel the difference in air quality. Around the 8 hour mark I opened the front face and removed a significant amount of pet hair that had been built up on the mesh screen. If you plan on using these to cut down on pet hair, I personally believe it would be beneficial to identify those areas where the hair tends to build up to position your air purifiers. I’m not saying that this has eliminated or even cut down on the amount we have to vacuum and sweep, but it has helped with the floating dust and hair that accumulates in the air. DOWNSIDES: Noise. (Potentially) So if you’re expecting this to be super quiet and unnoticeable, I’m sorry to say this may not be it if you’re running this on turbo. If you only need to run this on a low to high settings to help remove small amounts of particulates from the air, it will be quiet. However, for our pet hair removal needs, we keep it on Turbo, leaving it sound a little louder than any average fan you get from the store. If you are okay with a bit of white noise running in the background, you will be fine. The noise is much quieter (borderline non-existent) when running on sleep mode to high fan, which could be enough based on your needs, but is not enough for us. Rated Area. (Potentially) This fan is rated for a room 360 sq. ft. While that is large enough for most bedrooms, it may not be enough to satisfy a living area, especially if your house is open concept. I would recommend considering investing in two fans for a larger room (but keep in mind how loud the fan is). If you think you need multiple for a single room, consider investing in one to start so you can hear how loud it is, if you like it and want another for a second room and a second for the same room, only get one more and see how well you can manage the noise of two running at the same time in the same room. Air Quality Light: The purifier has a built in light indicator to indicate air quality which is nice, but not super informative, as there is no guide to tell you what it’s measuring or what the measurements are… honestly it could just be a light on a timer schedule for all we know, as the manual only says it indicates air quality in “red (poor), Amber (fair), and Blue (good)” VALUE: If you can continue to find this around $150 dollars (how much I was able to purchase it for), the value for the amount you’re spending is perfect. I will try to update this review when we purchase a second system and have it running in the same room as the first.

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.

I've been looking for a whole room air filter for a while, and Winix was the brand that I'd focused on due to the features, price, and filter replacement cost. That said, I finally committed to purchasing this model, and so far it has met or exceeded my expectations. For reference, this is for my 17x20 master bedroom (340 sq feet) and the unit is specced for 360sq feet. I have berber carpet in my bedroom and it's always given off a 'carpety smell', which I think is the backing oxidizing and crumbling with age. It's very noticeable to me but has never been obnoxious, just an annoyance, but finally wanted to do something about it. First off, this unit is about the size of a common room dehumidifier, so it's not small, and not huge. It doesn't weigh much either. The modes work fine, but I'm not sure exactly how it uses the sensor on it to detect air quality. Mine mostly stays blue, but flips to amber and red occasionally. There's very little distinction between the amber and red color also as it's either "Yup, that's red.", or "That sort of looks red." All the air quality mode does is change the fan speed to a faster setting. Within a day or two of using this on the auto setting, the above mentioned 'carpety smell' is all but gone. I keep it on all the time on auto mode, and it mostly has the blue air quality light on all the time, and runs on the low fan setting. At that setting the sounds is barely audible. I'm hypersensitive to smell, sound, and light, so that was very important it checked all the boxes for me to be something I could keep. It definitely does it's job filter the air/smells, the noise is barely noticeable (it does get louder on the higher setting, but that's clearly to be expected), and the lights on the unit are not that distracting. What sealed the deal for me in keeping this unit was the night mode. When it detects low light levels, it flips the unit to a slower fan speed than the lowest setting speed, and turns off all the lights on the unit except the small white 'Sleep/zzz' one. As mentioned, I'm hypersensitive to a lot of things and need total blackout in my room to sleep, and this light is barely noticeable, and the sound can barely be heard on the 'sleep' fan speed. I have this at the foot of my bed, faced away from my bed, so I don't have direct line of sight to the front of the unit. The 'official' Winix replacement filters cost about $50, which to me is a bit high. There are different types of aftermarket replacements, and I cannot attest to those here, but there are a few that appear to be exactly the same as the OEM one. The filter set has a large paper element filter, and a black carbon one that looks like a 1/2" thick plastic rectangle with tons of little honeycomb chambers and granulated activated charcoal pellets. That's what removes the smells and they definitely work. I will be trying aftermarket filters in my unit after using the provided OEM ones once I know how long they work, how well they work, and how long they last. Overall though, this is the best room air filter unit I've seen and I would recommend it. ***Update*** 01/30/24 As an addendum to my original review, the air filter that came with this unit lasted about a year of continuous use before the 'check filter' light came on. When I took the old filter out, it definitely had worked because I could feel and see fine white dust on the main filter, like what you'd see if you cleaned a vacuum air filter. Also not sure how the "Smart Sensor" in this thing works, but it WORKS. If you spray an air freshener in a room away, it picks it up and ramps up the fan. Walk by it after gargling with mouth wash, fan ramps up. Make a toot near it, it definitely ramps up. Nice to have a product that works how it should!

Replaced my Miko in the kitchen with this to handle kitchen odors and it works so well, I bought another one that replaces a Levoit for my bedroom. It is light weight for its size and has a sleek appearance. It is easy to set up and operate. It has a quiet sleep mode which runs on low with no lights. When in the auto mode, a red light is displayed and the fan kicks on when it detects perfume or strong odors and kicks off once it no longer detects it. I have also noticed a lot less dust in the kitchen area. Features a washable pre filter, a replaceable carbon and HEPA filters. I like this better than the Miko IbukiL and the Levoit Core 300s; although these are also nice air purifiers they don't perform as well as the Winix 5510.
