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?

A really good air purifier with some unique features. In terms of noise, it is among the quietest at about 60 DB. Obviously there’s more noise the faster the fan spins, but in automatic mode, it senses the amount of gluten in the air and adjust the speed automatically which means most of the time it will be running at low speed unless there’s a lot of dust in the air. You can download an android or iOS app to control the fan speed and to see how much dust it is seeing in the air. You can also set it up for Alexa or Google Home to be able to control it through those devices. One need feature is being able to ask Alexa for a reading of air quality from the device. You can also enable an automatic sleep mode, which basically keeps the device on auto fan mode where it senses the amount of dust in the air during daylight, but when the device notices that the room is dark at night, it will put the fan speed to its slowest mode to ensure that there’s minimal noise during nighttime hours. Once the room is lit again and it is daylight the device will automatically switch to auto mode and if necessary, increase the fan speed to pull in more air if it detects an increased amount of dust. These are the main features of the device, but the other thing that I liked about it compared to similar models from other brands is that they say the standard filters it comes with should last 12 months where many other brands recommend changing filters after three months. This is probably because the HEPA filter that this device comes with is thicker at about 1 inch compared to what I have on other air purifiers filters that are generally 1/2 inch or less thick. I have not yet replaced my filters, but with an estimate of one year it should not be a substantial yearly cost because filter filters run around $20. And I say filters because as you can see in the images for the product, there are actually two separate filters that work together one is a white HEPA filter to filter out particles. The other one is a black carbon filter, which filter filters out smell smells. And holding both of those filters in place is a screen which is washable that is meant to capture, larger dust particles or pet hair before they hit the main filter filters. Overall, very satisfied with this device and the only thing I can’t really comment on is how long it will last as I’ve only recently started using it.

I real like this purifier. It works as described and is quiet. I don't even hear it running in the living room. The filtering lights will change from blue (which is good quality air) to orange or red to show it is cleaning the air, then back to blue. The night light shutoff works very well. The outer cover is a course filter that is washable as well as the first inside filter, then the caracol filter, then the HEPA filter. All are easy to change, and you can order them on Amazon. We have definitely noticed our running noise issue greatly improving. I keep a clean house, but even our daughter has noticed the air quality being greatly improved. Highly recommend this air purifier.

Replacing a 15 year-old unit, next to the litterbox, that had 5 settings, physical power button, and could pass air through very fast, this new Winix is... good but not great? It's the same size as my old unit. It runs quiet but to get any worthwhile airflow I had to set it to 75%, and I avoid using maximum. Even then, airflow is less pronounced than the old unit, which was rated for similar sized room too. So I don't think its very efficient at cleaning. But it might be a little more energy efficient, though I'd rather have a power powerful motor than lights. I loved the slow delay in the motor starting. This suggests quality and longevity for the motor lifespan. Plasmawave is an ionization generator feature. It's enabled when the main unit powers up. I turn off Plasmawave as I don't care for ionization. Now, Winix's solution does NOT produce significant amounts of ozone, which is a big plus. So you might or might not want or need it. Look up ionization benefits and drawbacks in principle and decide if you want it or not. Especially if you have pets. Old filters just had a physical button and could be kept off when needed and not drawing current. Not sure why the digital/passive power system is needed, as that always draws current and adds more points of device failure. Hopefully this new model will last at least 10 years so will it be durable? Time will tell. A solution to this is to plug it into a powerstrip. Surprised to see wifi. Why need wifi for something that just sits and blows? Will update this review as needed. I've had it running a week so far. Update 1: air quality light starred going from blue to yellow to blue randomly yet nothing in the area around the filter changed. Looking at other models that just do the job without as many frills.

This is a very good product. It cleans the air just fine. It takes particulates out of the air like it's supposed to. In the morning when there's light shining through the curtains I don't see dust particles in the light rays anymore and that's great because I'm not breathing those those particles. I feel better, healthier. I can't say it's night and day healthier, but the air filter/ purifier is doing its job and I feel good about that. it's a good product at a really good price.

Field Guide to Domestic Happiness Species: Homo sapiens domesticus Habitat: Suburban living room Observed Behavior: The Atmospheric Incident In quiet homes across the world, a curious biological phenomenon occurs. A member of the household, believing themselves alone and unnoticed, releases what scientists politely call a modest but fragrant atmospheric disturbance, also known as a methane bloom. It is often accompanied by two defining characteristics: • a small but decisive sound • a rapid expansion of odor into the surrounding ecosystem The human assumes the event will quietly dissipate into the environment, carried away by the gentle currents of indoor air. But the modern home contains a vigilant predator of airborne impurities. The Winix 5510 Air Purifier. Compact and deceptively elegant, the Winix occupies its territory with quiet authority. Beneath its smooth exterior lies a layered defense system: a true HEPA filter to capture microscopic particles, an activated carbon layer to absorb odors, and the curious phenomenon known as PlasmaWave technology, which gently breaks down pollutants drifting through the air. Ever alert, its internal sensors constantly survey the atmosphere of the habitat, measuring subtle changes invisible to the human eye. Within seconds of detecting an atmospheric disturbance, the machine awakens. Fans surge to life. Air rushes through the filters with the urgency of a wildfire response team. A red light ignites like an emergency beacon. The human sits silently, staring at the glowing red bar, realizing two uncomfortable truths: 1. The event was not as discreet as originally believed. 2. The machine has no sense of discretion whatsoever. For several minutes, the Winix continues its noble work, cycling the air and restoring balance to the domestic ecosystem. Eventually the red light fades. The fan slows. The human exhales in relief, convinced the crisis has passed. Harmony has returned to the environment. Across the room, the Winix sits once again in stillness… patiently monitoring the air, waiting for the next disturbance in the ecosystem. The human, having learned nothing, continues to blame the cat. Nature, after all, is a cycle. Final score: Human 0. Winix ⭐⭐⭐⭐⭐

After much research and reading and watching reviews, I chose this brand and model. I like it because it has a washable carbon filter with actual charcoal chunks, and many other brands do not. I like the Plasmawave to generate negative ions, and I can turn it off if I want. I like the Auto and Night settings and the timer option. I was interested in the remote, but haven't used it much yet. It runs very quietly unless you turn it on High/Turbo, but that is usually for only a few moments, and it really isn't that noisy. Seems very sturdy and well built (apparently in Korea). It is attractive looking and doesn't take up much space. It was easy to get setup, and exciting to turn on for the first time, as I've become a bit obsessed with fresh air. Being that my house is clean, no pets, no smoking, mostly fresh foods and not much cooking, one person most of time, the air is pretty clean anyway. So I wasn't surprised to see the Air Quality Indicator deem my great room to be "fair" (amber colored light) instead of "poor" as you would expect in a home not previously purified. I put it on high, and after 10 minutes the room was "good" (blue light). I let it run on high for another hour, and moved to another area of the large great room area. That room started at good and stayed that way. I then moved it to my bedroom, which started out as at fair, then quickly changed to good. I put it on Auto, and it ran so quietly I didn't even hear it. I kept it on Night mode in my bedroom and it didn't bother me at night at all. The only light that stayed on was the little white night mode light - the air quality bar and all other lights turn off. It did illuminate my room a bit, but nothing that my usually worn eye mask can't take care of. But I will probably place tape over it when I use it in my bedroom going forward. I loved the fresh air scent of the house in the morning after my first night. Moved it to great room again for the day and set on Auto. All still "good" blue color, until I made coffee. Quickly turned to amber "fair", automatically ramped up to fan setting 3, and in 5 minutes the odor was cleared and I was back to good. A little disappointing, I love the smell of freshly ground coffee, but that is the price paid for fresh air. It being hot here, I really enjoyed the slight breeze from the movement of air in the rooms. I found myself turning the A/C to a higher temp because I already had some air flow from the purifier. It is like having a fan on in the room, without the additional noise of 2 units. The instructions were clear, easy to setup, easy to understand how to use. Lightweight for a 60+ woman to carry from room to room. I believe I will get another one for my bedroom, so can keep one setup in the great room as well so I don't have to move it around. Wish it also came in white for my bedroom. I am mostly keeping it on Auto, and Night mode in my room. So far it seems to keep the air nice and clean that way. I've seen reviews where they suggest keeping on Manual so you can run it on fan setting 2 or 3. But since Auto is doing the job, why do that? When I know something may have assaulted the air quality and I want it cleared pronto, I turn it to High myself until clear, and then set back on Auto - only because I'm obsessed right now about clean air. Going forward, I will probably just leave on Auto the majority of the time. If you decide to buy this air purifier, I think you will be very happy with it.

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.
