    • Works well for pets
Color: Black Pattern Name: Air Purifier
I really like this purifier. It works well for pets. I Have rinsed and wiped the first filter several times and the inner filters still are clean. 3 dogs and two people in the home. On high it blows a lot of air. On the next level 3 it works perfectly. Not too loud but very effective. It helps with pet allergies and stops the sneezing and watery eyes. It definitely removes dander, dust, and other allergens well. ... show more

    • Super clean air purifier with unique features
Color: Polished Charcoal Gray Pattern Name: Air Purifier
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. ... show more

    • Keeps Wildfire Smoke Outside
Color: Charcoal Gray Pattern Name: Air Purifier
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? ... show more
