    This is a nice Air Purifier, very quiet and seems to work well so far. Price was very reasonable at Best Buy. I have an Air Quality Monitor and notice that the particulate pollutants (PM1.0, PM2.5, PM10) readings in the room lowered since I started using the filter. So, it is definitely working. Easy Wi-Fi setup and app and works well. The manual settings on the purifier are straight forward and easy to use. The replacement filter is a bit pricey, but it seems to last for a long time (6-months) from the reviews. So far, I like it and would recommend it.

    It works really well! I do like that it automatically increases the fan speed when there are things in the air such as smoke from cooking. App makes it possible to make a schsdule and don't need to worry about turning it on/off.

    I keep this in my cats room, keep it on most of the time and I think it works great! Imagine a room with 5 cats… yeah, but with this I feel as though the smell is definitely not as strong. The app is super easy to controlas well, super simple.

    The Levoit - PlasmaPro 400s Smart 403 Sq. Ft True HEPA Air Purifier delivers on all accounts. It delivers cool clean air, and can be conveniently controlled with the VeSync app. I also like how light it is to move around to different rooms. I like it so much I might buy another one for our second floor.

    This by far is my favorite unit. I love the cage that shows you how clean there is. After we had plugged the unit in it did not take but a couple to a few hours to breathe clearly. It also helped with my sleep. Also this has helped my pets. Especially my oriental short hair feline. he is not showing signs of asthma anymore . I will buy another unit. Thank you Levoit- to bad your other smaller units do not share the same capabilities. Let me add this is a HEPA 13.

    Love our hair filter! It gets the job done whenever the air quality drops it automatically turns it up and gets it back to green. Highly recommend getting a replacement filter too!

    As a smoker, this air purification unit works great, eliminates smoke in no time. I have it set on auto and it fires up immediately after I lite up. Have noticed a big difference in dusting my place also. A little big for my studio but well worth it,

    These things are great, I own 2 of them. We've noticed we have less allergy symptoms when we're running these in our house and we've noticed less odors overall. I use to be able to smell food cooking in my basement, but with the air purifier running down there the smell is significantly less. The controls on the device and in the app work well.

    Really like this air purifier. Have one upstairs & one downstairs. Reduces the pet dander in the air. Love the fact I can control from my phone, especially when cooking so I can increase them to remove odors from the house.

    This is a top-of-the-line air purifier. The app works great and is easy to set up. It lets you know how much air it's cleaned and continuously monitors the indoor air quality.

    We have two of these in our house. It made it easier to breathe by the second day with it. It also has cut down on the dust that collects on the furniture, now less cleaning time means more playtime.
