Works great, easy to set up and use. Love that it connects to Alexa. So far seems to be reducing the dust build up in our room, we live in the country and the dust is a constant frustration. Also seems to be helping with the dog hair and definitely is helping my husband with his asthma. Happy that we got it.

Excellent air purifier. Originally I purchased the 600 S model, but that was too large for our room. The 400 S looks less overwhelming. I like the automatic mode and also that you can see the number of air particles in the room with the sensor. Using the app is extremely easy, so definitely recommend it.

Quiet, easy to use, and great app integration. You can set it to automatically turn on at specific times or at a set pollution level. I also really like that it displays the PM level inside and the app shows you the PM level in your area, so it’s easier to understand how outdoor pollution affects your indoor air. Bought mine 3 months ago and I liked it so much I bought a Levoit air filter as a Christmas present for my father.

Best air purifier ever. Great for individuals with bad sinus. My daughter had another brand air purifier and she was sick/coughing for months and she went to multiple doctors and got multiple medications and I decided to change her purifier and that's what helped her sinus, she's perfectly fine now.

This unit has worked wonderfully since I got it home and set up. The WiFi connection was easy to make, syncing to my smart phone was seamless, and I’ve appreciated the ability to make settings adjustments as necessary via the app.
After running it on high for a couple glues I set it to auto and haven’t touched in since. I vape in my home and this thing has some a great job clearing the air quickly and quietly.

Bought this to cope with having a litter of puppies. Numerous visitors were amazed at the lack of smell. We have this in a fairly large room, ~1000 sf, and it only take 15 to 20 minutes to clear odors, dust, and smoke. Great purchase.

You clearly feel the difference in the air with this. It makes you breathe better and I've gotten better sleep. Don't forget to open the bottom to remove the plastic wrap around the filter.

This is probably the best thing i bought all year tbh. I wanted something to clear the air cus I was feeling sick at home and my wife and I have no problems. Set the schedule up and even let it auto turn on when needed as well as stop. I’m so tempted to get one for each room lmaoooooo

I bought this because my baby son was congested and thought it was the air quality so I bought it for him. It didn’t help but I still used it. It works great for when I’m cooking. It really helps the air quality in my home

Great! I haven’t had to clean or replace the filter at this time, but it seems very straight forward. The indicator does a great job! I find it helpful to keep track of the particles thru the app. Only negative is if you use it in a room with a humidifier, the laser sensor picks up the moisture as particulates.

I'm really pleased with this air purifier. Having allergies, this helps reduce and eliminate the allergens from pets and household products and dust. I'm considering purchasing one for my work area to help with some of my sensitivities there
