I bought this because in my area there was a strong foul odor due to a spill of a chemical. We decided to make this purchase to clean the air in our home. It works really well and i am so glad we bought this product. We actually ended up buying 2 because we have a large house. Would recommend this product.

Can hear it on sleep mode. Love that it can be controlled with the app. App is easy to use and I have not experienced any bugs so far. It works. Can’t complain no got it on sale. Using it for my bedroom now but bought a bigger size for when I move into a bigger space.

This unit does a great job. If you vape indoors and this is on auto you will drive it crazy = air quality indicator goes to 999,,, fan at full speed. $50 for a filter well it's been 8 months and I have 39% filter life according to the app. It's been mostly off the past 6 weeks with the warm weather-- windows open and such.

Its honestly great, it pretty quite for how much air it moves which is awesome. The smart features are kind of gimmicky but i do use it for scheduled turn on and off. Overall id say if you can snag it for under 200 then you wont be disappointed.

This was one of the best purchases I ever made! My daughter has respiratory issues and our house was so dusty no matter how much I cleaned. Within a few hours this machine has purified her room and she has not coughed at night since.

I bought this to help my allergies. I like that the filter lasts so long, and that it will tell you when to replace the filter. It is super quiet, and I always leave it on auto. It seems to detect impurities in real time. It's always changing fan speeds whenever it is needed, but most of the time it is on the lowest speed, and you don't even notice it.

Air Purifier does a great job!! We got the larger one for our living room and this one - Pro 400s - for our master. We love that we can control them with our smart phones and Alexa. We will probably get another one for our son's bedroom in the future.

Purchased back in Oct '21 for my dad, who completed radiation in Dec '21, so that he could have the 'cleanest air' possible.
I have noticed a great difference in dust and dog hair (we own 3 dogs), so I bought a couple more purifiers for around the house. I would definitely recommend, and it was easy to set up on both phone and in the house.

It is very easy to use, and I like to use it at night.
Typically, when the sunlight enters my window, I can see many dust particles... that's just the way the world is, right?
Wrong! After using this air purifier, there are never any particles in the air! I can SEE that it's working.
I love using it at night.
