Works great! My daughter had a cough whenever she was in her room for long periods of time. We could not figure out what was causing it, so we got this filter and her cough is gone, so whatever it was, this filtered it out!

Works really well but if you are sensitive to sound, you can still hear it on the lowest setting. That being said it works way better than my old Honeywell and you can feel it circulate the air in your room. Also can connect to Google and Alexa for voice control. I love it. The only downside might be when it comes to replacing the filters. They may only last 8-10 months.

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.

Really love how easy and convenient this air purifier is ! Love the app features and makes it really easy to use . The app even lets you turn it on and off in another state ! Went to Vegas and I could turn it in at home in California

It covers more than one room. It is very quiet on the lowest speed and does not get at all noisy on speed 2. The noise is more noticeable at speeds 3&4. You can turn off the lights. Also, you can control it on your phone. Just hope it lasts a long time. Also, I got a good sales price.

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.

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.

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.

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.

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.

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.
