Seemed to help a lot with my spring allergies. Sleep mode is very quiet but I didnt mind the noise level at the higher fan settings either.

I have asthma and these helps so much. It definitely helped prevent flair ups. I 100 recommend this product. It takes so much duct out of the air.

I ordered a unit along with a replacement filter. I've never regretted it. I have asthma and this stuff helps tremendously.

Perfect for a bedroom. The air seems noticeably clearer and fresher.

I keep this on- 24/7 on the first setting. Its quiet. Not completely silent, but I prefer the little bit of blowing noise from this. It does our large bedroom with no problem. There is a night feature and it lowers in sound and fan. I have allergies and recently they've acted up so that I struggle with breathing at night. This unit has cleared the air and I can breathe! Love this and would recommend.

It works. Feel much better

This fan works too well. My cat took a liquid crap in the hall near it and I couldn't smell it (no I don't have COVID).

Good to have.

I like when I put it on high and it works like a sound machine and I wake up feeling rested and congestion free.

I do recommend this product.

Allergies are definitely better after using this

I'm one of those allergy people and I have a cat that sleeps with me. My house is 100 yrs old, dusty and drafty no matter what I do and it's a continual battle. Enter this wonderful WONDERful product. I saw the 60K reviews, read them for an entire day, also saw other articles on top rated purifiers (Levoit always in the list), and decided this was the one. Honestly, it took maybe 3 min to set it up and that included opening the package and removing the plastic from the filter. This Levoit is incredible! Within 30 minutes my room was like new, a Spring day! And at night, I put it into the night mode and it is completely silent and no lights. I tell you, I'm in heaven. In addition, it is ozone free and that makes all the diff in the world to me, a COPD patient. Best purchase in ages. Many thanks to Levoit! A-1

Filters the air quietly unless on highest level. Timer works well and sleep setting is very quiet.
