Customers are impressed with the air quality improvement and quiet operation of this 22" air purifier tower. Many appreciate its ease of use and odor removal capabilities, along with the added benefit of a UV light. However, some customers express concern regarding the filter replacement cost and its coverage area. While some experienced allergy relief, others found it didn't completely eliminate their allergy symptoms.

    Good product, I bought this to help get the order out from the air. Its as simple to use as a portable fan, just click (1/2/3) to what setting you want and if you want the LED light on/off.

    I would definitely recommend this to anyone. I purchased this for my son's room and he loves it. It makes noise but not enough to disturb your sleep (my son actually needs it to sleep) and not loud enough that you can't hear the TV.

    So I got this for my classroom (middle school science teacher). It has been running for a few days now and is very quiet. Interesting to see how it holds up once I have students in my room, but figure with COVID and middle schoolers, this is a good investment to have.
