  • Excellent Air Purifier!

    I live in an area that is extremely dusty, and it's fine dust. This air purifier works really well and I like the rotating feature. It is easy to use and the filters are permanent, so no worries with replacement. It's pretty quiet even on high and has a night light. The cleaned air it blows out is really cool. I liked it so well, I got a 2nd one for the bedroom.
