Review on Large Room Air Purifier 3-in-1 True HEPA Filter - Air Choice Smoke Filter - Reduces Pets Dander, Household Odor, Smoke, Dust - Sleep Mode, Auto Mode - Quiet Operation - White by Barb Gordon

I bought this for my office and it's great. This has been the worst year ever for allergies and this silent cleaner has made a difference. Our house is old and although there is no visible sign of mold I sometimes smell musty. After 2 days, with a night break, I no longer smell it and I find it easier to breathe. It's so quiet there, even at the top. I like its size and the very complex filter set. We can also order it for our small guest room.
