Review on SimPure HP8 Air Purifier For Home Large Room & Bedroom & Office, Quiet True HEPA Filter Air Cleaner For Allergies, Pets, Smokers, Eliminates Allergens, Smoke, Odors, Dust, Pets Hair Dander, Mold by Tiffany Hart

Great air filtration system for small to medium spaces. We use it in our bedroom but I've also noticed a difference on our entire 1st floor (about 750 square feet). Noise level is very quiet. We generally have it running while we watch TV in the bedroom and we haven't had to turn the volume of the TV up at all. We have both noticed a significant improvement in our allergies and therefore with our sleep. We haven't used the sleep mode because it's already so quiet.
