Excellent  Product, I had my reservations about this air purifier but went ahead and purchased it. I must say I am beyond pleased with it's performance. I have little to no dust/pet dander than I did before. Having two labs and a cat there was plenty of hair and dander prior to the purchase of this purifier. The smell's of cooking and other odors do not linger in my house. It smells clean and fresh after running this for a few hours. Don't hesitate to purchase this, you won't be disappointed. Just make sure you get the right size for your room/rooms.
