Review on Cozmor Air Purifier: Large Room H13 True HEPA Filter with Smart Auto Sensor - Eliminate 99.98% Odors, Mold, Pollen and Smoke, Perfect for Bedroom and Office. Includes Sleep Mode, Timer, and Child-Lock by Molly Carlson

As you can see - IT WORKS. I have several birds in my office and work from home. I thought I just had severe allergies but no! Those dusty bastards have had my eyes itching for months. This picture is after using this air filter for about 3 weeks, usually on low or auto. The highs are a bit louder than I would like, but I leave it on Auto, no problem. Bought one for my basement and one for my "dog room" off the kitchen. I love watching the numbers go up on it especially when I'm cooking because I had no idea how much smoke there was! I've been recommending it on my bird forums for at least a few months. Love it!
