Review on Bionaire True HEPA Air Purifier: Advanced 3-Stage Filtration System for Allergies & Pets, Quiet Settings, Medium Room, White by Kerry Johnson

Love this air filter, it cleans the air really well. I use this to keep smoke out of the air, it does its job perfectly in the mid-range and is incredibly fast in the high-end. Love the timer, never have to worry about forgetting to turn it off, which helps extend the life of the HEPA filter inside. it's fairly quiet, especially at low frequencies. The night light is good but I don't use it. The filter can be changed easily and quickly. This appears to be a very long lasting filter, said to be good for 9-12 months. I would like to buy another of these air filters for a different level in my house.
