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

We put one in the living room and loved it so much we bought one and put it in our bedroom. After a few days we noticed that we were starting to breathe better. Put one in the bedroom and we'll sleep better. The dust reduction is fantastic. Our sinuses are more clearly visible and we don't wake up congested. The fan isn't exactly silent, so we set it to medium and it acts as a white noise generator. Changes, but once a year. I highly recommend it.
