| Customer Reviews: Average Rating:  Rating : - Unit was loud and did not move enough air Purchased unit because I wanted a small filter for dust and pollen for my bedroom. In my previous house I had a much larger unit that was both quiet and effective, but got rid of it when downsizing to a small apartment. This unit was just too noisy, even on the lowest speed, for me to sleep. Returned through Amazon's excellent return policy. + See Full Customer Review |  |
