Title: Quiet and Efficient Air Cleaner
Review: I purchased one of these, but the company shipped two (for the price of one) by mistake. I corrected the mistake and paid for the second unit, deciding to use the second one in another part of the house. These units are super quiet. They have reduced DUST in my house, and with two cats, I have noticed fewer problems with allergens from cat hair and cat dander. I'd recommend this air cleaner highly.
