“At first I wasn't sure if this product was going to do anything at all, before plugging it into the wall my bedroom had some kind of smell / odor to it like the air just needed cleaned. Anyways I noticed after the first night that I had no longer smelled that type of smell and it seemed to have gone away. I tossed back and forth the idea of returning the product for something bigger and all but now that the air feels cleaner I am not going to do that. This product is a no brainer if you want the air in any room to feel cleaner and not have any type of smell or odor in that room. I feel it was worth the investment.”
