Poor quality product.
Seemed to be good for a small space, after receiving and opening noticed that product looked a little banged up, depsite the package being sealed. When I first plugged it in it seemed to have very little air flow.  Ran it overnight and didn't notice too much of an improvement in the air quality of a small 6' x 9' room.  By the next morning almost no air was flowing through the device.  Unplugged it and checked for blockages, when i plugged it back in the fan would not work at all.  I'm returning and not sure I would like a replacement bc I don't think it's a well designed product.
