Odor remover!
We use this in a 10 x 12 bedroom that once had fire damage from a chimney fire. Even after killz paint,new hardwood, new fixtures, central air running, we could still smell it a little in one corner of the room. We recently had a baby and the newborn being in the room with us made me finally try this,  and it worked! At first I was a little uneasy about having something plugged in and running 24/7, but it only works well if running at all times.  It does put off a little bit of light and it sounds like a small fan.  So it's not super quiet, but the white noise is good for the baby anyway so I enjoy it. Overall I'm very very happy with this!
