Not what I expected
This is my first experience with this sort of device. I have two dogs and use this in the room with their crate which is a small room, and I don't feel that this is really helping with the dog odor.  If I leave it plugged in non-stop for a few days it seems to help a little but not as I had thought it would, especially since the room is very small. I had thought this would have the room smelling entirely like clean air but it hasn't & there is always a light dog smell remaining even with it running all the time.  It is also pretty noisy. I feel like I should have gone ahead and just paid more for a tower version.
