Not quiet
I have had this unit for a couple months and it is still going strong.<br />I use it in the bathroom where the cat litter box is. She her box is kept as clean as those things can be there is never much odor. However what odor there is this thing helps wil. Occasionally need to run the bathroom fan to help out but that is not a big deal.<br />The reason why it has 3 stars is that it claims to be whisper quiet. This is just a little less noisy than the bathroom fan. I can hear it running when I am in other rooms not attached to that one. I wish it were quiet. I would buy one for each room if that were the case.
