Too loud, but the room smells better.
So loud!  I can hear it in the next room. It’s louder than the bathroom vent fan.  It seems to work for odor removal and that’s the only reason I put up with it. We have three, one in each bathroom, but I wish they would be quiet. I have other germ guardian products and they’ve all been quiet compared to this noise maker.
