Loud
I can't really tell if this thing does anything to clean the air or not since I keep it in my bathroom where the cat box is. I'd be lying if I said I noticed a huge difference with it plugged in but I keep it in anyway in hopes that its helping in some small way. Its nice that it can be turned sideways or upright. The light is not bright enough to use the bathroom in the dark but its a cozy glow. My biggest problem with it is it is very loud! My son who sleeps in the next room from the bathroom says he hears it at night through the walls and sometimes unplugs it because it annoys him.
