I have this in my finished basement, which doesn't have any strong smell or anything, but always felt a little stale because there isn't much ventilation. I definitely notice a difference, it's just more pleasant and I don't notice that slight taste in the back of my throat that I used to. It's definitely not silent, but I find the fan to be a pleasant sort of white noise that I might want anyway. It doesn't get in the way of conversation or music.
