I’m seriously allergic to cigarette smoke and the management isn’t willing to enforce the No Smoking clause in our lease.  So I’m grateful I found this little beauty.  I can sleep at night and the clothes in my walk-in closet don’t smell like they’ve been stored in a smoking lounge.  I run it continuously, but mostly on the lowest setting and it’s very quiet.  At higher speeds it has a nice whirrrr that doubles as a white noise machine, muffles neighboring TVs as well.
