Title: I'm a believer.
Review: I am happy with this purchase. I've had it running in the bedroom for 2 weeks and haven't woken up with a stopped up nose, stuffy nose or a sinus headache, (which is new for me) for the entire 2 weeks. I placed it on top of a clothes bureau 2 ft. from the wall and 6 ft. tall and only hear the slightest whisper of sound coming from it.
