So I think this actually does work as I left it going while I was gone for a trip and the place seemed to be actually fresher when I got back. It's a pretty unobtrusive device and can be placed just about anywhere there's an outlet.<br /><br />Caveat - This thing just loud enough to be annoying. It is not for sleeping areas. You may think when you first turn it on, &#34;oh, that's not that bad&#34; and it's not if there's other ambient noise. I have mine in the living room and don't really notice it. It wasn't working out in the bedroom.
