It's working, honest.
I purchased this to be in the same room as my litter boxes.  It's easy to install, easy to use and easy to forget about.  It makes a low hum/sound but is not incredibly loud or distracting.  For the first week or so I thought it wasn't working properly so I unplugged it and was going to send it back.  I came home after I unplugged it in the morning,and my entire downstairs floor smelt musty and like cat poop.  As soon as I plugged this little guy in, the air cleared.  I don't know what science-fiction magic trickery is going on with this air-sanitizer, but it works.  It doesn't completely get rid of all odor, but it most assuredly cuts down most smells.  I am considering buying another one for my upstairs.  I know that one per room would be most efficient, but I just don't want to put one in a room I seldom use (I'm looking at you &#34;craft room&#34; that is a dumping ground for who knows what).
