Works well on pet odors.
I got one of these for the room where the cat's litter box is and it improved the air quality considerably - of course, nothing could eliminate the odor up close, but now at least I can walk by the door without smelling it. I got a second one to cut down on the doggy odor in my bedroom and it has done an excellent job with that. I've tried larger and more expensive air purifiers before and didn't think they did much, so I'm really impressed with this little unit. The only thing I don't like is that I have to unplug the one in my bedroom at night in order to keep the room as dark as possible for sleeping.
