I have this in the room I keep the cats litter boxes in. It keeps the room smelling more fresh  than without it. I don't use this in a common area just because it runs a little louder than my other Shark brand purifier of a different model. But it works perfectly for this room. I like the features it as, like turning off the panel lights, filter life, and fan speed. It seems the filter life is pretty long, just like my other Shark brand purifier. This is also light weight so easy to move around and it was easy to set up.
