Gets rid of smells.
I have a very large bird cage and even though I clean it regularly it can get smelly, so I plugged this into the outlet by the cage to see if it would help. You can hear the faint sound of the fan running when it is plugged in, so you know it is working. After a few days of running it, I definitely noticed that the birdcage smell was gone. This air sanitizer really works. I have tried those air cleaners that have filters, but this worked much better, and no filter to worry about.  The GermGuardian is rather large so it basically takes up both outlets unless the other cord has a very slim plug, and it says not to use it with an extension cord. Germ Guardian needs to have an open clear space around it for air flow. So be sure you have an outlet that is in an open area to use it. I really am impressed with how well this clears the air.
