Definitely Works!!
I love this so much I bought 3 of them.  I was having trouble in my office and suffering from allergies or something in the air.  I bought the Germ Guardian and after letting it run for a full day, I was AMAZED at how much better I felt.  I have not had problems since so I let it run all the time.  I then bought 2 more for my home since I am doing a lot of painting inside and the fumes were bothering me.  It definitely cleaned the air and removed the smells.  I love, love, love this room sanitizer!
