Has anyone ever used a Germguardian Pluggable UV-C Air Sanitizer? http://www.amazon.com/germguardian-G...+Air+Sanitizer

It's supposed to kill airborne germs and mold spores. However, I am reading it is slightly loud. I plan to use it in a bathroom, but I would like to know if anyone here has used it. I would especially like to know how it works on odors. Thanks in advance.
