Great little Guardian
Works great and takes out musky odors with no problems.  Have this Germ Guardian in the closet upstairs where our air handler is.  This closet usually has a musky odor form the constant water in the pan, and now I have controlled that with is product.  A little work horse.  Bought extra bulbs for it but have not had to change it as yet.  This unit runs 24/7.  Strongly suggest considering buying for removal of unwanted odors although the unit has other uses as well.
