I'd wondered about the UV ones as well. Saw an ad several years ago about some sort of uv lightbulb system one could ad to their existing furnace, but couldn't find much info in it.
We have a Whirlpool Whispuresure Hepa filter system and like others have said, really smells fresh and clean when I walk into that part of the house.
