Ultraviolet Air Purifiers

Dear Friends,

We are considering having installed an in-duct installation of an ultraviolet air purifier for our HVAC. This is supposed to kill mold, bacteria, and other germs. Do any of you folks have any experience with a ultraviolet air purifier system? What has been your results? Do they really live up to the manufacturers claims?
Thanks for all of your help!
