I am sorry George, but that machine will not kill dust mites, and definitely will not kill bed bugs. Ultra Violate light will not kill multi celled creatures like dust mites, and Bed Bugs. It will kill bacteria, germs, mold spores, etc., but these are very small compared to a dust mite let alone a bed bug. Also the light has to be on the thing you are trying to kill for 20 to 30 seconds. Plus the light has to hit whatever you are trying to kill, so if a germ is on one side of say a thread then it will be in the shadow of the light and not effected. There is no penetration with UV light. The EPA directed one of the companies that sell mattress cleaning businesses to stop advertising that UV light killed dust mites. They stopped for awhile but I understand are back at it again, but not quite as open about it as they were before. We did quite a bit of testing ourselves with UV light for our mattress cleaning packages we sell, and settled on dry vapor steam.
