Its that time of the year again, when I get the furnace cleaned, install a new filter, clean the humidifier ( and install a new humidifier pad), and start it all up. In the last few years, I've seen something called the "Swordfish" advertised. Its an ultraviolet light that is connected to the furnace ductwork and kill bacteria as well as mold that passes by the light. I've read some reviews about it and it sounds as though it does work. However I'm still a little skeptical. Does anybody have one or have any thoughts on it?

Erm, I just ate raw swordfish. I mean, it was microwaved for a couple minutes. But mostly-- ceviche. Am I gonna die? [more inside]
