YouTube clip (by Derek Cole) explaining that ultraviolet (UV) light—installed as a coil scrubber or indoor coil UV—prevents microbial and mold growth in HVAC drain pans and coils by killing microbes exposed to UV. The speaker asserts microbes die within about 24 hours if not airborne and uses a household example (placing a mildew-covered mat in sunlight) to illustrate UV’s disinfecting and drying effect.

Strongest bacteria in the world lasts 24 hours. If it's not in the air, or if it's a bug or it's a virus or whatever it is, it's going to die and it's going to sit at the bottom in that drain pan. The way to prevent that from happening is to introduce UV into that system somehow. Now, we do it here with the coil scrubber, which shines on. The indoor coil has the UV power. So nothing can grow in uv. If you want to prove that point, everybody at home has that mat at the front or back of the house that has the mildew, and it's kind of wet and it's kind of damp. Take that mat, stick it out in the middle of the yard in the sunshine for a period of time, and that will be clean and dry, because nothing can grow when UV is present.
