A short single-speaker explanation (YouTube video) arguing that UV light, applied in HVAC systems via a coil scrubber, prevents microbial growth (mold, mildew) on indoor coils and thus eliminates damp, dusty, musty odors. The speaker uses sunlight/mat analogy to show UV prevents growth and recommends bringing UV into the air handler to stop the smell.
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, right? So in the indoor air environment, in the air handler that is not present, so we have to make it present with UV light. UV light will solve that problem. So the same power, the sun, the same energy that holds, we can bring it into your system and that will stop that damp, dusty, musty smell.
