UV lights kill germs and bacteria in your HVAC system, but they won't remove dust. Filters and sealed ducts handle dust; if you want better air quality, upgrade your filter or add an air cleaner.
UV lights actually take care of bacteria growth. Anything on that coal on the unit, it's not going to help your dust problem. When you look at these contamination levels, you're looking at dust particles, germs, bacteria, and then you're looking at odors. So it's going to handle germs, bacteria, which is a level two, we call it. But level one, dust and particles is really handled by the filter. There are some better filters you can get. Also air cleaners you can get to help that problem. And also when we look at a duct system, a lot of the dirt and dust come because that duct system is not sealed. So you can actually seal your duct system to stop that from causing some dust problems. Now, you're not going to totally eliminate dust. It's not going to happen. But you can improve the chances of not having so much dust. UV lights will not get rid of dust.
