UV lights kill bacteria on HVAC coils but don't stop dust. Derek Cole says dust control needs better filters and sealed ductwork. You can't eliminate it completely, but proper filtration cuts it way down.

You talked a few weeks ago about UV lights in your system. Will that help my dust problem?
Good question. UV lights actually take care of bacteria growth, anything on that coil 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 2, we call it. But level 1 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. But to answer the question, UV lights will not get rid of dust.
