was this installed in the supply plenum? how much were you charged if you don’t mind answering? i was told around $1000 which seemed lot? and my technician talked about it creating an ozone smell?
see this link for potential dangers:

“UV-C Light
Air purifiers that use ultraviolet light to kill microorganisms (also known as UVGI, ultraviolet germicidal irradiation) only work against certain species. More importantly, they may also have a hidden danger. Small home UV-C air purifiers use a fan to blow air through the purifiers, where pollutants are briefly exposed to UV light while passing through. The hidden danger is not from the radiation (although you do need to be careful when using UV-C light). The danger comes from oxygen particles that are broken apart by the high-energy UV-C light. These atoms then combine again with other oxygen atoms to form ozone. Therefore, UV-C air purifiers are not ozone-free.
Not only do they produce ozone, they are not very effective in a residential setting. While studies have shown that high-energy ultraviolet light kills bacteria, viruses and some mold spores, to do so effectively requires very high-intensity UV light and a long duration of exposure. So these units offer neither the intensity nor duration necessary to be really effective. Plus, they do nothing to remove particles like dust from the air, so they have to be combined into hybrid systems with HEPA filters.”
I did not buy it separately, it came with a unit I bought, I just asked them to out it on my downstairs unit.
It seems to work fine and if it gives me any help at all it’s worth it.
The HEPA system is more useful than the UVC component.
