Can a uvc bulb (36w) be installed inside air in duct

How long does bacteria/ mold/mites have to be exposed to uvc to be effective?

I don’t think it’s long at all, provided bulb is installed and working properly. My only experience with them is in water, but that had a pretty constant flow over it and worked well. These air duct units are commercially available in duct, and supposedly help with scent too.

Im guessin this is for your intake duct? Use a hepa filter attached to the intake and that should help with spores and mold. This will reduce your exhaust fans cfm tho.

I use vacuum cleaner bags that I cut up and secure to my exhaust fan and intake fans - I do it to prevent pollen from getting out of my breeding tent or into my flower tent.
