Put it inside duct work

  Yup, you don’t need to worry about tuning the UV. Just stick broad spectrum UV (excluding the 100-200nm only) in the duct work.

    Is this uncommon? I had UV disinfectant bulbs installed as part of my HVAC installation in my house, seemed pretty common.

      In new installations, but I think it’s only been common for less than a decade. All older systems will not have them unless they were specifically added.

      Two challenges with making this work well. 1) Not destroying plastic and rubber components exposed to the light. 2) Ensuring whatever is passing through the light receives enough exposure. Often they're better at keeping evaporator coils clean than cleaning the air.

        Oh? It makes sense, but I hadn't heard that. Have your read about that somewhere?
