I installed a new UV light air purifier in the home's HVAC system today. I mounted the UV lamp assembly near the indoor coil, where it will effectively neutralize airborne pathogens and mold spores. After securing the power supply and connecting it to the existing electrical system, I tested the UV light air purifier to confirm proper operation. I also installed a viewport to allow easy confirmation that the system is working and provided instructions on when to replace the UV bulb for continued effectiveness.
