Abstract
UV-C light assembly is designed to kill germs (bacteria, molds, protozoa, virus, and yeast) in the forced airstreams of HVAC systems, thus preventing the spreading of germs into other rooms or spaces. An air-flow activated switch is invented for turning on the UV-C lights when airstreams pass through and turning off when airstreams stop in the HVAC systems. The UV-C light assembly is installed inside duct through air filter's opening. The UV-C germicidal assembly is an easy add-on to an existing HVAC system for indoor air purification. The UV-C light sources are either LEDs or fluorescent tubes.
