UV Lights in HVAC Systems UV light has been used in applications such as water treatment for many years because of its short wavelength radiation between 200-280 nm. It is very destructive to the nucleic acids of microbes, thus preventing their replication. UV lights are often found in the ductwork of an HVAC system before the air handler. The circulating, conditioned air is exposed to the UV light, which then attacks any airborne pathogens by breaking down their DNA or RNA, thus making them inactive. Some HVAC UV light systems also incorporate ionization to eliminate odors and statically charged particles in order to be filtered downstream. The UV lights need to be always on so...
