How Effective is UV Light in HVAC Systems?

Ultraviolet (UV) light emitted in the UVC range has powerful germicidal properties although can be harmful to the eyes and skin with direct human exposure.  UVC light in heating, venting, and cooling (HVAC) systems is a great way to sterilize the air in homes, commercial and industrial buildings without direct exposure.  UV light is proven to be very effective at improving indoor air quality by eliminating harmful pathogens from the air. 

How HVAC Systems with UV Germicidal Lamps Work

UVC lamps which are engineered to produce wavelengths in the 254 nanometer (nm) range are proven highly effective at eliminating any threat from many types of germs and mold.  UVC radiation in that wavelength quickly penetrates the DNA of microorganisms including many types of bacteria and viruses, which renders the cell unable to replicate and harmless.  UVC lights eliminate these microorganisms from the air as well as preventing the buildup of fungi, mold, and mildew. 

Germicidal UV lamps mounted in HVAC systems are proven to sterilize the air as it passes through the ventilation system to improve indoor air quality.  A study conducted by Penn State University and the American Society of Heating, Refrigerating and Air-Conditioning Engineers, ASHRAE, concluded that UV lamps successfully reduced the amount of pathogens and fungi in the air and improved indoor air quality in children with mold induced asthma. 

HVAC systems with UV purification lamps provide healthier, cleaner air and also improve efficient operation of HVAC units.  By preventing the buildup of mold and mildew, HVAC systems operate cleaner and more efficiently, prolonging equipment life.  LightSources provides germicidal UVC lamps for any industry with custom engineered products including phosphor blends to meet your requirements, custom sockets and bases and prototyping services available.
