Hygeaire UV Air Disinfection Units use indirect germicidal UV irradiation to purify the upper room air in occupied spaces, reducing the risk of cross-infection and exposure of occupants to infectious airborne microbes. Simple to operate, these highly compact fixtures are designed to protect the UV rays that are projected across the upper room air, thereby destroying bacteria and viruses that are carried into the UV field by convection currents or air circulation. In addition, the company reports Hygeaire UV Air Disinfection Units are economical and require very little power to operate. They disinfect air in seconds while providing continuous disinfection without special attention. Constructed of corrosion-resistant 304 stainless steel and aluminum construction, Hygeaire requires very little maintenance other than yearly lamp replacement and periodic cleaning.
