The C wavelength of the UV spectrum targets the DNA of microorganisms, destroying their cells and making replication impossible. Directed at a cooling coil or drain pan, UV-C energy destroys surface biofilm, a gluey matrix of microorganisms (bacteria, fungi, debris, et al.) that grows in the presence of moisture. Biofilm is prevalent in HVAC systems and leads to a host of indoor air quality (IAQ) and HVAC operational problems that are sometimes mistakenly attributed solely to mould. UV-C also destroys airborne viruses and bacteria that circulate through an HVAC system.

By applying the power of UV-C at the source of contamination – the HVAC evaporator coils and drain pan – Steril-Aire UV-C destroys the reservoir of microorganisms. Without the ability to reproduce, microorganisms become inactive and harmless. The recirculating air in HVAC systems creates redundancy in exposing microorganisms to UV-C, ensuring multiple passes so the light energy is effective against large quantities of airborne microorganisms. Steril-Aire UV-C delivers the highest UV-C output, driving HVAC system efficiency while improving indoor air quality.
