For years, it has been known that a certain spectrum of UV light can be used as a disinfectant. Known as germicidal UV, or UV-C, this wavelength of light has been tested and proven to easily kill and stop the spread of pathogens like the flu. Boasting a 99% kill rate, according to Infection Control Today, UV-C works by damaging the bacteria’s or virus’ nucleic acid—small biomolecules found in DNA—which disrupts its ability to replicate and cause disease.
This has opened up an avenue of new possibilities for disinfection equipment, as it’s an inexpensive way to eliminate airborne or surface contaminants. As HVACs are responsible for cycling the air in your building, it would be smart to have a UV light sanitizer installed in your HVAC. This way, you can improve your protection in the fight against nasty microbes.
