White Papers: UVGI in HVAC Systems for Air Sanitation

Larson Electronics explains the differences between bacteria and viruses and how ultraviolet irradiation combats them. 

Ultraviolet germicidal irradiation (UVGI) can be an effective way to kill bacteria, viruses and mold spores and help mitigate the spread of airborne pathogens. UVGI is used inside HVAC systems in all types of settings, including family homes, commercial spaces such as schools and office buildings, and industrial facilities.

There are two specific methods used in HVAC systems to sterilize the air: coil sterilization and air sterilization. One tackles the contaminants at the source while the other cleans the air that has already been contaminated. However, there are other factors that need to be considered before installing UVGI lights inside an HVAC system, including the intensity of the UV light.

To better understand how UV light kills viruses, bacteria and mold spores you must first understand the various wavelength ranges of UV light as well as the makeup of viruses and bacteria in order to understand what can kill them.

For a more detailed understanding of how UV light, more specifically UV-C, bombards and kills viruses and bacteria, and how UVGI can help mitigate the spread of airborne pathogens please see our latest white paper called The Effectiveness of Using UVGI in HVAC Systems for Air Sanitation.
