The primary transmission method for COVID-19 is from respiratory droplets spreading when an infected person coughs, sneezes, or even talks. These droplets are then either inhaled by another person or end up somewhere on your face after touching. Usually, they end up on the eyes, nose, and/or mouth.
However, some studies suggest that the COVID-19 infected droplets could spread through your HVAC system in your facility. This is why HVAC systems not only use air filters but also additional measures such as ultraviolet (UV) lights to improve indoor air quality.
What Does an HVAC UV Light Do?
To improve indoor air quality beyond what filtration and even air filters can do, HVAC UV light purifiers have been developed. UV lights can reduce or prevent the spread of microorganisms in an HVAC system.
UV light has been shown to be effective for sterilization, including germicidal lamps. For air purification purposes, UV purifiers are installed inside air handlers where it can target bacteria, viruses, and mold spores.
Do HVAC UV Light Purifiers Really Work?
Yes, they do. UV light as a germicidal can be effective to decrease fungal contamination inside HVAC air-handling units, according to studies.
With today’s concerns over COVID-19, that’s even more important. While HEPA filtration can help deter transmission, according to Dr. Julian Tang, associate professor at Leicester University and consulting virologist at the Leicester Royal Infirmary, HEPA filters do not capture all COVID-19 droplets. An HVAC system that uses both HEPA filters and UV light purifiers provides better protection and improved air quality.
