In addition to mold prevention, UV lights can also improve the overall air quality of a building by killing bacteria and viruses. This can be especially beneficial for those with respiratory issues or weakened immune systems.
Overall, the use of UV lights in HVAC systems is a promising solution to combat mold and improve air quality. As technology continues to improve, we can expect to see even more advanced UV solutions for HVAC systems in the future.
The Science Behind UV Light
What Is UV Light?
UV light, or ultraviolet light, is a type of electromagnetic radiation that is not visible to the human eye. It falls between visible light and X-rays on the electromagnetic spectrum. UV light is categorized into three types: UVA, UVB, and UVC. UVC light, with a wavelength of 200 to 280 nanometers, has germicidal properties and is commonly used for disinfection purposes, including HVAC systems.
How UV Light Affects Microorganisms
When UVC light is used in HVAC systems, it penetrates the cell walls of microorganisms such as mold, bacteria, and viruses, disrupting their DNA and preventing them from reproducing. This effectively deactivates and kills the microorganisms, helping to improve indoor air quality and reduce the spread of airborne contaminants.
