Why UV Light?
A Well-Established Technology
For over a century scientists have known that UVC light (254 NM) disrupts the DNA of microorganisms which prevents them from reproducing, effectively killing them.
Germicidal UVC disinfection for HVAC is now recommended by the CDC and ASHRAE for use in hospitals, schools, and hotels, and is an obvious choice for any environment where indoor air quality is critical. The technology is also commonly used by the food industry and water treatment systems as a chemical-free means of purification.
A Cleaner Air System
Installation of a germicidal UV light inside the air system inhibits the growth of mold which saves energy by allowing the system to operate more efficiently. A cleaner system also requires less maintenance.
How UVC Works
Germicidal UVC light penetrates the cell walls of microorganisms causing cellular damage, which kills them by preventing them from reproducing.
Spectrum
The germicidal UVC light spectrum is approximately 200 – 300 nm, with a peak germicidal effectiveness at 254 nm.
Inactivates SARS-Cov-2 In 0–3 Seconds
Fresh-Aire UV commercial disinfection systems for HVAC achieved 99.99% neutralization of the SARS-CoV-2 virus in 1 second on test surfaces in a laboratory setting at a distance of 9”.
In scientific studies UVC light has been proven to inactivate all types of airborne biological contaminants.

Commercial Applications
Now, more than ever, indoor air quality is critically important for commercial and public facilities of all types. Fresh-Aire UV germicidal UVC light systems reduce the risk of airborne infectious diseases.
Viruses, bacteria, and mold (like all microbes) have no defense against UVC light, which is present in sunlight but is filtered out by the Earth’s atmosphere. The very short 254 nm wavelength of UVC light is able to penetrate the cell walls of microorganisms and disrupt their DNA which inactivates them.
Benefits of Commercial Uvc
- Improves indoor air quality
- Saves energy by reducing biofilm on coils
- Significant savings on coil, drain pan, and plenum cleaning
- Pays for itself – quick return on investment
- 24/7 operation
- Reduces exposure of workers to cleaning chemicals
- Extends the life of the HVAC system
Biofilm On Coils
A coil-mounted system saves energy and maintenance costs associated with commercial HVAC. A biofilm of only 0.002” can reduce efficiency by 37%! UVC germicidal disinfection is the most cost-effective and practical solution.
