Fresh-Aire UV says its systems inactivate greater than 99.99% of SARS CoV-2 virus

Cites independent lab validation study in making the claim

JUPITER, Florida, United States, 1 November 2020: Fresh-Aire UV, which manufactures HVAC ultraviolet (UV) disinfection systems, announced that third-party lab tests successfully proved its residential and commercial UVC disinfection equipment for HVAC systems are greater than 99.99% effective in inactivating SARS CoV-2, the virus which causes COVID-19 disease.

Making the announcement through a Press release, Fresh-Aire UV said the ‘SARS CoV-2 Neutralization by Germicidal UVC Light Systems’, study conducted by independent laboratory, Innovative Bioanalysis, based in Costa Mesa, California, validated a four-log, greater than 99.99% coronavirus inactivation in less than two seconds of exposure to Fresh-Aire UV’s germicidal UVC 254-nanometer light systems. The exposure time is comparable to a moving airstream model within a facility’s HVAC or ventilation system, the company said. The lab used Fresh-Aire UV’s ADS airstream and BlueTube XL coil and airstream disinfection systems designed for healthcare, education, office and other commercial facility applications, the company said. The residential and commercial APCO-X coil and air disinfection system also exhibited the same positive results, the company claimed.

According to Fresh-Aire UV, the study is one of the first successful SARS CoV-2 inactivation tests in the HVAC industry and is available at

“Consulting engineers, contractors and facility managers can now confidently specify, install and use our UV equipment, knowing they are being proactive in improving the building’s indoor air quality,” said Aaron Engel, Vice-President–Business Development, Fresh-Aire UV. “Dosage is critical for effectiveness; however, our Blue-Calc, a UVC light design and analysis using state-of-the-art sizing software, can accurately help facility directors, engineers and contractors specify UV equipment for any disinfection application.”

Since the early 2020 onset of the COVID-19 pandemic, Fresh-Aire UV said it has helped provide recommendations for both residential and commercial UV systems. In the FDA-sponsored test published in the American Journal of Infection Control, it said, its systems were used to show the efficacy of UVC light in disinfecting and extending the life of N95 respirators.
