UltraViolet Devices, Inc. (UVDI) has announced that its V-MAX UV-C air disinfection technology has achieved 99.99 percent inactivation of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) in a single-pass in moving airstream HVAC testing.
The testing was conducted at Innovative Bioanalysis, a BEI-recognized BSL-3 laboratory in California. SARS-CoV-2 is the primary viral strain that causes the Covid-19 infection, which the Centers for Disease Control and Prevention (CDC) has indicated can be spread by both airborne and surface transmission.
In the independent testing, the technology eliminated 99.99 percent of SARS-CoV-2 in a single pass at an airflow rate of 500 feet per minute. To confirm effectiveness against airborne SARS-CoV-2 in a moving airstream, Innovative Bioanalysis used a HVAC duct test based on a modified ISO 15714 and ASHRAE 185.1 standard. To replicate conditions in a typical HVAC duct, UVDI V-MAX 254 nm UV-C lamps were arranged in a parallel configuration.
“This novel testing underlines UVDI’s UV-C technology’s effectiveness against airborne SARS-CoV-2,” said Dr. Ashish Mathur, Ph.D., UVDI vice president of innovation and technology. “The study results are further evidence that UVDI provides proven airstream protection—and peace of mind—for critical infrastructure globally such as airports, healthcare facilities, schools and government buildings as well as for high-traffic public spaces such as arenas, sports facilities and hospitality sites.”
UVDI’s V-MAX UV-C air disinfection technology works by damaging the DNA of microorganisms and eliminating their ability to reproduce and infect people. UV-C air disinfection product effectiveness against coronavirus is currently supported using established models to estimate the UV-C dose required to inactivate the virus. The BSL-3 laboratory results also confirm the accuracy of UVDI’s proprietary modelling software, which determines custom product configurations for targeted UV-C effectiveness. The software was used to inform the study’s protocols.
“UVDI is committed to doing all we can to help people get back to normal as quickly and safely as possible, whether at work, in school or travelling,” said UVDI CEO Peter Veloz. “Providing clean, disinfected air is core to this mission and relies on the highest levels of scientific proof. We are proud that UVDI’s advanced UV-C air and surface disinfection products have now both been proven to inactivate SARS-CoV-2 in rigorous, innovative and independent laboratory testing.”
UVDI’s mission is to make a cleaner, safer and healthier world through advanced UV-C solutions that disinfect the air and surfaces in the environments where people live, work and play. This Minority Business Enterprise designs and manufactures advanced ultraviolet light solutions in California, applying more than 70 years and three generations of family craftsmanship and care. Two thousand UVDI-360 room sanitizers are used in nearly 1,000 leading hospitals in more than 25 countries, where they have been proven in peer-reviewed, published studies to reduce healthcare-associated infections and deactivate high-risk pathogens. UVDI’s proven indoor air quality solutions are now installed in over 10,000 international commercial sites.
