The study, published this month in Applied and Environmental Microbiology, is the first to comprehensively analyze the effects of different wavelengths of UV light on SARS-CoV-2 and other respiratory viruses, including the only wavelength safer for living beings to be exposed to without protection.
Results show that Airborne SARS-CoV2 was detected in the ward on all five days before activation of air/UV filtration but on none of the five days when the air/UV filter was operational.
