UV-C Light Safely Kills 99.9%

Study shows 99.9% of coronaviruses killed by far-UVC light

The study, carried out by researchers at Columbia University Irving Medical Center, has used far-ultraviolet C (UVC) light, at a wavelength which is safe for humans, to kill more than 99.9% of coronaviruses that are found present in airborne droplets. The coronaviruses are structurally similar to the SARS-CoV-2 virus that causes the novel COVID-19

Lead author, David Brenner, Higgins Professor of Radiation Biophysics at Columbia University Vagelos College of Physicians and Surgeons and director of the Center for Radiological Research at Columbia University Irving Medical Center, said: “Based on our results, continuous airborne disinfection with far-UVC light at the current regulatory limit could greatly reduce the level of airborne virus in indoor environments occupied by people.”
