Study Proves Far-UVC Light Effectively Deactivate Covid-19

A new study from the researches at Hiroshima University is offering us the first proof that Far-UVC effectively kills COVID-19. With UVC light with a 222 nm wavelength (Far-UVC) being much safer for both humans and animals, we are expecting big things from this announcement.

The study was published in the American Journal of Infection Control on September 4, 2020, titled “Effectiveness of 222-nm ultraviolet light on disinfecting SARS-CoV-2 surface contamination.” The article demonstrated the results of an in vitro experiment of the research team which showed that 99.7% of the SARS-CoV-2 viral culture was killed after a 30-second exposure to 222 nm UVC irradiation at 0.1 mW/cm2.

The researchers, however, suggest further evaluation of the safety and effectiveness of 222 nm UVC irradiation in killing SARS-CoV-2 viruses in real-world surfaces as their study only investigated in vitro efficacy.
