Far-UVC light safely kills ( or inactivate ) airborne coronaviruses

The researchers found that more than 99.9% of the exposed virus had been killed by a very low exposure to far-UVC light.

Based on their results, the researchers estimate that continuous exposure to far-UVC light at the current regulatory limit would kill 90% of airborne viruses in about 8 minutes, 95% in about 11 minutes, 99% in about 16 minutes, and 99.9% in about 25 minutes.

COVID-19 Powerful Disinfectants, Simple and Studied WHO Formulations

“We showed that both WHO-recommended formulations sufficiently inactivate the virus after 30 seconds,” as Stephanie Pfänder sums up the results. Plus, this does not merely apply to the WHO solutions; rather, their main components, the alcohols ethanol and isopropanol, also showed adequate inactivation of the virus.
