Study shows UVC light destroys 99.9% of virus

A separate and groundbreaking study carried out by scientists at Columbia University Irving Medical Centre earlier this year offered perhaps the most promising insight into how COVID might be destroyed.

Researchers there used far-ultraviolet C (UVC) light at a wavelength safe for humans and discovered that it killed more than 99.9 percent of coronaviruses found in airborne droplets.

The coronaviruses that were destroyed are similar to SARS-CoV-2 that causes COVID-19.

Talking to Health Europa at the time, David Brenner, lead author of the study, explained: “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.”
