New Columbia/Ushio far UV-C study: airborne coronavirus 99.9% inactivated

A report on the latest viral inactivation experiment conducted by Columbia University using Ushio’s Care222® has been published in ScienceDaily, a well-respected online editorial which often features the latest scientific discoveries and other academic news.

In response to a paper published by the university in Scientific Reports on June 24th 2020, the report explains that more than 99.9% of human coronavirus in aerosolized air was inactivated by a very low exposure to 222 nm far-UVC light.

“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,” says the study’s lead author, Dr. David J. Brenner.

The university team is also conducting a separate study with the novel coronavirus responsible for the COVID-19 pandemic, known officially as SARS-CoV-2. Early indications suggest a similar level of inactivation efficiency against the strain which reached pandemic status in early 2020.
