"Far-UVC light is a promising new technology for reducing airborne virus levels in occupied indoor spaces, but its effectiveness has not been evaluated in real-life scenarios.

A study by Columbia researchers now shows that far-UVC light inactivated nearly all (>99%) of an airborne virus in an occupied work environment, showing that the technology can work as well in a real-life scenario as in the laboratory.

“The results show that far-UVC is highly effective at reducing airborne pathogens in an ordinary occupied room, and so it’s practical to use far-UVC light in indoor areas where people are going about their business,"

“If this virus had been a disease-causing virus, the far-UVC light would have provided far more protection against airborne-disease transmission than any ventilation system,”
