There has been some recent buzz about the use of new ultraviolet lights that reportedly kill viruses and bacteria in the air without harming the body. If effective, they could have broad applications in restaurants, food distribution facilities and beyond. But do they work? Columbia University researchers tested the technology, called far-UVC, over the course of eight months and found that it killed the flu virus (their research was published in Scientific Reports) and their previous tests of the technology against MRSA also reportedly killed the bacteria without harming human tissue. Eater reports that Magnolia Bakery, for one, is replacing their recessed lighting with far-UVC light and also having customers pass through a far-UVC light scanner (akin to passing through a metal detector at the airport) upon entering their facilities to kill virus or bacteria they carry with them. Portable UVC lamps are also on the market. While the research is still new and it’s not clear whether the technology is effective against COVID-19, it promises to offer at least some additional protection in conjunction with other sanitation measures as we approach flu season.
