Could Far-UV Light Provide Widespread Disinfection of Airborne Viruses?

A short-wavelength ultraviolet light technology, beyond the decades-old mercury lamp, may be the most promising breed of UV yet studied for killing airborne coronavirus and other viruses and bacteria. Two studies—one now under peer review, and one reporting preliminary results from an ongoing experiment—bolster the case that this UV is safe for human eyes and skin. https://spectrum.ieee.org/tech-talk/biomedical/devices/ultraviolet-revolution-could-faruv-light-provide-widespread-safe-disinfection-of-airborne-viruses
