In some previous discussions of far-UVC, on LessWrong the idea was to let the far-UVC light be focused on the space above people’s heads so that you clear a lot of viruses in the air while not directly going on people’s skin.
Link? That sounds like “upper room” UVC, which is longer wavelengths (ex: 254nm), not far-UVC (222nm).
