A ‘new’ kind of ultraviolet light kills almost all microbes in a room and could help avoid another lethal pandemic, a new study shows.
Researchers say ‘far-UVC’ light emitted from ceiling lamps can kill bacteria, fungi and viruses, including coronavirus, without causing damage to the human skin.
In experiments, far-UVC took less than five minutes to reduce the level of indoor airborne bacteria by more than 98 per cent.
Even as microbes continued to be sprayed into the room, their level remained very low as long as the far-UVC lights were on.
