This was pretty much guaranteed. There were multiple studies showing that UVC (not Far-UVC) quickly and effectively killed coronavirus. It was basically just crossing the t’s and sorting the i’s to test Far-UVC light that it did the same thing. But based on everything else it was obvious it would.
I’m hopeful we can see a lot of low cost Far-UVC appliances over the next year that safely killed coronavirus in indoor places so that we can start living a normal life before vaccines become widespread.
