222nm far-UVC
VS
Coronavirus
Overview
Early stage COVID-19 infection is often both asymptomatic and contagious. By reducing the viral load in airways and hands, we will reduce coronavirus transmission.
Recent studies have shown that far-UVC frequency range of 200-222nm is highly effective against bacteria, but unlike traditional frequencies of 254-279nm, does not pose the same cancer risk.
Modern UVC LED manufacture has also targeted the optimal sterilizing, but dangerous frequency range of 254-279nm, and therefore cannot be safely used on human tissue.
222nm products already exist. We now need to research and develop humanly safe 200-222nm LED emitters to sterilize hands and internal respiratory surfaces. 222nm LED will be a cheap, fast, portable, water and chemical free method of reducing coronavirus transmission.
200-222nm LEDs could also be used to create humanly safe self-sterilizing technology such as fridges, light switches, handles, cars and even deodorants.
