For over 140 years, scientists have discovered that ultraviolet light can disinfect drinking water, wastewater, air, pharmaceuticals, food, and surfaces. UV-C light is incredibly effective in deactivating pathogens, including bacteria and viruses.
UV-C inactivation depends on lamp power, distance and exposure time and follows the inverse-square law. In healthcare, UV-C can reach the high equivalent air-change rates that ECDC recommends, entirely chemical- and ozone-free. Correct dosing and coverage are what turn UV-C into a validated clinical tool.
