Does UV Light Kill Viruses?

Ultraviolet (UV) light is light emitted at wavelengths shorter than visible light in the range of 10 to 400 nanometer (nm) and is either in the UVA, UVB or UVC range.  UV light at precisely 254 nm is UVC light in the exact wavelength optimal for effective sterilization.  UVC wavelengths at 254 nm are proven to kill bacteria and viruses. 

UVC germicidal lamps designed to emit light at 254 nm are used to destroy harmful pathogens with a high rate of efficacy, killing 99.99% of harmful microorganisms.  Germicidal UVC lamps are used in many surface, water and air purification systems worldwide.  UV sterilization is currently used in many environments such as medical facilities, research labs, hospitals, nursing homes and pharmaceuticals. 

UV light is also used in a myriad of water sterilization applications including wastewater treatment, ballast water treatment systems, fish hatcheries, pools, spas, drinking water applications and more.  UV light kills bacteria that chlorine does not, is safe and effective.  UV light in air purification systems will eliminate the transmission of harmful pathogens through the air and ozone lamps will even remove foul odors from the air.

UV Lamps Protecting People from Coast to Coast

Medical facilities worldwide are increasing the use of UV light to sterilize hospital rooms as UV lamp manufacturers ramp up production.  UVC irradiation has been tested in New York on buses and subway cars.  UVC lamps used to sterilize buses in Shanghai are proving to be effective while reducing sterilization time from 40 minutes to about 5 minutes, with no labor expenses. 

A UV sterilization system that can be utilized on aircraft and pushed through a plane like a refreshment cart is produced on the west coast in Los Angeles.  Airplane giant Boeing is working on developing a self-cleaning system for bathrooms on planes that kills germs with a burst of UV light. 

UV light radiation technology is being utilized around the globe as Japan and the U.S. work to make places safer for residents.  Moving about public places, going to school or riding the subway may soon be safer with UV light technology despite the pandemic threat.
