UVC: What Does The Science Say?

According to data from the International Ultraviolet Association, UV treatment has been around for more than 40 years. As a tried-and-tested solution, UV disinfection is prevalent in hospitals, medical or healthcare centers, laboratories, food processing, wastewater facilities, HVAC system management and more.

UVC Light: Earth's Natural Bioweapon

UVC light contains several unique properties and characteristics, which can be used to disinfect up to 99.9% of viruses, bacteria, mold, spores and other harmful microbes. According to experts from University of British Columbia, University of Alberta, University of Colorado-Boulder and Trojan Technologies, UVC light is capable of killing tuberculosis, e.coli, methicillin-resistant S. aureus (MRSA) and more. Initially, this sanitation method relied on the UVC spectrum, i.e. UVC rays within the range of 200 nm to 280 nm (traditionally optimized at 254 nm), to deactivate the cellular ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), as well as the reproductive capabilities of microorganisms. Although highly effective in eliminating microbes on surfaces and in the air, [most of] the UVC band is dangerous to humans. Extended exposure to this UVC wavelength, typically using fluorescent UV lamps, can cause mild to severe sunburns and temporary to permanent vision loss without proper safety gear. Since the late 1800s it’s understood that artificially produced UV can be harnessed to kill microorganisms, and consequently has become a staple method of sterilization. It’s also fundamental in the process of purifying drinking water because many parasites are resistant to chemical disinfectants (such as chlorine), but UVC can eliminate them. UVC is a kind of biologically active radiation, and breaks up the RND and DNA of the pathogens that harm us – rendering them unable to infect. Next Level UVC LED Technology: The Future of UV “The disinfection systems based on LED bulbs, ...can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room." "We killed the viruses using cheaper and more readily available LED bulbs, which consume little energy and do not contain mercury like regular bulbs. Our research has commercial and societal implications, given the possibility of using such LED bulbs in all areas of our lives, safely and quickly.” - Professor Hadas Mamane, Tel Aviv University
