Using the Power of Light: Preventing the Airborne Spread of Coronavirus and Influenza Virus—DAVID J. BRENNER(Center for Radiological Research)
Over the past six years, we have been working on a very exciting new approach to killing drug-resistant bacteria – superbugs- , as well as airborne viruses such as influenza, using a unique type of ultra-violet light. We have always known that ultraviolet light can efficiently kill all microbes, but conventional germicidal ultraviolet light is hazardous to our health, causing skin cancer and cataracts. We have identified a particular wavelength of UV light that has the best of both worlds – it’s safe and it kills microbes – including superbugs.
In brief, it is pure physics – 222 nm light is safe for us because it cannot even penetrate through the dead-cell layer on the surface of our skin or the tear layer on the surface of our eyes – but because bacteria and viruses are physically very small, 222 nm light does have enough penetration to efficiently kill them.

Currently, the most effective and safest way to fight against COVID-19 is far uvc 222nm technology, but experts warned that some of the products are not certified.
A key advantage of the UV-based approach is that UV light is likely to be effective against all airborne microorganisms, in marked contrast to vaccination methods. For example, while the inactivation efficiency of UV light will almost certainly vary as different strains of influenza virus emerge, they are unlikely to be significant. Similarly, as multidrug-resistant variants of bacteria emerge, their UV inactivation capacity is unlikely to vary greatly.
Care222 is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers.
It can be installed in a high location, such as on the ceiling, to irradiate its entire surroundings. This makes it possible to deactivate or eliminate a wide variety of viruses and bacteria both in the air and on environmental surfaces.
Care222 uses an excimer lamp (a mercury-free UV excimer light source produced by Ushio especially for outputting monochromatic ultraviolet with a primary wavelength of 222 nm) in combination with a special optical bandpass filter (200 to 230 nm) which passes only ultraviolet wavelengths that have no harmful effect on people.
Ushio holds exclusive rights to utilization of the key technology, which was patented by Columbia University (New York, NY) in 2012.
Only 222 nm, which is filtered by a special optical bandpass filter for the rest of the harmful wavelengths, is safe for humans.
The use of Care222 in public places is a safe and effective way to limit the spread and transmission of air-mediated microbial diseases, such as schools, hospitals, stadiums, sports grounds and offices, and this approach may help to limit seasonal infections, the spread of tuberculosis and major epidemics. It’s inevitable far uvc will become part of the new World people are more aware and want to be protected from viruses.

• Does not cause sunburn, skin cancer or cataracts
Ultraviolet rays with a wavelength of 222 nm are absorbed by the cornea of the stratum corneum of dead cells, so they do not cause damage such as sunburn, skin cancer, and cataracts.
• Virus suppression / sterilization
Ultraviolet rays with a wavelength of 222 nm destroy the DNA / RNA structure of viruses and cells, and suppress and sterilize them.
• Continuously disinfecting in occupied space but not harmful to skin and eyes of people, which could be used in dental offices, medical rooms, high-end offices, elevators, hospitals, class rooms, etc.
