In a new study, scientists reveal a new type of ultraviolet light called Far-UVC that could ‘dramatically change’ our fight against airborne pathogens, including the notable COVID-19.

According to ScienceAlert, this new kind of ultraviolet light safely kills airborne pathogens in indoor environments. It even represents a new ‘hands off’ way of suppressing COVID-19 spread, and works far better than other existing control measures that involve significant changes in how society moves – such as wearing masks, abiding by lockdowns, physical distancing, or nationwide vaccination.

Good news is, Far-UVC lighting indoors is simple to install and “could be about as easy as changing a light bulb.” “Far-UVC rapidly reduces the amount of active microbes in the indoor air to almost zero, making indoor air essentially as safe as outdoor air,” biophysicist David Brenner from Columbia University Medical Center said in the university’s page. “Using this technology in locations where people gather together indoors could prevent the next potential pandemic.”

While UVC light has been known to pose potential health hazard to the skin and eyes, a decade-study reported in Scientific Reports resulted in the discovery of the new type of UVC light which would be just as efficient at killing bacteria and viruses, without worrying about the safety hazards from conventional germicidal UVC.

Efficacy in Real Room Environment

Findings show that the device was equally effective in a normal-sized room and reduced up to 98.4% of the pathogen load in a matter of minutes, maintaining an ambient level of 92% reduction at a level in line with International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.

In this case, the researchers used a sealed facility the size of a single-occupancy hospital room where different types of building ventilation and devices can be implemented to test the potential effectiveness of approaches like Far-UVC in a full-scale situation, said environmental microbiologist Louise Fletcher from the University of Leeds in the UK.

Physicist Kenneth Wood from the University of St Andrews in the UK added: “Our trials produced spectacular results, far exceeding what is possible with ventilation alone.”

Although the technology is quite promising so far, scientists acknowledge the possible side effects and difficulties to overcome of using Far-UVC in the real world, such as ensuring that the installation meets the correct level of radiation exposure, “being both effective but also within safe, set limits.”

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.
