UVC disinfection

We need to reduce pathogens in indoor spaces

CounterAct fixtures contain Ushio Inc.’s Care222® lamps that emit far-UVC light that has been shown in the lab to inactivate more than 99% of pathogens, including the SARS-CoV-2 coronavirus that causes COVID-19. The far-UVC 222nm light the lamps emit destroys the DNA and RNA of bacteria and viruses, inactivating them so they are unable to reproduce.

Not all UVC light is created equal

Far-UVC is a type of UV light that has long been used to disinfect spaces. But the longer wavelength (254nm) UVC light that’s traditionally used for disinfection presents a health risk to our eyes and skin, so can’t be used when people are present.

What’s new is the discovery and application of far-UVC 222nm light, a sweet spot on the UV spectrum, to effectively inactivate pathogens with people present without the need for protective gear. It’s technology that’s safer for use in occupied indoor spaces that allows for automated, continual pathogen-reduction.

But don’t just take our word for it, download our far-UVC light white paper and learn about the science and the studies behind the Care222 technology in our CounterAct products.

Christie CounterAct products with patented Care222 technology

Let’s return to the places we love

Christie CounterAct commercial UV disinfection fixtures contain patented Care222® technology that emits filtered far-UVC 222nm light, designed to neutralize pathogens with people present while meeting established safety guidelines. Care222 is also the world’s first UVC technology with a proprietary optical filter that blocks potentially harmful longer (>230nm) UVC wavelengths from being emitted.

Now, and for the future

Urbanization, worldwide population growth, and global travel contribute to diverse contact among people, livestock, and wildlife, increasing the frequency and transmission of new pathogens that may harm us. We need safe and effective disinfection technology that reduces pathogens now, and for the future.
