What is Care222?
The Care222 technology is a brand new kind of ultraviolet (UV) light technology that can inactivate viruses—including the coronavirus—in occupied spaces.
Care222 is a new and one-of-a-kind disinfecting light technology that inactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers, but can be used while people are present. Care222 is not a stand-alone disinfecting system, but is a key component in the very latest UV light disinfecting systems available.

Why Care222?
Learn why Fortune Magazine called Care222 Far UV-C light a technology that can literally "change the world."
Conventional disinfecting systems equipped with standard UV lights cannot be used when people are present. Care222 developed something called filtered Far UV-C light, which can be used to continuously disinfect the air and surfaces in a space while people are present. Given the pressing need now to control viruses and bacteria, Care222 is the right technology at the right time.

Care222 at a Glance
The Care222 technology is effective, and beneficial
Like a lot of the technology we are around every day, having a basic understanding of how that technology works often helps us feel better about its use. The most important thing to know is that when a disinfecting system powered by the Care222 technology is being used in any public building, it has been put there to bring you and everyone else, a sense of comfort.

The Science Behind Care222
This is where we get to geek out a bit over our science.
Now you don’t have to love science like we do to benefit from Care222 systems, but we do want to share some of the science behind our technology. The best way to do this is to talk about UV light, wavelengths, and the filter that makes our light so remarkable.

What 222 Means and Why It's Important
The numbers in our name represent 222 nanometers (nm)—the wavelength at which Care222's Far UV-C emits its light on the UV spectral region.
Conventional germicidal UV light, the kind that is used to disinfect unoccupied spaces like hospital operating rooms, emits at 254nm, and is unsafe for exposure to people. This is the dilemma and the problem that researchers at the Columbia University Irving Medical Center and leading universities around the world were able to help us solve.

Inactivating the Virus That Causes COVID-19
Research has demonstrated that irradiation with filtered 222nm Far UV-C light effectively inactivates SARS-CoV-2, the virus that causes COVID-19.
Our important breakthrough came with the development of our filter. The Care222 filtered Far UV-C excimer lamp module is equipped with our proprietary optical filter technology that ensures a narrowband 222nm emission. Our filtered 222nm Far UV-C light can be used with people present, while traditional 254nm UV-C light or unfiltered Far UV-C sources cannot.

Frequently Asked Questions
The Care222 technology is a new disinfecting Far UV-C light source that inactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers but is not harmful to either humans or animals.
Other available disinfection methods like chemical disinfectants or conventional UV disinfection are only used intermittently, and usually when people are not around. The Care222 technology is working all the time, including when people are present, allowing continual disinfection of the air and environmental surfaces.
Yes. Care222modules use an excimer lamp in combination with a special optical band pass filter that blocks the ultraviolet wavelengths that could have a harmful effect on people. Care222 is the only Far UV-C product in the world with this key technology.
