What is Care222™?

  • Waiting room
  • Toilet
  • Food processing
  • Public/transportation

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. Ushio provides these lamps in modules combined with optimized power supplies.

One of Care222™’s greatest features is that it can be used all the time. Unlike conventional ultraviolet light sources, Care222™ can be used even when people are present, allowing continuous disinfection of the air and environmental surfaces.

* About Care222™
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.

* The Care222™ standard character mark and stylized logo mark are trademarks of Ushio America, Inc., or its affiliates registered in the United States, European Union, and the United Kingdom and used in many jurisdictions worldwide.
