Feel protected. Feel normal.

UVC disinfection to fight harmful pathogens can give us greater peace of mind

Discontinued UVC disinfection

The technology we need, now and for the future

The world is changing. We want to reconnect with family, friends, co-workers, and community. We want the places we gather to feel… normal. We need effective disinfection technology that inactivates harmful pathogens and adds a layer of defense in indoor spaces. Is UVC disinfection the solution?

Not all UVC light is created equal - and some is better together

Traditional UVC light is proven technology — since scientists in the late 1800s first started investigating the power of sunlight to prevent the spread of airborne infections to today where it’s used in commercial disinfection systems. Care222® filtered far-UVC light technology, with its sweet spot on the UV spectrum, can safely and continuously inactivate airborne and surface pathogens when people are present because of a proprietary optical filter that removes longer, harmful wavelengths.

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.

What if we used both types of light—Ushio's filtered Care222 far-UVC light and upper room UVC-LED — in a way that can run safely and continually around people for enhanced disinfection?

CounterAct has you covered

The first-ever technology that uses both far-UVC and traditional UVC light, Christie CounterAct UR10 ceiling-mounted fixtures offer dual protection. Care222 light shines downward to inactivate pathogens on surfaces, and UVC-LED kills airborne pathogens as air circulates across the ceiling. The result is enhanced, continual disinfection of both air and surfaces that makes us feel protected, feel normal when we gather in indoor spaces.

And because CounterAct UR10 fixtures include visible light, you can simply replace existing commercial lighting anywhere people gather — from corporate offices, workplaces, boardrooms, and lobbies, to retail shopping centers, waiting rooms, and transit hubs.

All references to “disinfect”, “disinfecting”, and “disinfection” refer generally to the reduction of pathogenic bioburden and are not intended to refer to any specific definition as may be used by any governmental or regulatory authority, including the US Food and Drug Administration and the US Environmental Protection Agency. Christie CounterAct products with patented Care222 technology are not medical devices and are not to be used as or for medical devices. The pathogen-reducing efficacy of Christie CounterAct products and their use in occupied spaces is dependent on many site-specific factors as well as proper installation and operation within specifications and in accordance with the American Conference of Governmental Institutional Hygienists (ACGIH) guidelines. Professional installation is recommended for Christie CounterAct products.
