Surface and Air Treatment
UL Listed
Patented short pass filter removes wavelengths that can penetrate the living tissue in skin or beyond the tear layer in the eyes, creating a narrow band 222nm emission
The 222nm wavelength emitted from the filter does not penetrate the living tissue of the skin or tear layer of the eye. The Care222 module can meet exposure guidelines for occupied space established by the American Conference of Governmental Industrial Hygienists (ACGIH®)***
Care222 solutions can target pathogens** both in the air and on surfaces for a dual treatment solution
Care222 modules are UL Certified and are classified as Risk Group Exempt for photobiological risk. The Risk Group Exempt determination made by UL means that there is no photobiological hazard, as described in IEC 62471, for the module when installed and used in accordance with accompanying written instructions.

Proper dosing
Effect on Eyes
The proteins in the tear layer of the cornea of our eyes absorb 222nm far-UVC. When following safety guidelines, the 222nm wavelength does not penetrate deeper than the tear layer to depths associated with cataracts, photokeratitis, and other eye conditions. In contrast, possible acute and chronic damage to eyes may result from the more generally employed 254nm UV wavelength used in many germicidal lamps. In addition, other wavelengths, such as 405nm, that may avoid acute and chronic damage to eyes are not as efficient against viruses and bacteria as the 222nm wavelength.**

When used following safety guidelines, filtered 222nm does not affect living skin cells because it does not penetrate beyond dead skin cells of the stratum corneum.

Care222 filtered 222nm technology utilizes an excimer lamp that employs a specially designed short pass filter to remove longer UV wavelengths, resulting in a narrow band of UV centered at 222nm. Excimer lamps are arc discharge light sources with a special chamber filled with noble gas, completely mercury-free and without electrodes. Acuity Brands luminaires with Care222® far-UVC disinfection* technology employ proprietary integrated controls to modulate pulses of the 222nm far-UVC to provide an appropriate dose that allows operation within the exposure guidelines for occupied space established by the American Conference of Governmental Industrial Hygienists (ACGIH®)***.
Acuity Brands follows the exposure guidelines for occupied space established by the American Conference of Governmental Industrial Hygienists (ACGIH®)*** and adopted by the International Electrotechnical Commission (IEC) in IEC 62471, Photobiological Safety Of Lamps And Lamp Systems in determining the dosing delivered by Care222 products. The level of reduction of pathogens¹ will depend upon the dose delivered, measured in mJ/cm2, which is a measure of radiant energy per unit area. Since the dose is an energy quantity, effectiveness will depend on the amount of irradiation and time of exposure chosen for a particular application at 222nm, relatively small doses over time are needed to inactivate bacteria and viruses and reduce the pathogenic bioburden² on the surface that is in contact with the UV light. Acuity Brands luminaires with Care222® far-UVC disinfection* technology pulse the 222nm at a dose that allows for continual operation in the occupied space while staying within the exposure guidelines for occupied space established by the American Conference of Governmental Industrial Hygienists (ACGIH®)³
