CounterAct overview
CounterAct is a commercial UV disinfection fixture containing Ushio Inc.’s patented Care222
®
lamps
that emit far-UVC 222nm light, shown to significantly reduce surface pathogens in occupied and
unoccupied indoor spaces. Care222
®
is based on far-UVC germicidal technology that may also be used
around people and it is the only product with a proprietary filter that prevents longer UVC wavelengths
from being emitted.
The CounterAct devices are installed in the ceiling throughout a space. The light spreads out in a fixed
cone size. Therefore as the ceiling height increases or decreases the output power must be adjusted
up or down respectively. The lamps cannot be dimmed and are only capable of being in the fully on or
off state. Operating modes for CounterAct comply with the UV Threshold Limit Values (TLV) outlined
by the American Conference of Governmental Industrial Hygienists (ACGIH). The TLV is measured as a
time-weighted average for a conventional eight-hour workday.
