How exactly does the CASPR unit work? 

CASPR’s Natural Catalytic Conversion utilizes a multi-wavelength ultraviolet light to illuminate a target surface. The target surface is a honeycomb matrix treated with a proprietary photocatalytic coating. Together, the technology converts H2O and O2 in the air into safe but effective levels of Hydroxyl Radicals (OH-), Oxygen ions (O2-) and Hydrogen Peroxide (H2O2) dispersed throughout the elevator interior, coating all surfaces with highly effective oxidizing molecules that work to reduce the bioburdens of clinically relevant pathogens 24/7.. The CASPR technology produces no ozone.
