CASPR 1000 In-Duct disinfection technology uses a proprietary Natural Catalytic Converter (NCC) process to naturally extract oxygen and moisture from ambient air and then produce and continuously deliver trace levels of hydrogen peroxide (H2O2) to disinfect indoor spaces. The result is an automated and continuous reduction of air and surface viruses and bacteria. A study showed it to kill 98 percent of SARS-CoV-2 viruses on surfaces within six hours and 99.99 percent within 24 hours.
