During the course of this pandemic, we have learned that exhaled breath from an infected person is the most significant way in which the virus, SARS-CoV-2, is shed, accumulates in the air and is transmitted to others. Shared air explains cluster infections or outbreaks and the speedy progression of the pandemic. While enhanced ventilation minimizes the risk of infection by airborne SARS-CoV-2 viruses, de-densifying contaminants in the air and on surfaces is also a critical part of risk reduction.

CASPR’s hospital-grade Medik product line was engineered for deployment in healthcare environments, placed in the ventilation ducts of preexisting air management or HVAC systems.

Recognizing the need for more flexibility and accessibility of this technology, a cost-effective stand-alone version of this technology, the CASPR Compact was developed. It continuously produces and dispenses ambient air enriched by gaseous oxidizing molecules that decompose airborne pathogens from aerosols and droplets of all sizes in the air and on surfaces.

CASPR Compact is not a filtration device, does not dispense disinfection fluids, and is not intended to decompose pathogens in the unit or device. It is not designed to replace existing disinfection and personal protection measures and protocols.

Rather, it is an additional risk reduction measure to minimize transmission of respiratory pathogens and other particulates.

CASPR’s hospital-grade technology is safe for use in occupied spaces and causes no damage to equipment in the environment.

How it Works

Air passes through a honeycomb matrix coated with titanium dioxide (TiO2) and other reactive metals and is exposed to multiple wavelengths of ultraviolet light. This process, called photocatalytic oxidation (PCO), produces oxidizing molecules including hydrogen peroxide (HP), H2O2, gas. Even at low concentrations HP in its aqueous form is a powerful disinfectant. Trace amounts of gaseous HP and other oxidizing molecules are very efficient in decomposing pathogens.  These oxidizing molecules are effective in reducing harmful viruses and bacteria in the air and on surfaces. CASPR’s hospital-grade systems have been proven to reduce pathogens by more than 99.96% in multiple clinical and laboratory tests.

The PCO technology was originally developed by National Aeronautics and Space Administration (NASA) for purifying ambient air in the Space Station. CASPR used NASA’s technology as a starting point to develop their own, proprietary photocatalytic process.

For optimal performance and circulation of oxidizing molecules, CASPR Compact should be placed at countertop level, closer to an air supply vent and away from air returns. Never on the floor. Unobstructed airflow is needed on both the front and the back. Allow at least six inches from the back of the unit to the wall. On a shallow shelf, the unit should be turned sideways to accommodate airflow.
