The application of the HPPORS is to provide a compact, high performance air purification device for spacecraft environmental control and life support system (ECLSS) for extending NASA's mission beyond low earth orbit to include long-duration space habitation, Lunar, and Mars colonization missions. This is accomplished by the innovative HPPORS device which combines energy efficient visible LED-based source illumination, high photon utilization, visible light activated photocatalysts, high reactor surface-to volume, and low pressure drop. This technology applies to any system where removal of toxic industrial chemicals and pathogens are present in air, and where robust operation with minimal supply logistics is required. Other government agencies such as the Department of Defense would benefit from this technology in similar applications such as collective protection of the warfighter from chemical-biological weapons attack. The technology would have numerous commercial and private customers in sectors including homes, schools, commercial offices, hospitals, and public transportation. The potential public benefits of an effective air purification system include fewer lost school and workdays due to sick-building syndrome and communicable illness.
