Complex Geometries for Extended Wear Respirators Towards Regenerable Particulate Matter Protection
SBIR Opportunity Analysis
The Department of Defense, through CBD, is seeking SBIR solutions under topic CBD254-005 to develop a rugged, 3D-printable, PFAS-free particulate filtration impactor system for extended-wear respirators in military environments. The work calls for a regenerable filter or module that can attach to existing masks and respirators, trap inhaled aerosols, and be manufactured at the point of need with minimal size, weight, and power requirements. Phase I emphasizes swatch-level demonstration against PM10 and PM2.5 with over 95% reduction, low breathing resistance, and resistance to clogging for 12 hours, while Phase II expands to regeneration testing over three cycles, higher-flow testing, and prototype integration into a commercial respirator or mask. The submission deadline is May 13, 2026, at 4:00 p.m. ET.
