Complex Geometries for Extended Wear Respirators Towards Regenerable Particulate Matter Protection
SBIR Opportunity Analysis
The Department of Defense, through CBD, is seeking an SBIR solution to develop a rugged, 3D-printable, PFAS-free particulate filtration impactor system for extended-wear respirators in military environments. The work focuses on a regenerable filter or module that can attach to existing masks and respirators, trap particulate matter during inhalation, and be manufactured at the point of need. The effort emphasizes low breathing resistance, resistance to clogging during aerobic activity, compatibility with current respirator designs, and performance against PM10 and PM2.5 under both liquid and solid aerosol testing conditions. Phase I calls for swatch-level demonstration with more than 95% reduction in solid and oil particulates for 12 hours and delivery of three 5.3-inch swatches, and the application deadline is May 13, 2026 at 4:00 PM ET.
