3D-printable PFAS-free respirator impactor for extended military wear

Develop a rugged, 3D-printable, PFAS-free particulate filtration impactor that readily attaches to respirators or masks for extended wear during aerobic activity in military operational environments. The system should be regenerable and provide reliable particulate matter protection in high-dust or high-PM conditions while remaining suitable for field use.
