The ABC Mask

Atlanta Beats Covid (ABC) has been developing a reusable and sanitizable plastic/rubber mask to serve as a temporary stop-gap for disposable N95s under the condition that they are not NIOSH-approved, although they can fit a wide range of proven 95% PFE filter media (particle filtration efficiency). This design aims to fit a wide variety of face geometries through a conformal silicone rubber seal housed inside a plastic shell. Due to the need for a seal with complex geometry and high-volume manufacturing, this design is primarily intended for molding and casting, although the plastic shells can be 3D printed. Your manufacturing efforts will consist of making six components; two silicone rubber parts (a seal for the face and a gasket for the filter medium), two plastic parts (inner and outer shell), and two elastic management parts. You will also need to purchase elastic and filter material, which must be cut to shape.
