A customized mask that protects you against unknown substances in the air. This mask is made from accessible materials (such as EVA foams and air filtration filers) and utilizes digital fabrication techniques (including 3D printer, laser cutter, and vacuum former). The shield-like design illustrates protections. One-way air-intake valves and air filtration filers provides basic protections which reduce exposures in the air. The digital fabrication techniques allow users to customize and adjust the shapes as well as designs of the mask; the mask can stay on the face comfortably for a long time in their preferred styles.
