Designed by re:3D, this improved PPE Face Mask uses flexible TPU and an accordioned edge to fit to the face and provide a tight seal. The Flexfit Face Mask accepts a 2” x 2” piece of filter material to reduce the amount of filter material needed to provide protection. A PETG part holds the filter material in place. The mask accepts standard 0.25” elastic to strap to the face. This design was submitted to an America Makes Maker Challenge for PPE design for the COVID response effort.

 

This NIH design entry includes both a large and small version of the face mask to accommodate different faces. Both versions are compatible with the same size filter material and elastic straps, and both use the same PETG part to hold the filter material.
