About
Summary Inventors at Georgia Tech and Emory have developed a modified face mask with an engineered ventilation layer over the upper portion of the face mask to ventilate air exhaled by the wearer with no added breathing resistance. The top and bottom edges of the ventilation outer layer may be easily bonded to mask by conventional heat sealing, sonic or other bonding techniques. Opposite side edges of the ventilation layer are not bonded with face mask, thereby allowing free movement of exhaled air through two side openings. The new face mask provides economical fog-free use with inexpensive standard face shields.
