ABSTRACT:
Disclosed is a novel light weight inexpensive full face mask in which the air filtration function is carried out by an air filtration shell which has at least a portion of its surface made of a porous filtration material. The air filtration shell also acts as a breathing chamber. Also disclosed is a lower cost yet an effective method for providing a cooler breathing chamber and minimizing the volume of re-inhaled exhaled-air in any full face mask.
