摘要

The mask has a flexible plastic frame (1), which fits the wearer's face and has a net (6) across it to hold the wadding filter (7). A bar crosses the frame from side to side, to support the mouthpiece (4), which is held between the teeth. a transparent eyeshield (2) may be fitted above the mask. The mouthpiece may be shaped in various ways to fit the mouth, and to allow the mask to be pulled closer against the face by biting harder. In another version, the mask can be taken apart for the filter material to be renewed.
