  • a filtering mask typically contains filtering material, for example material preventing or reducing entry of one or more potentially hazardous vapors.
  • a mask may seal with a user's face on at least a portion of the perimeter of the mask. And often times, the seal about the nose region may be particularly important, since the typical contours of a human face may result in potential gap formation in this region of the mask.
