A generally pouch-like conformable face mask especially suitable for surgical use. The face mask includes a generally rectangular body portion formed from a filtration medium and having top and bottom edge portions and a pair of opposed side portions. To provide the face conforming features and a substantially gas-tight seal between the mask and the face of the wearer, an elastically extendable material is located at the periphery of the side and bottom edge portions of the generally rectangular body portion, mask to gather into a pouch or cup-like configuration. This permits the wearer to don the face mask by engaging the pouch-like portion with the chin fitting within the pouch while the body portion covers the mouth and nose of the wearer. |
