Abstract

A respirator includes a mask having a body extending between a front edge and a rear edge, and a face seal extending inward from the body. The face seal has a first wall extending from the body and a second wall intersecting with the first wall at a sealing land. The sealing land is configured to contact a user's face to form a continuous circumferential seal. The face seal is folded over such that the first wall and the second wall both extend away from the sealing land in a common direction. Optionally, the face seal may be U-shaped.
