A respirator (10) includes a mask (12) having a body (32) extending between a front edge (34) and a rear edge, and a face seal (30) extending inward from the body (32). The face seal (30) has a first wall (50) extending from the body and a second wall (52) intersecting with the first wall at a sealing land (54). The sealing land(54) is configured to contact a user's face to form a continuous circumferential seal. The face seal (30) is folded over such that the first wall (50) and the second wall (52) both extend away from the sealing land (54) in a common direction. Optionally, the face seal may be U-shaped.

Le joint facial (30) a une première paroi (50) s'étendant depuis le corps et une seconde paroi (52) croisant la première paroi au niveau d'une plage d'étanchéification (54). La plage d'étanchéification (54) est configurée pour venir en contact avec le visage de l'utilisateur pour former un joint étanche circonférentiel continu. Le joint facial (30) est replié de telle sorte que la première paroi (50) et la seconde paroi (52) s'étendent toutes les deux loin de la plage d'étanchéification (54) dans une direction commune.
