Abstract
The present disclosure relates to an improved sealing element for a facemask. The sealing element includes three primary faces: a facemask attachment face; a skin contact face; and a third face. The skin contact face is the longest of the three primary faces when the sealing element is viewed in cross-section. The third face extends from a plane defined by an attachment surface of a corresponding facemask. When the sealing element is viewed in cross-section, the third face has a length that is less than 90% of a length of the skin contact face. Moreover, an entirety of the third face is configured to form a portion of the corresponding facemask's chamber when the facemask is worn by a user.
