Zusammenfassung:	A respiratory mask includes a body configured to cover a nose and a mouth of a user. The body includes a face seal configured to at least partially seal the body to a face of the user. The face seal includes a standard reflex seal that is configured to engage in physical contact with the face to form a first segment of a seal between the body and the face. The face seal also includes a reverse reflex seal that is configured to engage in physical contact with the face to form a second segment of a seal between the body and the face. This configuration allows the mask body to float in place with respect to the face seal and preserves the seal between the mask and the face, even when the user is talking or moving his or her face.
