Abstract: A breathing half mask, which can be brought by a folding operation from a storage state into a use state. A mouth area is arranged between a nose area (11) with a nose sealing line (41) and a chin area (12) with a chin sealing line (42). A first connection section (14.1, 14.2) connects the nose area (11) and/or the chin area (12) to the mouth area. A second connection section (15.1, 15.2) connects the nose area (11) and/or the chin area (12) to another mask area (10) in order to limit the nose sealing line (41) and/or the chin sealing line (42). The second connection section (15.1, 15.2) extends a distance from an edge of the nose area (11) and/or from an edge of the chin area (12) between the first connection section (14.1, 14.2) and the nose sealing line (41) and/or the chin sealing line (42).
