A disposable breathing mask (1) comprising side walls (4, 5) and bottom walls (6, 7) made of multilayer filter material. The mask is attached to a user's head (2) by means of a strap (3) attached to attachment areas (25, 26). Joining the attachment points (25, 26) is a rib (27) which extends over the user's nose. The attachment points (25, 26) and rib (27) together form an exo-skeleton which maintains the positional stability of the strap mounting areas during donning of the mask. Arms (31, 32) extend laterally away from the rib (27) and are arranged such as to apply mild pressure to the side walls (4, 5) in the region of the user's nose so as to ensure contact between the filter material and the user's nose.
