A horizontal flat-fold, filtering face-piece respirator 10 that includes a harness 14 and a mask body 12 that has a front surface, a first perimeter 24a, and a longitudinal axis 34. A nose clip 30 is secured to the mask body 12 centrally and adjacent to the first perimeter 24a of the mask body 12. An indicia 32 that is visible on the front surface of the mask body 12 in a vicinity of the nose clip 30 is provided to highlight a longitudinal axis of symmetry of the nose clip. The use of such an indicia, visible from the mask body front surface, enables a user to readily indentify where the nose clip may be bent to prepare it for donning by the wearer. |
