    摘要： 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 identify where the nose clip may be bent to prepare it for donning by the wearer.

    摘要： A flat-fold filtering face piece respirator 10 that comprises a mask body 12 that has a transversely-extending line of demarcation 22 and a longitudinal axis 34. First and second weld patterns 32a, 32b are disposed above and not traversing the line of demarcation on each side of the longitudinal axis 34, respectively. Third and fourth weld patterns 32c, 32d are disposed below and not crossing the line of demarcation 22 on each side of the longitudinal axis 34, respectively. Each of the first, second, third, and fourth weld patterns 32a-32d is a two-dimensional enclosed pattern. This combined weld patterns can provide a mask body that exhibits crush resistance without the need for additional or heavier layers, which may cause higher pressure drops across the filtering structure.
