Abstract: One or more embodiments of a respirator and a method of making the respirator are disclosed. The respirator can include a harness (60) including first and second straps (62, 64); a mask body (12) including right and left portions (16, 18) on each side of a centerline (24), where the right and left portions (16, 18) are bounded by a perimeter (24) of the mask body (12); a right tab (30) that extends from a right side perimeter segment (26) of the perimeter (24) of the mask body (12) adjacent the right portion (16); and a left tab (40) that extends from a left side perimeter segment (28) of the perimeter of the mask body (12) adjacent the left portion (18). The first strap (62) of the harness (60) is attached to the right and left tabs (30, 40) at first right and left attachment locations (50, 52), and the second strap (64) is attached to the right and left tabs (30, 40) at second right and left attachment locations (54, 56).
