Abstract: A maintenance-free respirator 10 that includes a mask harness and a mask body 11. The mask body 11 has at least one layer of filter media 56 and has a perimeter 32 that includes an upper segment 34. The upper segment 34 includes first and second concave segments 36, 38 that are located, respectively, on first and second sides of a central plane 40, when viewing the mask body from a top view. A maintenance-free respirator 10 of this configuration is comfortable to wear and can provide a snug fit to a wearer's face, particularly beneath each of the wearer's eyes, while at the same time having an ability to improve compatibility with various protective eyewear.
