One or more embodiments of a respirator that includes a polymeric netting is disclosed. The respirator can include a mask body including a perimeter, a harness attached to the mask body, and a face seal disposed adjacent at least a portion of the perimeter of the mask body. In one or more embodiments, the face seal includes a polymeric netting including polymeric ribbons and polymeric strands, where each of the polymeric ribbons and strands having a length, width, and height, where the length is the longest dimension, the width is the shortest dimension, and the height is the dimension transverse to the length and the width. The polymeric ribbons have a height-to-width aspect ratio of at least 5 to 1, a major surface that is intermittently bonded to only one polymeric strand, and a height that is at least two times greater than a height of the one polymeric strand.
