Abstract

A filtration medium including a polymeric netting of polymeric ribbons and polymeric strands. Each of the polymeric ribbons and strands has a length and width, with the length being the longest dimension and the width being the shortest dimension. The polymeric ribbons have a height-to-width aspect ratio of at least three to one or five to one a major surface that is intermittently bonded to a polymeric strand, and a height typically greater than the height of the one polymeric strand. A filter including the filtration medium and a method useful for making the polymeric netting are also disclosed.
