ABSTRACT:
Filter assemblies are disclosed that include a pleated web in which the pleats are connected to each other to provide support for the filter media during use. The interconnected pleats preferably form an array of openings facing the upstream side of the filter assembly when subjected to fluid pressure during use. In addition, the preferred filter media also includes an array of pockets located behind each of the points at which the pleats are connected. By connecting the pleats to form arrays of openings and pockets during use, the filter assemblies provide a structure that deforms in a predetermined, acceptable manner without the need for external support structure to support the pleats.
