ABSTRACT:
An improved filter element for fluid circulating system having unpressurized reservoirs and primarily adapted for removing algae and other fine contaminants from swimming pool water comprising pleated filtration medium arranged in a cylindrical configuration having an open central area, a cap bonded to one end of the filtration medium to close the open central area, an adapter bonded to the opposite end of the filtration medium for connection to a flow source to direct the flow of water into the open central area for passage through the filtration medium in a direction from inside to outside and an outer support member disposed on the exterior of the filtration medium and closed at one end and secured at the other end to the adaptor to restrain the filtration medium. The outer support comprises a multiplicity of braided criss-cross strands of metallic or non-metallic material defining a tubular structure which is adapted to permit limited radial expansion of the filtration medium to expose the full area thereof to the flow.
