    Abstract: A filter formed essentially from a staple fiber is provided. A nonwoven staple fiber is compressed in to a mat or sheet of selected porosity. The mat or sheet does not include a binder or bicomponent fibers. The staple fibers may be heat treated. The sheet is formed into a selected geometric shape and the staple fibers are thermally fused to bind the staple fibers into a porous filter element. The preferred shape is a helically wound tube or plural sheets, each sheet being self-overlapped and compressed to overlap another sheet. Each sheet is preferably heated and compressed individually and the sheets may be selected to have different porosities and densities.

    Abstract: There is disclosed a liquid filter system that includes a liquid filter apparatus configured to self-clean without removal of the filter apparatus from the filter system. The filter apparatus uses both a filter media for filtering solids as well as a spin motion imparted to fluid being filtered so that centrifugal force can remove solids from the liquid being filtered. The liquid filter system also includes a gas pulse nozzle in fluid communication with the liquid filter apparatus and is configured to flow gas into the filter media to expel water and debris trapped in the filter media without removing the filter media from the filter system.
