Abstract: A filter is disclosed that includes a cylindrical filter element having a longitudinal axis, an outer periphery, an inner periphery, and a plurality of longitudinal pleats arranged in a spiral configuration in close proximity to one another. Each of the pleats has a pair of legs, and the legs of each pleat are joined to one another at a root. The roots of adjacent pleats are radially spaced from one another about the inner periphery of the filter element.

Abstract: A filter assembly is formed of an impervious elongated tubular housing and an elongated filter member positioned within the housing. In a first embodiment a barrier is interposed between a filter member first surface and the housing internal tubular surface adjacent the housing inlet end and another barrier is interposed between the filter member second surface and the housing internal tubular surface adjacent the housing outlet end. In a second embodiment, the filter member is formed of a pleated sheet, the pleats being folded at their ends, and the pleated sheet is formed into a frusto-conical shape with the conical base secured to the tubular housing interior surface. Air flowing into the housing inlet end passes through the filter member before exiting at the outlet end.

Abstract: The invention features a filtration segment having a top seal, a bottom seal and a primary filter core and the method of filtering with the design of the filtration segment. The primary filter core is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. The filtration segment also includes one or more interior filters surrounding the primary filter core. Each interior filter includes a filter material surrounding a secondary core which is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. Each filter may optionally include a retaining medium enclosing the filter material. The filtration segment has one or more layers of an exterior filter media which operatively surround the interior filters and are operatively coupled to the top seal and the bottom seal.
