Abstract: Passing a fluid though a single filter module effectively removes at least two different types of impurities from the fluid. The fluid is directed through at least two different types of filtering media within the single module. The at least two different types of filtering media are separated from one another, within the single module, by a porous containment layer of the module; and, one of the at least two different type of filtering media forms a core of the module, which is surrounded by the porous containment layer.

Abstract: A portable housing contains and forms a space around a filter element to form a portable filter assembly that can provide filtered hydration from a portable fluid reservoir. The housing includes an inlet port, which is in fluid communication with the space, and an outlet port, which is in fluid communication with a core of the filter element, wherein an external fitting of the housing, which is configured for coupling to a suction source outside the housing, surrounds the outlet port. The suction force draws fluid into the space, from the reservoir, which may be coupled to the inlet port by a tubular member, and then through the filter element and out the outlet port. An attachment feature may extend from an outer surface of the housing so that a strap-like member may engage therewith.

Abstract: A filter module that is attached to a combination manifold and valve system may be replaced by simultaneously shutting off an inlet opening and an outlet opening of the system while releasing a securing member of the system from a securing position. The simultaneous shutting off and releasing are accomplished by rotating a rotatable structural member of the system from a first position to a second position.

Abstract: Modular assemblies of filtering systems provide options for installing any number of filter elements in parallel arrangement. The assemblies may be formed by coupling together and placing at least two modular manifold parts on a mounting bracket, and engaging a mounting ring, which is slideably engaged about a sidewall that surrounds each filter element, with a quick connect member of the mounting bracket. The at least two modular manifold parts may be selected from a modular manifold kit that includes either a plurality of a first type of part or at least one first type of part and at least one second type of part. The first type of part includes first and second channel portions to support inflow and outflow for each filter element and the second type of part is configured to serve as both an end cap and an adapter for the first type of part.

Abstract: A combination manifold and single lever cantered element system to which a filter module removably attaches. A ¼ rotation of the single lever mediates simultaneous operation of both valving and filter module release, and facilitates changing removably attachable filter modules without the need for tools.
