Abstract: Filter modules for use in a water dispenser, carafe, or other gravity- flow water filtration and dispensing unit are self-supporting, rigid and porous, and are adapted in size and shape to substantially fill a generally-cylindrical housing. The filter modules are molded forms of high-porosity compositions, so that they are consistent in performance and "non-dusting" compared to the unpredictable arrangements, positions, and performance of loose activated carbon particles. Filter modules may include activated carbon, zeolitic, resins, metal-scavengers, and/or other water filtration/treatment media granules/powders, for example, bound into a solid profile form by thermoplastic and/or other polymeric binders. Low melt index, or very low melt index, binders are preferred to maximize exposure of the activated carbon surface area. Thin walls of media surround the preferred single core/bore of each module, to preferably form generally D-shaped or triangular modules, wherein multiple modules of the same shape may be attached side-by-side to a housing plate/member, to substantially fill the housing, with the modules close together but spaced to allow water flow between and all around the modules.

Abstract: Multi-core solid profile filter media blocks include multiple sub-blocks, which may be formed by providing a block with multiple interior cavities extending deep into the block, to allow water to flow deep inside the filter block to access the media of the sub-block (in the case wherein the cavities are at the inlet to the block) or that allows water to be collected from each filtration sub-block (in the case wherein the cavities are at the outlet from the block). One or more indentations/spaces/gaps in the exterior surface of the block also may be provided to separate and extend between portions of the sub-blocks, so that substantially all of the filter media of a sub-block is accessible to fluid for filtration. This way, a filter block may include a large amount of media in a small cartridge or package volume, and the filter block may exhibit good flow distribution and low pressure drop. Sub-blocks of the filter block may be integrally formed together into the filter block, or may be directly connected, for example, preferably without any housing or internals clamping or fastening the sub- blocks together.

Abstract: Embodiments of a key system for filters and their connecting heads/holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding "key" and one being a recessed "lock". Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mis-matched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surface of a valve head, or on outer and inner surfaces of connectors that provide a liquid seal between the filter and the head/holder.

Abstract: This invention relates to fluid filters and filter cartridges and connections for the filters/cartridges to piping, valving, brackets, and other holders that cooperate with the filters/cartridges to make them operative in a flowing fluid system. More specifically, this invention relates to a "keyed" system for keying a particular filter cartridge or filter to a particular cooperating filter head member or filter valve head. The keyed system for a filter and its holder comprise a filter (20) and a cooperating holder (10). The filter (20) has top end filter surface with a perimeter having at least one protrusion structure (33) and the filter holder (10) has a holder surface with a perimeter having at least one cooperating recess structure (22) that mates with said at least one protrusion structure (33). The keyed system has at least one cooperating recess structure including a first recess structure (22) comprising a plurality of axial recess portions (24) separated by ridges (28), and a first circumferentially-extending lock portion (40) having an open end above, and in mechanical communication with, said axial recess portions (24) and an opposing end comprising a rotation stop surface (41). At least one protrusion structure includes a first protrusion structure (33) that comprises a plurality of key protrusions (34) separated by spaces (128), and wherein said plurality of key protrusions (34), upon axial insertion of the filter (20) into the holder (10), slide up through said axial recess portions (24) to said open end of the first circumferentially-extending lock portion (40), and, upon angular rotation of the filter (20) in the holder (10), said plurality of key protrusions (34) of the first protrusion structure (33) slide into said opposing end of the first circumferentially-extending lock portion (40) of the first recess structure. The plurality of key protrusions (34) of the first protrusion structure comprises three key protrusions that are located within less than a 70 degree arc on said top end filter surface and wherein said three key protrusions all slide into said opposing end of the first circumferentially-extending lock portion upon angular rotation of the filter (20) to retain the filter (20) in the holder (10).
