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.
