摘要： A pitcher or carafe housing is provided that has a raw water reservoir. A high performance filter receives raw water from a lower portion of the reservoir. The water is preferably received at or travels through a water entry tube to the back and bottom of the filter. In about 1-3 minutes the water percolates through the filter element, until it reaches a water exit port. A pouring chamber may be provided at the side of the pitcher for receiving the water from the water exit port, so that the water will continue to be treated and flow up into the pouring chamber until the water level equalizes in height in the reservoir and the pouring chamber. The filter and its housing may be placed into and removed from the inside of the raw water reservoir, or the filer housing may be side loaded. The filter media may be a polyester non-woven mat with a weight of 4-7 oz./yd.2 impregnated with carbon or zeolite and subject to compression between about 25-75% (e.g. about 50%).

摘要： A dual flow filter provides meaningful flow through the base of a monolithic carbon composite filter, creating axial flow, while concurrently providing radial flow through the side walls of the monolithic carbon composite filter element. The filter provides consumers with a more rapidly flowing product offering less pressure drop, i.e., resistance to flow, than other portable filters that have been offered to the consumer, while enhancing the simplicity, utility and esthetics of the product.

摘要： A water treatment system including a bottle with a neck, a tube for disposition within the bottle and having water treatment material (such as activated carbon for removing a significant portion of the chlorine in tap water) associated with it, and a cap. The bottle is filled by causing water to flow through the tube, through the water treatment material, into the bottle. When filled, the bottle neck is closed off by screwing the cap into contact with the neck, the cap closing off the tube so that water does not flow through the tube out of the bottle, but rather exteriorly of the tube through openings in a cap first element and between the tube and the neck. A second element of the cap releasably closes off the water flow openings. In order to prevent leakage of water from the bottle even when tilted or dropped, the cap second element may be twisted with respect to the first element to lock the elements together in the closed position, and this—combined with the substantially elastomeric material sealing ring between the cap first element and the bottle—substantially prevents water from flowing out of the neck of the bottle. The water treatment material may easily be changed by removing a canister from an end of the tube and inserting a new canister into contact with the tube.
摘要翻译：一种水处理系统，包括具有颈部的瓶子，用于在瓶子内配置的管子，并且具有与其相关联的水处理材料（例如用于除去自来水中的大部分氯的活性炭）和盖。通过使水通过管子通过水处理材料流入瓶子来填充瓶子。当填充时，通过将盖拧到与颈部接触来封闭瓶颈，盖关闭管，使得水不会通过管从瓶中流出，而是通过帽中的开口穿过管的外部第一元素和管与颈之间。帽的第二元件可释放地封闭水流开口。为了防止水即使在倾斜或掉落时也从瓶中泄漏，盖帽第二元件可以相对于第一元件扭转，以将元件锁定在关闭位置，并且与基本上弹性体的材料密封环在瓶盖第一元件和瓶之间，基本上防止水从瓶的颈部流出。可以通过从管的端部移除罐并将新的罐插入与管接触来容易地改变水处理材料。

摘要： A filter assembly for use with a bottle having a circular cross-section neck or open end includes a fine filtration media having a mean pore size of about 1-3 microns and capable of removing contaminants of 3-4 micron size and larger, and an inner filtration media disposed radially inward of the fine filtration media. The inner filtration media includes activated carbon, preferably a porous activated carbon/plastic matrix having a porosity of between about 10-150 microns. The outer housing contains the fine filtration media and the inner filtration media, and is dimensioned to pass through the neck or open end of the bottle. The fine filtration media preferably comprises sheets on opposite faces of a microfiber filter media formed of glass microfibers of varying cross-sectional diameters, with the fine filtration media in a pleated or accordion configuration. A filter assembly may also be provided having a spring pressed straw. The filter assembly may also include a generally tubular plastic housing with a number of ribs each having an inner surface and an outer surface at least 50% larger than the inner surface. The filter element may also be provided comprising a porous rigid matrix of at least 35% activated carbon, styrene, and metal removing polymer bound to the styrene. Also the filter assembly may have a filter element housing extending upwardly from and operatively connected to a cap and having a maximum cross-sectional area at least 20% larger than the cap top area, for example in the form of a disc or a sphere. The filter may be formed by mating hemispherical portions, and the housing may have a novelty configuration.
