Abstract: A filtration cartridge faucet assembly contains a filtration body that is concealed beneath a sink deck through the use of an escutcheon mount. The escutcheon mount permits access to a renewable filtration core from above the sink deck while concealing and protecting the filtration body.

Abstract: A dual product outlet fitting is provided which permits discharge of a first fluid and a second fluid without mixing through a shell cover.

Abstract: A faucet mounted water filtration device (100) includes an end of life indicator assembly (130) having a flow totalization mechanism (600), a reset mechanism (602) and a flow restriction mechanism (604) coaxially aligned with an indicator assembly (130). A torsion spring (634) and compression spring (644) cooperate for automatic disengagement and resetting of the flow totalization mechanism and the flow restriction mechanism. A planetary gear reduction system 606 provides a 3,000,000:1 gear reduction in the flow totalization mechanism.

Abstract: A faucet-mounted water filtration device includes a gate valve that is used to select between discharge options. The gate valve contains a thumb rest which is configured to allow manual valve actuation while supportedly engaging a user's thumb. First discharge option includes a conventional bottom discharge into a sink. A second discharge option exists as a water fountain that is formed as a compact, integral feature of the water filtration device. A flow indicator permits a user to check whether the filtration cartridge is working properly.

Abstract: A filtration cartridge (20) uses a swage channel (50) to form a water-tight seal between a sealing element (26) and a semi-rigid filter (28).

Abstract: An efficient, low pressure drop biocide cartridge is provided for destroying viral and bacterial pathogens in water from untreated water sources along a lengthened flow pathway including a critical plenum for controlling the speed of water throughput. In a first pathway, water is percolated through a turbulatable bed of biocidally-effective material. In flow pathway, channeling and pressure drop are reduced by radial flow across a columnar bed presenting a large surface area at an outer diameter. The cartridge may be connected with a lightweight hand-held pump. A sealing strap is provided for wet storage of any biocide cartridge.

Abstract: A portable, manually-operated water filtration pump for purifying water. The pump includes an inexpensive, disposable filter cartridge which can be easily changed when the filter elements are no longer effective. The pump uses a lever to actuate a double-acting piston. The lever is collapsible to one side of the pump for compact storage. The filter cartridge is a tubular cylinder having an inner bore forming the pump cylinder. A cylindrical mechanical filter is concentric with and adjacent to the inner bore to filter out particulates larger than 0.3 microns. A fluidized granual activated carbon filter surrounds the mechanical filter to absorb halogen and halogen-related compounds such as herbicides and pesticides. The pump pumps filtered water into a bottle adaptor which will fit most standard water containers. A prefilter is provided to screen out large particulates from the pump to enhance the life of the filter elements.
