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.

Flow totalization, reset, and restriction mechanism for use in

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.

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).

Filtration cartridge

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.
