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.
