ABSTRACT:
A faucet mounted water filtration system with a filter life monitor includes a filter housing with a flexible cap which deflects upon introduction of water into the housing. The deflection of the cap closes a switch on an electrical circuit which counts the time the water is flowing through the housing. Once a predetermined amount of time accumulates, the circuit generates a message to inform the user that the filter needs replacement. The invention further includes a selector switch on the electrical circuit for signaling the circuit to count one of two predetermined amounts of time prior to generating a message.
