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.

[ We claim:] [10.] A water filtration system with a filter life monitor comprising:a housing with an inlet, an outlet, a cap end, a flexible cap for sealing said cap end, and a cover engaged with said cap end such that said cover encloses said cap end and said flexible cap;at least one contact surface on said flexible cap;a water filter media disposed within said housing;directing means for directing fluid flow through said housing such that fluid pressure causes a deflection of said flexible cap;means for creating a constant water flow into said housing;an electrical circuit associated with said housing, said electrical circuit having at least a first electrical contact and a second electrical contact, said first and second electrical contacts being in an operational relationship with said contact surface on said flexible cap such that the deflection of said flexible cap results in electrical continuity between said first electrical contact and said second electrical contact thereby completing said electrical circuit; andsaid circuit further having a counting means for counting the time said circuit is complete and a means for generating a message when said circuit is complete for a predetermined amount of time.
