ELECTRONIC INTERFACE FOR WATER FILTER

A water filter includes a filter unit having a body portion adapted to be rotatingly received into a filter head assembly. An engagement protrusion extends from the body portion and is adapted for reception in a complementary receiver in the filter head assembly. An electronic device is disposed on the filter unit having a memory storage unit. A laterally extending key member is disposed on the body portion between the first engagement surface and the second engagement surface. The laterally extending key member is adapted to reposition an interference member from an interference position, whereby the body portion can be fully inserted into the filter head assembly to a non-interference position, whereby the body portion can be fully inserted into the filter head assembly. 1. A fluid filter comprising:a body portion adapted to be received into a filter head assembly of an appliance, wherein receipt of the body portion in the filter head assembly triggers a reconfiguration of a filter system of the appliance;an engagement protrusion extending from the body portion and adapted for reception in a complementary receiver in the filter head assembly;an electronic device disposed on the filter having a memory storage unit, wherein the memory storage unit stores at least filter life data to define current filter life data; anda data relay disposed within the electronic device, wherein triggering of the reconfiguration of the filter system is defined by the data relay delivering the current filter life data to the appliance.2. The fluid filter of claim 1 , wherein delivery of the current filter life data is via a wired connection with the filter head assembly.3. The fluid filter of claim 1 , wherein the reconfiguration of the filter system is further defined by a control unit and a user interface of the appliance utilizing the current filter life data delivered from the data relay of the electronic device.4. The fluid filter of claim 1 , where the current filter life data ...
