A filter system including a filter assembly having a housing, a filter element disposed within the housing, an inlet passege extending through the housing, and an outlet passage extending through the housing, the outlet passage in communication with the inlet passage through the filter element; and an element condition monitoring assembly including an inlet pressure transducer in communication with the inlet passage, an outlet pressure transducer in communication with the outlet passage, and a microprocessor linked to the inlet and outlet pressure transducers. The inlet pressure transducer gauges the pressure transducer gauges the pressure in the inlet passage, and the outlet pressure transducer gauges the pressure in the outlet passage. The microprocessor calculates a pressure differential between the inlet and outlet pressure and calulates an element condition status using at least one element condition parameter, which may include the pressure differential.
