Abstract

A filtering apparatus and replaceable filter assembly including an electronic filter identification system having an electronic label on the filter and a read-out mechanism on the filtering apparatus. The read-out mechanism is connected to a control unit of the filtering apparatus and the control unit is influenced by the read-out mechanism. The control unit may be actuable only upon disposing a filter in the filtering apparatus having a proper or predetermined electronic label. The filter identification system may also be interactive. The electronic label on the filter includes a read/write memory which can store the number of operating hours of the filter.
