The invention pertains to a process and a device for cost-oriented monitoring and/or display of the operating state of a replaceable or regenerable, fluid (7) -traversed conditioning device (1), particularly a filter (4), in an overall system. According to the invention sensors (9; 10; 11) are used to measure continuously or at intervals at least one measurement value from which of the exhaustion state of the conditioning device is derived according to the following steps: the measurement value is supplied to an evaluation electronic unit (16); the exhaustion state of the conditioning device (1) is determined from the measurement values; by mmans of the functional dependencies and/or data stored in the evaluation electronic unit (16), the effects of the exhaustion state of the conditioning device (1) on the operating costs of the overall system are at least approximated; by means of the functional dependencies and/or data stored in the evaluation electronic unit (16) the cost of replacing or regenerating the conditioning device (1) is determined and compared with the effects of the exhaustion state on the operating costs; a display instrument (24), in particular a display instrument associated with the conditioning device (1), signals the point in time at which replacement or regeneration is overall more cost-effective than continued operation to the point of complete technical exhaustion of the conditioning device (1).
