A control system (204) for monitoring a filter (2a, 2b) in a subsea control module (SCM) (202) of an underwater hydrocarbon well is presented. The control system includes an upstream pressure transducer (10a, 10b) disposed upstream of a filter of the SCM and configured to sense an upstream pressure. The control system further includes a downstream pressure transducer (8) disposed downstream of the filter and configured to sense a downstream pressure. Furthermore, the control system includes a subsea electronics module (SEM) (11) coupled to the upstream pressure transducer and the downstream pressure transducer. The SEM is configured to determine average pressure differential values at different instances based on the upstream pressure and the downstream pressure. Moreover, the control system also includes a master control station (MCS) (112) coupled to the SEM and configured to predict a filter maintenance generate an indication of the predicted filter maintenance due time for an operator of the underwater hydrocarbon well.
