摘要： The invention provides a device comprising (i) a filter having an autonomous mechanical end-of-life mechanism, (ii) a current path for an electrical or liquid current, wherein: the filter comprises an ion-exchange resin, wherein the ion-exchange resin undergoes a dimensional change when ion-exchanging; and the ion-exchange resin is arranged such that over a threshold value of the dimensional change the dimensional change of the ion-exchange resin mechanically adjusts the current through the current path.
