Abstract
A portable liquid filtration system includes a container having a filtering assembly therein and an arrangement for indicating the number of times that the cap has been fitted to the container in order to determine the remaining useful life of the filter. The indicator includes a clutch plate having downwardly extending projections that mate with a plurality of upwardly extending projections on the filtering assembly top . The cap includes a vent and may include an arrangement to ensure that the filter is positioned correctly therein. Preferably, the indicator releases the filtering assembly after a predetermined number of uses that approximates the life of the filter.
