Abstract
An indicator for the status of the filter is provided. The indicator comprises at least one erodable member in contact with the source fluid and a visual indication arrangement that permits a viewer to gauge the appearance of the erodable member to thereby gauge the filter status. The erodable member is eroded by interaction with the fluid or with an element within the fluid. The indicator may be incorporated as an integral component of a filter or may be a stand-alone device to be incorporated into a filter or filtration system.
