Abstract
A water filter assembly having a manifold with a rotatable cylinder in which a filter cartridge is removably received is provided. The filter assembly has a noise generator adjacent to the rotatable cylinder of the manifold. When the filter cartridge with the rotatable cylinder is rotated between an installed position and an uninstalled position, the noise generator creates an audible noise. The noise may indicate, for example, that the filter cartridge may be removed from the manifold.
