摘要 A water filtration system, and a filter and timer therefor. The system includes a primary container defining a holding chamber and a secondary chamber defining a filtering chamber at least partially within the holding chamber but spaced above the bottom wall of the holding chamber. The filter assembly is removably connected to the secondary container and comprises a cannister containing a filter disposed generally below the lower end of the filtering chamber, the cannister having inlet means communicating with the filtering chamber and outlet means disposed below the inlet means and communicating with the holding chamber. The timer is connected to the filter and includes a tube with an indicator movable longitudinally therein through a non-gaseous fluid having a specific gravity different than that of the indicator.
