Abstract
A filter cartridge for use in filters, for example, water filters, includes an inlet for water to be purified and an outlet for filtered water. Partitions within the cartridge define an elongated, tortuous water flow path between the inlet and outlet. Filter pads and activated carbon, or another suitable absorbent material, is disposed in the flow path. The cartridge of the present invention provides effective odor and taste filtering of the water because the water passes over a large area of filter surface as it travels from the inlet to the outlet.
