Abstract

In one example, a water pitcher is provide that includes a candle defining a receptacle with a fluid inlet and a fluid outlet and configured to removably receive a filter cartridge. As well, the candle includes a filter seat that cooperates with the filter cartridge to form a substantially fluid-tight seal when the filter cartridge is positioned in a sealing range defined by the candle. A filter management element is configured and arranged so that when the filter cartridge is aligned in the receptacle but resides outside the sealing range, and a force is exerted on the filter management element, the force is transferred to the filter cartridge by way of the filter management element so as to move the filter cartridge into the sealing range.
