Abstract
A water filtering pitcher with a pitcher with a top, a base and an inner wall surface extending between the top and the base to define an internal volume. A filter adapter is positioned within the internal volume of the pitcher, configured to couple to a water filter, and movable between a first position closer to the base and a second position closer to the top. At least one bias member configured to bias the filter upward is positioned between the filter adapter and the pitcher base. When a water filter is received through the top of the pitcher to the filter adapter and water is filtered from above the filter adapter through the water filter and into the base of the pitcher, the at least one bias member biases the filter adapter and water filter from the first position toward the second position.
