15. A refrigerator comprising:
a filter having a protrusion extending therefrom;
a receiver defining a cavity configured to receive the filter;
a manifold configured to (i) engage an opposing end of the filter relative to the protrusion via axial rotation of the filter relative to the manifold, (ii) pivot upward within the cavity to transition the filter to an activated position, and (iii) pivot downward within the cavity to transition the filter to a deactivated position; and
a cam (i) disposed within the cavity, (ii) configured to interfere with the protrusion in response to partial axial rotation of the filter relative to the manifold to prevent the filter from pivoting upward to the activated position, and (iii) configured to provide clearance for the protrusion in response to full axial rotation of the filter relative to the manifold to facilitate the filter pivoting upward to the activated position.
