1. A method of using a filtration system comprising:
guiding, by alignment rail and mating boss, a filter cartridge into a manifold housing;
aligning a filter magnet with a corresponding manifold magnet;
rotating, by attractive magnetic forces, the manifold magnet upon rotation of the filter cartridge into an installed position to generate a torque force on the manifold magnet; and
actuating, by the torque force, a manifold valve.
