1. A filtration system comprising:
a filter manifold having a rotatable manifold magnet, a mechanical stop in proximity to said manifold magnet, a valve, and a shroud; and
a filter cartridge having a housing body and a stem extending from a top portion of said housing body, and a filter magnet located on or within said stem;
wherein said manifold magnet is attached to or housed within a rotatable structure having an extension or tab, such that said tab is in mechanical communication with said manifold mechanical stop at predetermined points of rotation of said manifold magnet;
wherein said manifold magnet and said filter magnet are interconnected via magnetic attraction with one another upon insertion of said filter cartridge into said shroud, and upon rotation of said filter cartridge, said manifold magnet rotates and is capable of actuating said valve.
