Abstract
A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.
