5. A method of interconnecting a filter cartridge and a mating filter manifold, comprising:
inserting said filter cartridge into a sump housing of said mating filter manifold, said filter cartridge comprising a housing having a body, a bottom surface, a fluid ingress port and a fluid egress port wherein each of the fluid ingress port and the fluid egress port extend axially upward from a top surface of the housing and off-axial center of the housing body, a protrusion extending radially outwards from said housing body, and a first magnetic structure located on said housing body or encompassed within and forming a portion of an outer wall surface of said housing body, said first magnetic structure including a polymagnet having a plurality of field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to a predetermined alignment of said field emission sources, the first magnetic structure polymagnet having a radially outwardly-facing surface comprising the plurality of field emission sources which presents in a direction away from a center axis of the filter cartridge body;
moving said filter cartridge within said filter manifold sump housing in a first direction parallel to the center axis of the filter cartridge body;
engaging the fluid ingress port and fluid egress port of the filter cartridge with receiving ingress/egress ports of the manifold;
aligning said first magnetic structure plurality of field emission sources with a plurality of field emission sources of a complementary or paired second magnetic structure disposed within a latch blocking mechanism or holder of said filter manifold sump housing such that a magnetic shear force is generated, said latch blocking mechanism in slidable communication with a latch being actuable under a first resilient biasing mechanism and said latch blocking mechanism being biased toward said latch under a second resilient biasing mechanism applying a force to said latch blocking mechanism or holder;
moving, by non-physical magnetic shear force, said latch blocking mechanism away from said latch; and
actuating said latch in a second direction to contact said filter cartridge protrusion, thereby securing said filter cartridge to said manifold, said second direction being different from said first direction.
