Embedding variable slit width embossed filter media packs

A method of manufacturing a filter cartridge, the method comprising:

• creating a variable width to a filter media pack which comprises a filter media sheet, the filter media pack having an inlet face, an outlet face, opposite first and second sides, opposite first and second ends, the sides and the ends extending transversely between the inlet face and the outlet face, with panels of the filter media sheet extending between the inlet face and the outlet face, the variable width extending between opposed ends such that different members of at least some of the panels have a different width with a widest member of the panels providing widest width and a narrowest member of the panels providing narrowest width, with the widest width greater than the narrowest width by at least 1.0 centimeter, in a manner that at least the first end bulges outwardly or inwardly from the opposite sides to define a first bulged face;
• and
• embedding a first adhesive end wall into the first bulged face at the first end to seal the first bulged face;
• and
• embedding a second adhesive end wall into the second end as a discrete adhesive body apart from the first adhesive end wall.

A filter cartridge, comprising:

• a filter media pack having an inlet face, an outlet face, and ends extending transversely to the inlet and outlet faces, each of the ends having an external non-planar, curved or multifaceted geometry;
• a pair of end caps located against each end, each end cap having an internal surface with a geometry closely matching the geometry of the associated filter media pack end;
• and
• a potting adhesive disposed between and fixing the filter media pack and the end caps together;
• and
• wherein the first end cap and the second end cap are spaced apart and provided as separately potted end caps.
