-
Reinforced extruded PVC center cores — round holes and robust construction distribute stress evenly, preventing cartridge collapse under heavy debris loading and increasing time between cleanings.
-
Antimicrobial, reinforced end caps — end caps treated to repel odor-causing bacteria and mold while strengthened for harsher pool chemistry; integrated end-cap mesh adds durability and long-term integrity.
-
Premium polyester filter media — durable, efficient filtration that extends filter life and maintains water clarity; sharp pleat folds prevent bridging, enabling dirt to penetrate deep into the folds for steady flow and easier cleaning.
-
Wider, break-resistant bands — keep pleats evenly spaced, reducing flutter from turbulence and maintaining optimum flow even under heavy use.
-
End caps with integrated fittings — molded-in fittings provide easy installation and removal, eliminating the need for PAD adapters that can impede flow and filtration.
-
Embossed part numbers — clear identification for quick re-ordering and hassle-free maintenance planning.
