The OEM Pentair replacement cartridge R173576 | 179135 features certified safe materials for clean, fresh, and clear water, with thicker filtration fabric, heavy chlorine resistance, break-resistant end caps, and reinforced center support. Its uniformity and high-performance trilobal fabric provide superior capacity compared to common point-bond fabric, ensuring optimal filtration performance.
Please note: You may notice that the label or band on this cartridge displays Pleatco branding rather than the Pentair name. This is completely normal — Pentair acquired Pleatco, one of the world's leading pool filter cartridge manufacturers, and Pleatco now serves as Pentair's OEM manufacturing arm for replacement cartridges. The cartridge you receive is 100% genuine Pentair OEM — manufactured by Pleatco to Pentair's exact specifications. The Pleatco branding on the physical product does not affect authenticity, fit, or filtration performance in any way.
