Product Description

Pentair Sta-Rite System 3 S8M500 Cartridge Pack 500 Sq Ft 170148

Renew a Sta-Rite System 3 S8M500 modular media filter with the genuine OEM 170148 cartridge pack. The pack contains both modules the S8M500 uses — the large outer cartridge and the small inner cartridge — for a complete 500 sq ft media change in one box.

🚩 PRO TIP: Replace both modules at the same time: the inner and outer cartridges age together, and fitting a new outer module over a worn inner one leaves filtration uneven. Hose the modules down from top to bottom at a 45-degree angle when you clean them, and never use a pressure washer — it damages the pleats.

FREQUENTLY ASKED QUESTIONS:

  • Which filter does the Pentair 170148 cartridge pack fit? The Pentair 170148 fits the Sta-Rite System 3 Modular Media S8M500 filter, the 25 in filter model rated at 500 sq ft.
  • What is included in the Pentair 170148 pack? The Pentair 170148 pack includes both S8M500 modules: the large outer cartridge 25022-0225S and the small inner cartridge 25021-0224S.
  • Can I replace just one module instead of the whole 170148 pack? The two modules are also sold individually as 25022-0225S and 25021-0224S, but the 170148 pack replaces both together so the full 500 sq ft of media is renewed at once.
