Product Overview

The Pentair 25022-0201S cartridge is a primary filtration component used in Sta-Rite System 3 modular media pool filters. Installed inside the filter housing, the cartridge traps debris and contaminants as water flows through the pleated filtration media, helping maintain clear and balanced pool water.

This cartridge serves as the large outer module in the S7M120 System 3 configuration and works together with the smaller inner cartridge to provide the filter’s total filtration capacity.
