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.
