Product details
The Sta-Rite 25022-0201S is the large outer filter cartridge for the System 3 S7M120, rated at 200 square feet of filter area. It is the outer half of the Modular Media 300 element set.
How the System 3 element set works
The System 3 does not use a single cartridge. A large outer element carries most of the area, and a smaller inner element sits inside it. This part is the outer one. The inner replacement for the S7M120 is 100 square feet and is ordered on its own, which is why most owners renewing a tired filter buy both at once.
Before you order
This cartridge is listed for the S7M120. The wider System 3 SM parts group also covers the S7M400, S8M150 and S8M500, and those models take different element sizes, so read the number off your old cartridge or the filter label rather than going by the family name.
Replace rather than clean once a full soak stops restoring pressure, or once the pleats are matted or split. A worn element sends fine dirt straight back to the pool no matter how often you rinse it.
