About This Item
The Pentair Small Cartridge (25021-0200S) is the OEM replacement 100 sq. ft. inner filter module for the Sta-Rite System 3 Modular Media Filter, model S7M120.
This module is the internal filtration media component of the System 3 modular media filter system. It installs inside the existing System 3 tank housing, allowing the filter media to be serviced or replaced without removing or replacing the outer tank shell.
This is the smaller, inner cartridge for the S7M120. For the matching larger, outer cartridge, see part number 25022-0201S. Replace both to complete your filter service.
For a combo back of both filter cartridges, see the combo pack: 170145

Poolaroo Pro Tip
Because this module drops into the existing System 3 tank shell, replacing it doesn't require any plumbing changes to the tank itself. Rinse the media module regularly and inspect the tank o-ring seal at the same time to help maintain consistent flow between filter cycles.
