About This Item
The Pentair Small Cartridge (25021-0224S) is the replacement 209 sq. ft. inner filtration module for the System 3 Modular Media Filter, model S8M500.
This cartridge module serves as the inner filtration media for the System 3 modular tank, using a shallow-pleat design that maximizes dirt-holding capacity within the modular tank housing. Because the media installs as a self-contained module, it can be replaced without disassembling or replacing the filter tank itself.
This is the smaller, inner cartridge for the S8M500. For the matching larger, outer cartridge, see part number 25022-0225S. Replace both to complete your filter service.
For a combo back of both filter cartridges, see the combo pack: 170148

Poolaroo Pro Tip
The shallow-pleat design on this module is built for quick service — a hose-down is typically enough to clear routine debris buildup between full cleanings, helping maintain longer filter cycles on your System 3 filter.
