27002-0100S Pool Filter Cartridge Replacement - 100 sq.ft Clean Water

In this review of the 27002-0100S pool filter cartridge the bottom line is simple: it fits PLM100 and System 2 modular media housings and delivers noticeably cleaner water with minimal fuss. Installers and weekly maintainers will appreciate that the cartridge is sized to the correct dimensions and ships with an air bleed assembly, and the main reason to buy is the large 100 sq.ft filtration area combined with a trilobal fabric that captures more debris than standard cartridges.

Key Features

• Perfect Compatibility: Sized at 18.30 in high and 12.90 in diameter, it fits sta-rite PLM100 and system 2 modular media pool filters without modification.
• High Filtration Area: The cartridge provides 100 sq.ft of media area, giving a larger contact surface to remove fine particles compared with ordinary cartridges.
• Dirt Locking Technology: The latest fabric construction traps hair, sediment, sand and algae more effectively, reducing cloudiness between cleanings.
• Trilobal Fabric Design: The upgraded trilobal filtration cloth increases surface area and improves washability so debris rinses out with water pressure.
• Durable End Caps: Chlorine-resistant high pressure end caps and reinforced fold bands resist stretching and extend service life.
• Includes Air Bleed Assembly: The kit includes one air bleed assembly so the cartridge can be primed and vented during installation.

Who It's For

The 27002-0100S is best for pool owners who use compatible PLM100 or System 2 modular media filters and want an economical replacement that matches OEM sizing while offering improved filtration area. It suits regular maintainers who prefer cartridges that rinse clean quickly and reduce the frequency of full replacements.

It is less suitable for people who need a branded original part from the original manufacturer or for systems that require a different height or diameter. Those who want aftermarket parts verified by the original brand should look elsewhere.
