Description

The Pleatco XtremeBlue A11 replacement cartridge is engineered for Pentair Clean & Clear 500 and 550 filter systems. With approximately 115 square feet of filtration area, it delivers high-capacity performance while maintaining strong, efficient water flow.

Built with advanced point-bonded filtration media, it captures more dirt and debris while maintaining efficient flow. PurePleat™ technology keeps pleats evenly spaced, preventing collapse and allowing debris to remain on the surface for faster rinsing and easier maintenance.

The antimicrobial-treated XtremeBlue™ media helps inhibit bacteria growth, extending cartridge life and maintaining cleaner filtration conditions. A reinforced Free Flow Core improves circulation and reduces operating pressure for better system efficiency.

Pro Tip

For best performance in multi-cartridge systems, replace all cartridges at once and keep a spare for quick swaps during cleaning.

Installation Tips

Turn off and relieve system pressure before opening the filter. Remove the old cartridge, rinse or replace, and reinstall securely. Clean regularly to maintain optimal flow and filtration performance.
