Crafted for longevity and engineered to maintain pristine water, this OEM-grade cartridge is designed to outperform standard replacements by delivering consistent flow, stronger debris handling, and easier maintenance—even in challenging salt and high-chlorine environments.
Why the FC-2725 is a smart choice for your filtration needs
- End caps with integrated fittings: Molded-in fittings simplify installation and removal and eliminate the need for PAD adapters that can reduce flow and complicate maintenance.
- Reinforced center cores for stability: Extruded PVC center cores with round holes distribute stress evenly, preventing collapse under heavy debris loading and extending time between cleanings.
- Premium filter media: Durable, high-quality polyester media delivers efficient filtration and longer life, helping you enjoy clearer water with less frequent replacements.
- Sharp pleat folds for deeper filtration: The unique synthetic fiber construction prevents bridging, allowing dirt to penetrate deep into the pleats for higher flow and easier cleaning.
- Wider, break-resistant bands: Keeps pleats evenly spaced and reduces flutter in turbulent housings, maintaining optimal filtration performance.
- Antimicrobial end caps: Reinforced, antimicrobial end caps help repel odor-causing bacteria and mold, extending cartridge life and keeping your system fresher in salt and chlorine-rich environments.
- Embossed part numbers for easy replacement: Clear identification helps with quick reordering when you’re stocking pool and spa supplies.
- Salt pool and high-chlorine compatible: Formulated to resist deterioration in challenging water chemistry, so you get better durability and sustained performance over time.
