Description
Meet the Filbur FC-3135 Spa/Pool Replacement Filter Cartridge — a purpose-built cartridge designed to power clean, inviting water in home spas and pools. Built with durability and filtration finesse in mind, this cartridge stands out for long-life performance, even under saltwater and high-chlorine conditions, so you spend less time fiddling with filters and more time enjoying the water.
What sets the FC-3135 apart
- END CAPS with reinforced antimicrobial properties — the end caps are treated to repel odor-causing bacteria and mold, helping keep your filtration system fresher between cleanings. These caps are engineered to resist salt and chlorine attack, extending the life of the cartridge in challenging water chemistry.
- Extruded PVC center cores — exceptionally strong, with round holes that distribute stress evenly and prevent cracking or collapse under heavy debris loading. This means reliable performance even when your spa or pool experiences high filtration demand.
- Wider break-resistant bands — these reinforced bands maintain pleat spacing for optimal flow and filtration, reducing flutter and turbulence that can compromise performance.
- Premium polyester media — durable, easy to clean, and designed to preserve water clarity while maintaining efficient filtration across a wide range of contaminants.
- Sharp pleat folds — the synthetic fiber construction minimizes bridging, ensuring dirt penetrates deep into the folds for better filtration and easier cleaning.
- Embossed part numbers — for quick identification and easy re-ordering when it’s time to refresh your filtration setup.
- End caps with integrated fittings — molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can hinder flow.

- Consistent filtration efficiency, even in challenging water chemistry (saltwater pools, high-chlorine environments)
- Reliable fit and easy installation with integrated fittings, reducing maintenance steps
- Better protection against odor-causing mold and bacterial growth within the filter housing
Ideal use cases
This replacement cartridge is well-suited for:
- Residential spas and hot tubs that see frequent use
- Saltwater pools or spa systems where corrosion resistance and longevity matter

Tips for maximizing performance
- Rinse the cartridge with a garden hose to remove surface debris, then soak periodically to restore cleaning efficiency without damaging the pleats.
- Check the cartridge for cracks or torn pleats during routine maintenance; replace when you notice significant wear to maintain water clarity.
- Pair with compatible filter housings and follow manufacturer guidelines for flow rates to ensure optimal filtration without overloading the media.
