Description
Meet the Filbur FC-1440 Spa/Pool Replacement Filter Cartridge—a value-forward, OEM-grade filtration solution built to deliver consistently clean water and longer filter life. As a leading U.S. manufacturer of OEM filters, Filbur designs cartridges that stand up to saltwater environments, high chlorine levels, and heavy debris without compromising performance.
Why the FC-1440 stands out
- Reinforced center cores: The strongest extruded PVC center cores provide even distribution of stress and higher debris loading, helping prevent collapse under heavy loading and extending time between cleanings.
- End caps with antimicrobial treatment: The end caps are reinforced and treated to repel odor-causing bacteria and mold, delivering more hygienic filtration and longer cartridge life in challenging water conditions.
- Premium filter media: Durable, efficient polyester media delivers longer life, clearer water, and consistently strong filtration performance across multiple spa or pool cycles.
- Sharp pleat folds: Specialized synthetic fibers prevent bridging, allowing dirt to penetrate deep into the pleats for better flow and easier cleaning.
- Integrated fittings on end caps: Molded-in fittings enable easy installation and removal, eliminating the need for PAD adapters that can reduce flow and hinder filtration.
- Wider break-resistant bands: Keeps pleats evenly spaced, reducing flutter and maintaining optimum flow even in turbulent housing environments.
- Embossed part numbers: Clear, embossed identifiers simplify identification and re-ordering so you can keep your spa or pool running smoothly.
- Salt and chlorine resilience: Advanced formulation resists deterioration from salt pools and high chlorine levels, making it a reliable choice for diverse water chemistries.
