Description
Filbur FC-1340 Spa/Pool Replacement Filter Cartridge is engineered to deliver cleaner water and longer filter life for your hot tub, spa, or pool. Built to outperform standard cartridges, it combines durable media with advanced design features that stand up to saltwater, chlorine, and heavy debris, so you spend less time maintaining and more time enjoying clear water.
- Reinforced center cores: Extruded PVC center cores with round holes for even distribution of stress, preventing collapse under heavy debris loading and extending the time between cleanings.
- Premium filter media: Durable polyester media provides strong filtration, easy cleanability, and sustained water clarity over the life of the cartridge.
- Antimicrobial end caps: Reinforced end caps treated to repel odor-causing bacteria and mold, offering antimicrobial protection and resilience in salt and high-chlorine environments.
- Wider break-resistant bands: Broader bands keep pleats evenly spaced, reduce flutter in turbulent housings, and maintain optimum flow for consistent filtration.
- Sharp pleat folds: Specialty synthetic fiber construction prevents bridging, allowing dirt to penetrate deep into the pleats for higher flow and easier cleaning.
- End caps with integrated fittings: Molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can impede flow and filtration.
- Embossed part numbers: Clear, embossed identifiers for quick identification and easy re-ordering, so you can replace without guesswork.
Designed with durability in mind, the FC-1340 cartridge is built to endure the demands of both saltwater pools and spas with elevated chlorine levels. Its enhanced debris loading and sustained flow contribute to longer intervals between cleanings, helping you maintain sparkling water with less effort.
