Description

Filbur FC-3550 Spa/Pool Replacement Filter Cartridge is built for value-driven pool and spa owners who demand lasting filtration and minimal maintenance. As a trusted OEM leader in the USA, Filbur delivers cartridges engineered to outlast typical replacements, keep water crystal clear, and endure the rigors of salt and chlorine environments.

• End caps with integrated fittings: Molded-in fittings simplify installation and removal, eliminating the need for pad adapters that can reduce flow. The end caps are reinforced and treated with antimicrobial properties to resist odor-causing bacteria and mold, even in high-sanitizer systems.
• Reinforced center cores: Extruded PVC center cores provide superior stress distribution and higher debris loading, reducing the risk of cartridge collapse under heavy use and extending time between cleanings.
• Premium filter media: Durable polyester media delivers longer service life and consistent filtration. The unique sharp pleat folds prevent bridging, allowing dirt to penetrate deep into the folds for sustained flow and easier cleaning.
• Wider break-resistant bands: Broader support bands keep pleats evenly spaced, minimizing flutter in turbulent housings and preserving optimal flow and filtration performance.
• Antimicrobial protection: End caps and reinforced construction work together to help deter odor-causing bacteria and mold, supporting cleaner water in spa and pool applications.
• Embossed part numbers: Clear, embossed markings simplify identification and re-ordering, ensuring you always have the right FC-3550 cartridge on hand.
• Salt and chlorine-ready design: Formulated to resist deterioration in saltwater pools and high-chlorine environments, making this cartridge a dependable choice for modern spas and wet environments.

Practical tips to maximize performance: rinse the cartridge under cool water to remove loose debris, avoid harsh chemicals that can degrade the media, and replace when you notice rising pressure or reduced flow.
