Meet the Filbur FC-2930 Spa/Pool Replacement Filter Cartridge — a 75 sq ft, high-capacity filter designed to keep water crystal clear while standing up to salt and high-chlorine spa environments. Ideal for homes using Cal Spas, Leisure Bay/Rec Whs, Sunbelt Spas, Waterway Bottom models, and related systems, it combines robust construction with precise filtration for easier, longer-lasting maintenance.

• Filtration Area: 75 sq ft of media to capture more debris per cycle and support longer run times between cleanings.
• Dimensions: 23-5/8" length and 4-15/16" outer diameter ensure a durable, high-flow profile compatible with common spa housings.
• Configuration: Top Load, In-Line design with 2-1/8" top and bottom openings for straightforward installation in a wide range of filter systems.
• Media & Construction: 3 oz polyester filtration media delivers reliable, consistent filtration and backwash performance.
• Durability: Reinforced center cores distribute stress evenly, helping prevent cartridge collapse under heavy loading and extending time between cleanings.
• End Caps: Antimicrobial end caps treated to repel odor-causing bacteria and mold, with added reinforcement for salt and high-chlorine environments.
• Flow Stability: Wider support bands keep pleats evenly spaced, reducing flow turbulence and pleat flutter for steadier filtration.
• Easy Installation: End caps with integrated fittings allow quick installation and removal without needing PAD adapters, preserving flow and filtration efficiency.
• Center Core: Extruded PVC center cores provide exceptional strength and load-bearing capacity, resisting cracks and collapse.
• Compatibility: Specifically designed for Cal Spas, Leisure Bay/Rec Whs, Rec Whs/Leisure Bay, Sunbelt Spas, and Waterway Bottom models.

Filbur’s FC-2930 stands out with antimicrobial end caps and reinforced internals, delivering clearer water and longer filter life in demanding environments. It’s an especially smart choice for homes with salt systems or elevated sanitizers, where standard filters wear out faster. This cartridge helps you reduce mid-season replacements, simplify maintenance, and keep your spa ready for use with less effort.

Practical tips for optimal performance: rinse the cartridge before first use to remove loose fibers, backwash regularly to maximize life, and keep water chemistry balanced (pH, alkalinity, sanitizers) to maintain filtration effectiveness. Replace the cartridge when you notice reduced flow or diminishing water clarity to maintain peak spa performance.
