The Filbur FC-2340 Spa/Pool Replacement Filter Cartridge is engineered to deliver lasting performance where it matters most—crystal-clear water and fewer filter changes. Built by Filbur, the leading OEM filter manufacturer in the USA, this cartridge blends value with durable, heavy-duty filtration designed for both spas and pools.
-
Reinforced center cores — Extruded PVC center cores with round holes distribute stress evenly and prevent collapse under heavy debris loading, extending time between cleanings.
-
Antimicrobial end caps — End caps are reinforced and treated to repel odor-causing bacteria and mold, maintaining cleanliness in challenging salt and chlorine environments.
-
Premium filter media — Durable, high-quality polyester media ensures long life, better water clarity, and sustained filtration performance.
-
Sharp pleat folds — Unique synthetic fiber construction prevents bridging, allowing dirt to penetrate deep into the pleats for increased flow and easier cleaning.
-
Wider, break-resistant bands — These bands keep pleats evenly spaced, reduce flutter in turbulent housings, and support higher debris loads without compromise.
-
End caps with integrated fittings — Molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can reduce flow and hinder filtration.
-
Embossed part numbers — Clear, embossed identifiers make reordering quick and accurate, so you’re never guessing when it’s time to replace.
Designed for both saltwater and chlorine-heavy environments, the FC-2340 cartridge resists deterioration and maintains efficiency even in demanding spa and pool systems. Its reinforced center cores and antimicrobial features help sustain cleaner water and reduce maintenance frequency, making it an ideal choice for family pools, resort-style spas, and rental properties alike.
Who benefits most: spa owners wanting reliable, OEM-grade filtration; pool operators seeking longer-lasting cartridges; households with salt systems looking for durable, corrosion-resistant performance; anyone who values easy installation and straightforward maintenance.
To get the best results, rinse the cartridge with low-pressure water to remove loose debris and avoid high-pressure jets that can stress the pleats. Regular replacement with the FC-2340 ensures optimal flow, clear water, and peak filtration efficiency season after season.
