Experience consistently clear water and dependable performance with the Filbur FC-2940 Spa/Pool Replacement Filter Cartridge. Built for value without compromising filtration power, this cartridge is designed to endure the demands of both spa and pool environments—delivering lasting debri removal and easier maintenance.
Why this FC-2940 cartridge stands out
-
Reinforced extruded center cores: Absolutely the strongest support structure, with round holes that evenly distribute stress and debris loading to prevent cartridge collapse and extend service intervals.
-
Premium polyester filter media: Durable, cleanable, and capable of sustaining efficient filtration for longer. Sharp pleat folds prevent bridging, allowing dirt to penetrate deep into the folds for steady, high-flow filtration.
-
Antimicrobial end caps: Reinforced end caps treated to repel odor-causing bacteria and mold, providing antimicrobial protection while resisting deterioration in salt pools and high-chlorine conditions.
-
Wider break-resistance bands: Keep pleats evenly spaced to maintain optimum flow and prevent flutter from housing turbulence, helping you get longer life between cleanings.
-
End caps with integrated fittings: Molded-in fittings make installation and removal straightforward, eliminating the need for PAD adapters that can restrict flow and filtration.
-
User-friendly identification: Embossed part numbers streamline ordering and reordering, so you’ll always grab the right replacement.
