Description
Filbur FC-2390 Spa/Pool Filter Cartridge (C-4950) is built to outlast ordinary replacements while delivering crystal-clear water for your spa or pool. As a trusted OEM-style solution, this cartridge fits standard housings that accept FC-2390 / C-4950 models, offering durable filtration you can rely on day after day.
Why this cartridge stands out
- Reinforced center cores—extruded PVC cores provide even stress distribution and higher debris loading, reducing the risk of collapse under heavy usage.
- Premium filter media—durable polyester media delivers longer life, easier cleanability, and consistently clean water.
- Antimicrobial end caps—treated to repel odor-causing bacteria and mold, with added strength to resist wear in demanding environments.
- Integrated fittings on end caps—molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can impede flow.
- Wider break-resistant bands—keeps pleats evenly spaced, reduces flutter, and maintains optimal flow even in turbulent housings.
- Sharp pleat design with minimal bridging—the synthetic fibers prevent bridging, allowing dirt to penetrate deep into the pleats for better filtration and easier cleaning.
- Embossed part numbers—clear identification for quick reordering and hassle-free maintenance.
