Description
Meet the Filbur FC-2790 Spa/Pool Replacement Filter Cartridge, the trusted Proline replacement cartridge you’ve been seeking for crystal-clear water and hassle-free maintenance. Also known as the P-8325, this Filbur cartridge is built to outlast ordinary filters while delivering consistently clean, inviting spa or pool water. As a leading OEM filter manufacturer in the USA, Filbur combines durability, performance, and practical design you can count on season after season.
Engineered for durability and precise filtration
- Reinforced center cores: Extruded PVC center cores with round holes distribute stress evenly, dramatically reducing the risk of collapse under heavy debris loads and increasing time between cleanings.
- Premium media with sharp pleat folds: A high-quality polyester media maintains strength and flow, while sharp pleat folds prevent bridging so dirt can penetrate deep into the pleats for efficient filtration and easier cleaning.
- Antimicrobial end caps: End caps engineered with antimicrobial properties resist odor-causing bacteria and mold, helping keep your filter and water fresher between cleanings.
- Wider break-resistant bands: Extra-wide bands keep pleats evenly spaced, reducing flutter from turbulence and preserving optimal flow through the cartridge.
- Integrated fittings: Molded-in fittings remove the need for PAD adapters, simplifying installation and maximizing flow right out of the housing.
- Salt and chlorine resistance: Advanced formulation withstands the harsher conditions of saltwater pools and high-chlorine environments, extending filter life in demanding setups.
- Easy identification for replacement: Embossed part numbers make ordering replacements quick and accurate, minimizing downtime.
Why this cartridge matters for your water
The FC-2790 is designed to deliver longer filter life with dependable performance. By preventing filter collapse under heavy debris and maintaining consistent flow, you’ll experience clearer water, less frequent cleanings, and fewer filter-related headaches. This isn’t just a replacement part—it’s a maintenance upgrade that keeps your spa or pool running smoothly year-round.
Use cases and ideal setups
- Residential spas and in-ground pools using Proline filtration systems that require FC-2790 (P-8325) cartridges.

Installation, maintenance, and care
For best results, install the FC-2790 cartridge in compatible Filbur or Proline housings, then follow a regular maintenance routine:
- Inspect flow: If flow decreases noticeably, rinse the cartridge or replace it to restore optimum performance.
- Rinse rather than aggressive cleaning: Rinse with a garden hose to remove surface dirt, pulling debris from the pleats without damaging the media.
- Rotate with other filtration cycles: Pair with other filtration elements or cycles to extend life and maintain water clarity.
- Store dry when not in use: Keep in a clean, dry location to prevent microbial growth between seasons.
