Designed as a direct replacement for Filbur FC-0491 in residential spas and pools, this cartridge blends rugged construction with advanced filtration for clearer water and easier maintenance.
Why this FC-0491 replacement stands out
- Reinforced center cores—extruded PVC cores with substantial round holes provide even stress distribution and keep the cartridge from collapsing under heavy debris loading, boosting time between cleanings.
- Antimicrobial, reinforced end caps—end caps resist odor-causing bacteria and mold, and are built to withstand salt pools and high chlorine environments without deteriorating.

- Premium polyester media—durable, easy to clean, and designed for long service life with efficient filtration performance and sustained water clarity.
- Sharp pleat folds—a unique fiber construction prevents bridging, allowing dirt to penetrate deep into the pleats for improved filtration and easier cleaning.
- End caps with integrated fittings—molded-in fittings simplify installation and removal, eliminating the need for adapters that can impede flow.
- Easy identification and reordering—embossed part numbers help you locate exact replacements quickly, reducing downtime in maintenance routines.
