Engineered for spa and pool filtration, the Filbur FC-3104 Replacement Filter Cartridge delivers dependable clarity and long service life. As a leading OEM filter maker in the USA, Filbur designs cartridges that endure heavy use and resist harsh water chemistry, so you spend less time replacing and more time enjoying clean water.
Key advantages that matter in daily use
-
Reinforced center cores: extruded PVC cores distribute stress evenly and handle high debris loads without collapsing, extending time between cleanings.
-
Premium filter media: durable polyester media traps dirt efficiently while staying cleanable for multiple cleaning cycles, helping water stay clear.
-
Antimicrobial end caps: reinforced end caps include molded-in fittings and antimicrobial treatment that repels odor-causing bacteria and mold, even in salt and chlorine-rich environments.
-
Sharp pleat folds: engineered to prevent bridging; dirt penetrates deeper into the pleats for better flow and easier cleaning.
-
Wider break-resistant bands: keep pleats evenly spaced and resist flutter from housing turbulence, preserving filtration performance.
-
Integrated fittings: end caps with built-in fittings simplify installation and remove the need for PAD adapters that can impede flow.
-
Embossed part numbers: easy to identify and reorder when you’re stocking replacements.

This FC-3104 cartridge is designed for longevity in both saltwater and chlorine environments, making it a versatile choice for hot tubs, spas, and in-ground or above-ground pools. The combination of robust cores, antimicrobial protection, and high-efficiency pleats translates to longer filter life, clearer water, and lower maintenance frequency—even in high-usage settings.

Usage and care tips
- Install in compatible filter housings and ensure end-cap fittings seat firmly to prevent leaks.
- Rinse the cartridge with a gentle spray to remove surface dirt after each use; deeper cleaning with a cartridge cleaner extends life.
- Monitor pressure differential—if you see a notable rise, it’s time to clean or replace the cartridge to maintain optimum flow.
- Store dry when not in use to prevent microbial growth and deformation.
