Description
Meet the Filbur FC-3089 Spa/Pool Replacement Filter Cartridge—the reliable, high-performance choice for clean, inviting water in home spas and pools. Built with Filbur’s signature focus on value, this cartridge is engineered to outlast standard replacements, resist harsh water chemistry, and deliver consistent filtration you can feel in every soak or swim.
Why the FC-3089 stands out
- Reinforced center cores deliver even stress distribution and higher debris loading, reducing the risk of collapse under heavy filtration and extending the time between cleanings.
- Premium polyester media provides durable, efficient filtration with longer service life and easier cleaning, keeping water clearer for longer.
- Antimicrobial end caps feature reinforced mesh for added strength and a treatment that repels odor-causing bacteria and mold, while resisting salt pool and high-chlorine wear.
- Wider support bands help keep pleats evenly spaced, prevent flutter from turbulent water, and maintain optimal flow across the cartridge.
- Sharp pleat folds prevent bridging and allow dirt to penetrate deep into the folds for improved filtration efficiency and easier cleaning.
- End caps with integrated fittings remove the need for PAD adapters, simplifying installation and improving flow from the moment it’s installed.
- Embossed part numbers enable quick identification and easy reordering, so you’re never guessing when a replacement is due.
- Extruded PVC center cores are the strongest design choice, with round holes that evenly distribute stress and reduce the risk of cracking or collapse.
Designed for real-world use in spa and pool environments
- Ideal for saltwater and high-chlorine systems where durability matters as much as filtration performance.
- Perfect for homes with heavy debris loads—from leaves and pollen to fine particulates—where longer filter life translates to fewer maintenance sessions.
- Suitable for both in-ground and above-ground setups, delivering consistent flow and reliable water clarity across a range of spa and pool sizes.
What this means for you
