Filbur FC-0312 Spa and Pool Replacement Filter Cartridge for Artesian Spas Durable OEM Quality

Introducing the Filbur FC-0312 Spa/Pool Replacement Filter Cartridge—a value-forward, OEM-grade option designed to keep Artesian Spas and compatible spa/pool systems running at their best. Built to last, it delivers dependable filtration, easier maintenance, and lasting water clarity in challenging environments.

What makes the FC-0312 stand apart

• OEM-grade construction: Filbur’s heritage as a leading USA filter manufacturer translates into a cartridge designed to fit Artesian Spas bottom-mount housings with confidence and reliability.
• Precise dimensions for a perfect fit: Bottom dimension 2-3/8" outside diameter, length 7", top diameter 1-7/8" with an open top. Built for 2-3/8" OD housings and bottom male pipe thread (MPT) connections, ensuring straightforward installation.
• 6 sq ft of premium filtration media: 3 oz of durable polyester media delivers strong debris loading and steady water flow, helping you achieve clearer water with fewer cleanings.
• Reinforced center cores: Absolutely the strongest extrusion-style PVC center cores provide even stress distribution and reduce the risk of cartridge collapse under heavy debris loading.
• Wider, break-resistant bands: Keep pleats evenly spaced, minimize flutter from turbulence, and maintain optimum flow across the life of the cartridge.
• Antimicrobial, reinforced end caps: End caps treated to repel odor-causing bacteria and mold, reinforced for strength and durability in salt and high-chlorine environments.
• Integrated fittings in end caps: Molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can reduce flow.
• Sharp pleat folds for deeper filtration: Innovative pleat design minimizes bridging, allowing dirt to penetrate deeper into the media for enhanced filtration and easier cleaning.
• Easy reordering: Embossed part numbers on the cartridge streamline identification and replacement when it’s time to refresh your filter inventory.

Why this cartridge matters for your spa or pool

The FC-0312 is engineered to perform in real-world spa and pool scenarios—especially environments with saltwater and heavy chlorine exposure. The combination of a robust center core, antimicrobial end caps, and high-quality polyester media translates into:

• Longer intervals between cleanings due to increased debris loading and improved flow.
• Consistent water clarity as dirt is trapped effectively within the pleats, reducing cloudiness and odors.
• Durable operation in salt and chemically aggressive water, extending filter life and protecting your equipment.

Ideal use cases and care tips

• Best suited for residential Artesian Spas and other spa/pool setups that use the FC-0312 form factor (2-3/8" OD, 7" long, bottom MPT, open top).
• Rinse the cartridge weekly with a garden hose to remove loose debris; periodically soak in a mild detergent solution to restore pliability and restore pleat openness.
• Replace when flow declines noticeably, cleaning becomes ineffective, or after the manufacturer’s recommended service interval to maintain optimal filtration performance.

Choose the Filbur FC-0312 Spa/Pool Replacement Filter Cartridge for a dependable, high-performing filtration solution that’s built to last in salt and chlorine-rich environments, specifically designed for Artesian Spas, and designed to keep your water sparkling clear with less maintenance.
