Filbur FC-2976 Spa/Pool Replacement Filter Cartridge is built to outlast and outperform in both home spas and everyday pool filtration. As a trusted name in OEM filters across the USA, Filbur blends rugged construction with clever design to deliver clearer water and less maintenance time.

• Strong, reinforced center cores: Extruded PVC center cores distribute stress evenly and handle heavy debris loading, helping prevent cartridge collapse and extending time between cleanings.
• Premium polyester media: Durable, cleanable filtration that maintains water clarity and supports longer cartridge life in chlorine or salt environments.
• Antimicrobial end caps: Reinforced end caps treated to repel odor-causing bacteria and mold, with special formulation to resist deterioration from salt pools and high chlorine levels.
• Wider support bands: Increased break-resistance and steadier pleat spacing for optimum flow, reducing pleat flutter caused by turbulence in the housing.
• Sharp pleat folds: Unique synthetic fiber construction prevents bridging, allowing dirt to penetrate deep into the pleats for higher filtration efficiency and easier cleaning.
• End caps with integrated fittings: Molded-in fittings enable quick installation and removal, eliminating the need for PAD adapters that can impede flow.
• Embossed part numbers: Easy identification and re-ordering so you always have the right replacement on hand.

Practical tips for maximizing performance

• Rinse the cartridge with a gentle, low-to-moderate flow to remove surface debris and restore flow without damaging the pleats.
• Avoid harsh chemical shock or excessive high-pressure cleaning that could wear the media or end caps.
• Monitor water pressure and replace when differential pressure rises or when flow noticeably declines, even if visually clean.
• Store in a dry, shaded area when not in use to preserve the integrity of the media and end caps.
