Description
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.
Designed to maximize water clarity and minimize maintenance, this cartridge helps you spend less time cleaning and more time enjoying your water. The robust center cores resist sagging under load, while the antimicrobial end caps keep the filter more hygienic over time. With integrated fittings and easy-to-identify part numbers, installation, replacement, and routine servicing become straightforward tasks, not headaches.
Ideal for:- Home spa enthusiasts who want long-lasting filtration without frequent cartridge changes
- Pool owners with saltwater systems or heavy chlorine usage seeking durable, reliable filtration
- Maintenance professionals and property managers needing consistent performance in both residential and light commercial settings
- 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.
