Description
Meet the Filbur FC-2965 Spa/Pool Replacement Filter Cartridge—the durable, high-performance filtrator built to keep spas and pools sparkling with less maintenance. Filbur is focused on value, crafting cartridges that last longer and deliver reliable filtration, and they’re recognized as a leading OEM filter manufacturer in the USA.
- Reinforced center cores—extruded PVC center cores with round holes distribute stress evenly, preventing collapse under heavy debris loading and boosting overall debris capacity for longer life between cleanings.
- Premium filter media—a durable, efficient polyester media that maintains water clarity and supports sustained filtration performance, even in demanding spa and pool environments.
- Antimicrobial end caps—reinforced for added strength and treated to repel odor-causing bacteria and mold, helping keep your filtration system fresher between cleanings and resisting deterioration from salt pools and high chlorine.
- Wider, break-resistant bands—keep pleats evenly spaced, reduce flutter from turbulence, and maintain optimum flow for consistent filtration.
- Sharp pleat folds—a unique synthetic fiber construction that minimizes bridging, allowing dirt to penetrate deep into the pleats for improved flow and easier cleaning.
- End caps with integrated fittings—molded-in fittings simplify installation and removal, eliminating the need for PAD adapters that can impede flow.
- Emboldened identification—embossed part numbers make reordering quick and straightforward, so you’ll spend less time shopping and more time enjoying clean water.
The FC-2965 is engineered to handle the demands of both saltwater and high-chlorine environments, making it a reliable choice for households upgrading spa or pool filtration. The combination of a reinforced center core, antimicrobial end caps, and precision-pleat construction means you’ll experience better debris loading, reduced risk of pleat flutter, and steadier water clarity over time. This isn't just a replacement cartridge—it's a filtration upgrade designed to extend system life and minimize maintenance headaches.
