APC APCC7221 Spa Filter (75 Sq Ft) | Fits Unicel & Filbur

High-Performance Clean Water for Your Spa

The APC APCC7221 is a premium 75 sq. ft. replacement filter designed for hot tubs and spas requiring a narrow, long-body cartridge. Engineered with high-density polyester media, this filter captures fine debris, body oils, and minerals to keep your water crystal clear and your pump running efficiently.

🔄 Perfect Fit & Compatibility

This cartridge is a direct, drop-in replacement for the following common parts:

• Unicel: C-4975
• Filbur: FC-2395
• OEM Part #: 17501
• Common Brands: Fits systems from Rainbow, Pentair, Hydro Pool, and more.

✨ Key Benefits

• Maximum Filtration Surface: 75 sq. ft. of premium media provides a massive surface area to trap contaminants without restricting water flow.
• Long-Body Design: Specifically molded for slim/narrow filter housings.
• Built to Last: Features reinforced end caps and a high-flow core to prevent "collapsing" under pressure.
• Easy Maintenance: Designed for quick removal and deep cleaning to extend the life of the cartridge.

📐 Technical Specifications

• Outside Diameter: 4 15/16"
• Length: 20 1/8"
• Top/Bottom: Open (2 1/8" ID)
• Filter Media: 3oz Premium Polyester

💡 PRO TIP: Because the APCC7221 is long and narrow, debris can get trapped deep in the pleats. When cleaning, stand the filter upright and spray your hose from the top down at a 45-degree angle. This "flushes" the dirt out rather than pushing it further into the media.
