Restore Maximum Filtration Performance to Your Clean & Clear Plus 420

When pool water starts losing clarity or filter pressure rises too quickly, worn cartridge filters are often the cause. The Unicel C-7471-4 Cartridge Filter Set is a 4-pack of 105 sq ft replacement cartridges designed specifically to restore full filtration capacity in the Pentair Clean & Clear Plus 420 pool filter.

Replacing all four cartridges at once ensures balanced flow, consistent pressure, and optimal debris capture—helping your pool stay cleaner with fewer cleanings and longer filter cycles.

Engineered for OEM Fit and Reliable Performance

Unicel is a trusted leader in pool filtration, known for producing high-quality replacement cartridges that meet or exceed OEM specifications. The C-7471-4 filters are manufactured with precision dimensions to ensure a proper fit inside the Clean & Clear Plus 420 housing, preventing bypass and uneven filtration.

Each cartridge is built to handle demanding residential and light commercial pool conditions.

Why Replacing the Full Cartridge Set Matters

Mixing old and new cartridges can lead to uneven flow, pressure imbalance, and reduced filtration efficiency. A complete 4-pack replacement restores the filter to like-new performance.

Why it matters:

• Restores full 420 sq ft total filtration area

• Improves water clarity and circulation efficiency

• Reduces pressure spikes caused by clogged media

• Extends the life of the filter tank and pump

Premium Reemay® Filtration Media

Each Unicel C-7471-4 cartridge is constructed using genuine Reemay® polyester filtration fabric, engineered for superior dirt-holding capacity and consistent water flow. The durable pleat structure resists collapse and tearing, even under high-flow conditions.

This results in longer cleaning intervals, improved clarity, and reliable filtration throughout the swim season.
