Pentair Posi-Clear RP 100 SqFt Cartridge Filter

The Pentair Posi-Clear RP Cartridge Filter (100 sq ft) is a highly efficient, single-cartridge pool filter designed for superior performance with low maintenance. The filter’s side-entry design optimizes flow for energy efficiency, while the fiberglass-reinforced polypropylene tank provides strength and chemical resistance. Maintenance is made easier thanks to a quick-connect lock ring and a coreless cartridge that can be rinsed without tools.

Key Features

• Side-entry design for nearly 50% greater flow efficiency compared to many single-cartridge filters
