Pentair 160352 Posi-Clear RP 150 Sq. ft. Cartridge Filter

The Posi-Clear RP Cartridge Filter features a fiberglass-reinforced, chemical-resistant, polypropylene tank with no-tool servicing for easier cleaning. It also features a side-entry port, which provides nearly 50% more efficiency than any other single-cartridge filter available. Inside, it has increased cartridge surface consistency to block and trap particles as small as 20 microns. The result is picture-perfect pool water and lower energy use.
