Product Information
Pentek R50
Watts WPC50-975

The Pentek R50 Replacement Pleated Polyester Filter replacement water filter cartridge is designed to capture coarse sand, rust, and scale particles. The high dirt-holding capacity is ideal for use with well-water. Manufactured around a pleated polypropylene core with ends immersed in a thermo-setting vinyl plastisol, the filter easily meets the demands of modern filtration systems. In addition, each of the filter's pleats are arranged and fused along with the core and endcaps resulting in a unified design. The overlap seam is sonically welded to reduce internal bypass improving filtration efficiency.
