Pentair Pentek S1-BB Big Blue Sediment Water Filter, 10-Inch, Whole House, 20 Micron

Pentair Pentek S1 Series Cartridges are designed for general water filtration purposes, manufactured from a pleated cellulose media. The media is pleated around a polypropylene core for added strength, with the pleated endcaps of the standard cartridges immersed in a thermosetting vinyl plastisol. The Big Blue cartridges feature a molded endcap with gaskets, and the pleated ends are sealed to the endcap using a thermoplastic adhesive. The overlap seam is sonically welded to reduce bypass, improving filtration efficiency.

These S1 Series Cartridges are economically priced and highly effective at reducing sediment particles down to 20 microns in size. By removing dirt, sand, silt, and particles, they help keep your water clean and protect your appliances.

The cartridges are designed to fit all 10" Pentair Pentek Big Blue or other heavy-duty housings, and can replace any 10" x 4.5" sediment filter cartridge. The pleated media design around the polypropylene core maximizes dirt-holding capacity and provides added strength, making it a recommended solution for chlorinated water supplies.

In summary, the Pentair Pentek S1 Series Cartridges offer an economical and highly effective water filtration solution, featuring a pleated media design, molded endcaps, and a sonically welded overlap seam to ensure efficient sediment removal and protect your water-using appliances.
