Pentek Big Blue S1 10″, 20 Micron Nominal Pleated Cellulose Filter

This is a Pentek Big Blue S1 10″, 20 micron nominal pleated cellulose filter. Pentair Pentek S1 Series cartridges are manufactured from pleated cellulose media and are designed for general water filtration. The media is pleated around a polypropylene core for added strength, and the ends are immersed in a thermo-setting vinyl plastisol. Embedding and sealing each end of the pleat in this fashion fuses the three components, forming a unified end cap and gasket. The overlap seam is sonically welded to reduce bypass, improving filtration efficiency. S1 Series Cartridges are economically priced and highly effective at reducing sediment particles down to 20 microns in size.
