S1 Series Resin-Impregnated Cellulose Filter Cartridge, Vinyl Plastisol Filter Media, 20 micron, 9-3/4" length

Pentek S1 cartridges are manufactured from a pleated cellulose media and are designed for general water filtration purposes. The media is pleated around a polypropylene core for added strength and the ends are immersed in a thermo-setting vinyl plastisol, forming a unified end cap and gasket. An external netted sheath helps retain uniform pleat spacing in high flow and pulsating flow streams. S1 cartridges are economically priced and highly effective at reducing sediment particles down to 20-microns in size.
