The Culligan S1A-D Sediment Water Filter Cartridge 

This filter cartridge reduces sand, sediment, silt, rust particles, and scale particles. The Culligan S1 filters have pleated walls for dirt-holding capacity. The Culligan S-1 water filter media is pleated around a polypropylene core for added strength and the ends are immersed in a thermo-setting vinyl plastisol. The Culligan S1 water filter cartridge has an external netted sheath that helps retain uniform pleat spacing in high flow and pulsating flow streams. The overlap seam is sonically welded to reduce bypass, improving filtration efficiency.
