Pentek S1-BB Sediment Water Filters (9.75-inch x 4.5-inch)

The Pentek S1-BB water filters reduce sand, sediment, silt, rust particles, and scale particles. The Pentek S1-BB filters have pleated walls for dirt-holding capacity. The Pentek S1-BB water filter media is pleated around a polypropylene core for added strength and the ends are immersed in a thermosetting vinyl plastisol. The Pentek S1-BB has gone through a manufacturing change and no longer has an external netted sheath.
