The Hydronix 20" Big Blue Sediment Filter is a high quality equivalent to the Liquatec SDF-45-2001, Pentek DGD-2501-20, Watts FPMB-BB1-20, and many other brands. This 100% polypropylene filter contains graded density that provides higher dirt holding capacity than standard spun polypropylene and string wound cartridges. The 1 MICRON FILTER reduces waterborne contaminants like sand, silt, sediment and rust. The 20" Big Blue Hydronix Filter is resistant to chemicals and constructed with a coreless design.The filter is surfactant free, adhesive free and binder free. The true multi-stage depth filtration of this cartridge is ideal for residential, industrial, commercial and food service applications.

The Hydronix Big Blue Sediment Filter uses 4 separate layers of micron filtration, as the outside-in flow allows the outer layer to trap larger sized particles. Also known as part number SDC-45-2001, this 1 MICRON FILTER is an inexpensive solution to pre-filtration for whole house filtration systems. The Hydronix 20" Water Filter fits any housing systems requiring 20" Big Blue cartridges. For optimum performance, change your filter every 6 months, based on water quality and usage. Be sure to check the size of your filter prior to purchasing. This sediment filter is tested and certified by NSF International under ANSI/NSF Standard 42 for material requirements only.
