• IDEAL HIGH-FLOW PRE-FILTER - Dual-gradient density construction increases filter density from the outer surface to the core, delivering up to 3X the dirt-holding capacity of similar-size sediment cartridges and 233% greater effective filter depth.
• TESTED AND CERTIFIED TO NSF/ANSI 42 - Independently tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Manufactured from 100% pure polypropylene for purity and broad chemical compatibility.
• FITS ALL 20-INCH BIG BLUE HOUSINGS - Drops into any 20" Big Blue or other heavy-duty housing and replaces any 20" x 4.5" sediment cartridge, with a low pressure drop under 1 psi at 20 gpm for strong whole-house flow.
• REPLACE EVERY 6 MONTHS - Change the cartridge about every six months, or sooner when you notice a drop in water pressure or water quality. Nominal 5 micron rating suits residential, rural, municipal and commercial water.

The Pentair Pentek DGD-5005-20 is a 20-inch dual-gradient density sediment cartridge for whole-house, point-of-entry filtration. Spun from 100% pure polypropylene, it reduces dirt, sand, silt and rust, adds no taste, odor or color to your water, and offers broad chemical compatibility.

Its dual-gradient design packs the fibers more tightly from the outer surface toward the core, raising effective filter depth to a full 233% and delivering up to three times the dirt-holding capacity of similar-size cartridges, with a low pressure drop under 1 psi at 20 gpm.

Measuring 20" x 4.5", it fits all 20-inch Big Blue and other heavy-duty housings and replaces any 20" x 4.5" sediment cartridge. It carries a nominal 5 micron rating, handles temperatures to 145°F, and is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Replace about every 6 months, or sooner when you notice reduced flow or water quality.
