Pentair Pentek 20" Big Blue 1 Micron & 5 Micron Dual-Gradient Density Whole House Sediment Water Filter Cartridge Replacement Bundle

This bundle contains two 20-inch Big Blue compatible water filter cartridges from Pentair's DGD series designed to keep your water clean. The first cartridge filters down to 1 micron, effective at removing dirt, sand, silt, and other particulates. The second cartridge filters down to 5 microns. With their dual-gradient density spun polypropylene construction, these cartridges offer superior chemical resistance and 3 times the dirt holding capacity compared to similar sediment cartridges. The 1 micron and 5 micron ratings allow you to install a two-stage filtration system, with the 1 micron cartridge providing finer particulate filtration after the 5 micron cartridge captures larger contaminants. Their 100% pure polypropylene material ensures no imparted tastes, odors, or water color. Tested and certified to NSF/ANSI Standard 42, these Big Blue compatible cartridges are an ideal choice for whole house filtration needs, protecting appliances and plumbing fixtures.
