CFS 20" x 4.5" Sediment Filter Cartridge keeps your water clean and protects your home's plumbing and appliances by removing dirt, sand, silt, and other particulates. Designed with dual gradient density, it captures sediment efficiently while maintaining water clarity without affecting taste, odor, or color.

This high-flow pre-filter features a unique design where the filter density increases toward the center, providing superior particulate reduction and up to 3 times the dirt holding capacity of standard 20 inch sediment cartridges. The cartridge is compatible with a wide range of 20x4.5 inch whole house filter housings, including Big Blue systems, and can replace popular models such as DGD-5005-20, Liquatec SDF-45-2005, Tier1 SDF-45-2005, and other comparable polypropylene sediment cartridges.

Installation is quick and simple, ensuring consistent water flow and clean water throughout your home. Manufactured from pure polypropylene and tested to NSF, this dual gradient 20-inch cartridge features a first stage micron rating of 50 and a second stage rating of 5, meeting rigorous standards for sediment filtration and reliability.

The 2-pack provides extended use, helping maintain consistent water quality across your whole house system. For best results, replace the cartridge every 6 months or when water pressure drops or water quality decreases.
