CFS 20" x 4.5" Big Blue Sediment Water Filter Cartridge delivers reliable whole house filtration designed to improve water clarity and quality. Constructed with melt-blown polypropylene, this filter effectively captures fine particles such as sand, silt, dirt, and rust down to 5 microns. The gradient density design ensures excellent sediment removal while maintaining high flow rates, helping to extend the service life of appliances, plumbing fixtures, and additional filtration stages. Built for standard 20-inch Big Blue-style housings, this high-capacity cartridge supports consistent water pressure and flow in residential and light commercial applications. It serves as an ideal first-stage filter to reduce sediment before carbon, reverse osmosis, or softening systems. By minimizing the amount of particulate matter entering the water supply, it enhances overall system efficiency and helps protect downstream filters and equipment. The durable polypropylene material resists degradation from chemicals and prevents microbial growth, ensuring dependable performance over time. Installation is simple—place the cartridge into the housing, secure the cap, and enjoy improved water quality throughout your home. Filter replacement is generally recommended every 3 to 6 months, depending on usage and water conditions.
