The main function of sediment filter is to remove large and fine particles from a drinking water, such as sand, dirt, silt, and rust particles. These filters have graded density layers, meaning the outer layers are more porous, catching larger particles, while the inner layers are a finer micron catching smaller particles. Each cartridge is individually shrink-wrapped. Features:Standard Universal Filter Cartridge: 5 Micron big blue replacement sediment water filter cartridge, 20″ Length by 4.5″ Outside Diameter.
