20" x 4.5" Whole House Big Blue Water Filter Cartridges Sediment 1micron

The main function of grooved 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. Grooved surface provides more contact area to offer more water flow and more capacity to hold dirt and particles.  For same quality of water, grooved sediment filter generate more contaminant holding capacity and longer life expectancy.
