What is a sediment water filter cartridge? It’s usually placed as the first stage of the water filtration system to remove rust, iron, sand, silt and particulates from water. As the first line of defense in the filtration system. It’s a best choice for removing fine sediment from well water / hard water / city water / municipal water / drinking water, etc. What is a micron rating? The unwanted particles found in water are measured in microns. For example, a filter with a micron rating of 5 will filter out contaminants of 5 micron or larger. Our filter with 99% efficiency rating removes 99% of the particles at all above the 5 micron size. How to choose the right size? if you find a lower micron filter being clogged quickly and your water supply loses pressure in the house, we recommended to choose a higher micron rating filter. Multi-Layer Design: 100% melt-blown thin fiber, Multi-layered Pure Polypropylene. Graded porosity design removes particles in sequence by size – larger particles by the more open outer layers and smaller particles by the tighter inner layers. It increases dirt-holding capacity. Longer service lifespan because of higher dirt-holding capacity. Standard Dimension:10 inches x 2.5 inches sediment filter cartridge. The Filtration micron is 1 Micron / 5 Micron.
