This is a 2.5 inch by twenty inch (20") sediment filter. Used in small commercial RO systems or where more flow than the typical small 10" filter can provide. These filters should fit all slimline 20" housings. They will fit Big Blue filter housing by twenty inch as well. Available in 5 or 10 micron. The standard 5 micron PPY polyspun is for normal city water. The 10 micron string wound sediment filter is great for well water or bad city water.
