Dirt/Rust & Sediment Filters
Medium Sediment Filtration – 20 Micron Particles

Problem
Particulates in your cold water.

Solution
A Keystone 20 micron sediment removal filter.

A single 20 micron particle of sediment cannot be seen by the naked eye. In large numbers, they become noticeable and objectionable.

Keystone sediment filters utilize a pleated cartridge to provide a large amount of filtration surface area and greater dirt holding capacity. In water and water-like liquids, dirt is trapped on the outside surfaces of the filter cartridge. The large surface area of a pleated cartridge greatly increases the life of the filter and allows our filters to perform in the same manner as the hard working, long lasting air and oil filters in your car. Independent tests prove that a pleated cartridge will last 2 to 3 times longer than other types of sediment cartridges.

A 20 micron filter cartridge provides adequate filtration for most situations.
