Pentek WS-20 is a 20-inch X 2.5-inch cartridge that fits into a variety of industry-standard filter housings including American Plumber, Culligan, and US Filter system. The Pentek WS-20 uses a sodium bed, made from cation resin beads, to reduce hardness, minerals and scale deposits in the water. This water softening filter has a capacity of approximately 1,500 grains; this means that the filter can remove approximately 0.025 parts of dissolved solids per gallon of water. The filter cartridge also integrates polypropylene pre and post-filter which can effectively remove traces of sediment, rust, dirt, sand, and other particulate matter. However, the Pentek WS-20 will not remove fluoride from your water.
This water softening filter is recommended initially for use in low flow rate point-of-use (POU) applications in both commercial and residential settings. All elements of the filter have stayed manufactured according to strict FDA standards, so no solvents were used in the production or joining process. This makes the Pentek WS-20 ideal for use in drinking water systems such as dispensers and coffee machines. However, if the water softening filter is being used in an environment where the water has not been verified for microbiological purity, then an additional carbon filter should be used.
The Pentek WS-20 has an estimated shelf life of 3-6 months depending on usage and water quality. Earlier replacement may be required if a sudden drop in flow rate is indicated.
