Aquaphor RO101 K5 K2 Set of Replacement Filters for Reverse Osmosis Water Filtration System

Keep a reverse osmosis filtration system running smoothly with this set of K2 and K5 Replacement Water Filters. The K5 uses 100% polypropylene media and is used for general clarification and pre filtration. It retains solid particles such as sand and rust measuring five microns or larger. These reverse osmosis replacement filters provide high particle retention, high dirt holding capacity and low-pressure drop. This protects further stages of filtration and extends life of home appliances. The K2 water filter cartridge completes the second stage of the process, comprising preparation, membrane separation and enrichment.  It uses sorption treatment and purification, retaining pollutants as small as three microns. Carbon-Fiber-Block with Aqualen Ion-Exchange Fiber reduces organic impurities and chlorine in water and reduces suspended and sediment particles matter three microns or larger in the incoming water. Aqualen ion-exchange fiber with modified selective chelate groups completely removes heavy metals from water and contains silver in active ionic form (Ag+).  This polypropylene sediment filter cartridge set has an ergonomic design, making tool-free installation quick and simple. Replacing both filters as a pair every six months is recommended.
