See the many layers of a Westinghouse Water Refiner. Each serves a specific purpose.
High Microporosity Granular Activated Carbon
High Microporosity Granular Activated Carbon filtration media has a very large surface area for superb adsorption of volatile organic compounds, trihalomethanes, and chlorine.
BlackCat® Ion Exchange Media
BlackCat® ion exchange media is a proprietary engineered synthetic resin that is made up of small beads that are electrically charged to attract positively charged ions from your water. These beads continuously attract hardness ions such as calcium and magnesium from your water and exchanges sodium ions in return. This stage removes undesirable hardness ions and reduces clear water iron. Hardness ions interfere with the action of soaps, build up lime scale deposits which can foul plumbing, shorten the life of water using appliances, etch glass, stemware and flatware, stain fixtures and faucets and accelerate galvanic corrosion.
Bacteriostat 55 is a patented media that controls scale, bacteria, fungi and algae. It is capable of removing up to 99% of water-soluble lead, mercury, nickel, chromium, and other dissolved metals. The science behind this patented media is impressive. It creates an electrochemical reaction solution, known as redox, which transfers electrons between molecules, thus creating new molecules. Some harmful contaminants are changed into harmless components. Free chlorine, for instance, is changed into benign, water-soluble chloride.
Garnet Filtration Media
Garnet Filtration Media is a water clarifier and 20 micron sediment filter. It also enhances the surface area of the lower distributor reducing water channeling as water flows downward through the refiner.
