Iron is one of the most common elements on earth and can be found in almost all natural water supply sources. Learn more about its impact on our drinking water below.
While trace levels of iron are harmless, high iron levels can make water taste metallic, and turn it red, brown, or yellow in color. High iron can also deposit brown, orange or yellow stains on kitchen and bath fixtures, as well as washing machines and clothing.
How the levels of Iron can effect Water Treatment
The most common iron in water supplies is soluble iron. If your water has red or yellow colorization, you probably have iron in your water. If you can see red-brown particles settling at the bottom of your drinking glass, it’s soluble iron. Less common is insoluble iron, or “red water"" iron, which makes water rusty or yellowish in color, and is distinctly unpleasant to drink.

In order to deal with iron in your water, you need to establish the severity of the problem.
The EPA recommends that safe water includes less than 0.3 mg of iron per liter of water. If your water has iron above this level, recommended treatment depends up on the iron level.
For water with up to 3 ppm (parts per million) of iron, you can use an Iron Cartridge Whole House System. This provides three levels of cartridge filtration and is not a major investment.
For water with up to 4 ppm, you can use the Whole House Hardness, Iron and Manganese Filter and 45,000 Grain Capacity Water Softening System by Tier1.
For water over 4 ppm, you can use the Whole House Iron, Manganese and Hydrogen Sulfide Air Induction Oxidization Filter System by Tier1
Another solution for iron removal is KDF filtration.
Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation. KDF uses a chemical process known as redox (oxidation/reduction). This chemical process removes iron, chlorine, mercury, lead, and hydrogen sulfide from water supplies.
The KDF redox process works by exchanging electrons with contaminants, changing them into harmless components. During their reactions, electrons are transferred between molecules and new elements are created.
KDF 55 and KDF 85
The two types of KDF most often used for water filtration are KDF 55 and KDF 85.
KDF-55 Media: reduces chlorine and soluble heavy metals. A KDF-55 filter media can remove over 99% of free chlorine. For chlorine removal in point-of-use applications, KDF media is incorporated into shower filters and into cartridge at the tap. Listed as a microbial device by the EPA for its outstanding bacteria control, KDF is bacteriostatic.
KDF-85 Media: reduces iron and hydrogen sulfide. KDF 85 is efficient at removing iron and hydrogen sulfide. KDF-85 also controls scale, bacteria and algae. Like KDF55 media, KDF85 uses the redox method to remove chlorine, chlorinated hydrocarbons, hydrogen sulfide, iron, and metals like lead, arsenic, aluminum, mercury, and cadmium from water. KDF process media act as catalysts to change soluble ferrous cations into insoluble ferric hydroxide, which is easily removed by regular backwashing. KDF 85 medium removes more than 90% of iron from groundwater supplies.
