They reduce staining by retaining these metals in solution and preventing oxidation. This method is only effective for levels of iron and manganese less than about 1 ppm and if the water will not be heated. Heating releases the metals and allows oxidation to occur.

Solution 1: For water with up to 3 ppm (parts per million) of iron and/or if you are trying to avoid as much upfront cost. Solution 1 includes 3 stages of cartridge filtration. Use the Iron Reduction Whole House System available below. Solution 2: For water with up to 30 ppm (parts per million) of iron use the TIER1-WH-IRN-MG-SLFR-BW-1054 system.

When the water’s pH rises above 7.2 to 7.3, the softener’s ability to grab iron from the water becomes increasingly limited.
Iron is usually present in all water, although, according to the Wisconsin Department of Natural Resources, rarely in levels that exceed 10 milligrams per liter (mg/1) or 10 parts per million (ppm). The current recommended levels of iron in well water varies slightly by state, but they range between .2 and 1 mg/l. When iron exceeds these levels, the taste and color of the water can be affected, giving water a metallic flavor or odor and a red, brown or yellow cast that can stain dishes ral water supply, including well water.
However, as little as 0.3 mg/l can cause water to turn a reddish brown color. Iron is mainly present in water in two forms: either the soluble ferrous iron or the insoluble ferric iron.

Although iron is present in our water, it is seldom found at concentrations greater than 10 milligrams per liter (mg/l) or parts per million (ppm). Health and Water Quality Iron is not considered hazardous to health. In fact, iron is essential for good health because it transports oxygen in your blood. The amount varies strongly, and is different in the Atlantic and the Pacific Ocean.
