Iron filters are great for reducing iron and manganese levels in your water. There are four different kinds of filters with manganese greensand being the most common and used 98% of the time. This media, combined with a regenerate of potassium permanganate oxidizes iron into a form that can be trapped by the filter bed and washed away.
A moderate level of maintenance will ensure that your iron filter is always working at its best level of efficiency.
*With a meter-initiated head on your iron filter, you can save up to 50% of potassium permanganate costs. At about $150 it pays for itself after 2 years.
