Don't know what size filter to use?
Need to convert a unit of measurement?
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.
