Iron Filters Aren't Just for Iron: What Else Can They Remove?

When you think of an iron filter, its primary purpose is usually obvious: to remove iron from your water supply. But, what if you're dealing with more than just iron? Can iron filters tackle other contaminants as well? The answer is yes and this article will show you why.

What Do Iron Filters Actually Do?

At their core, iron filters are designed to oxidize and filter out iron from water. They typically use a two-stage process that involves oxidation and filtration. During the oxidation stage, a pocket of air at the top of the filter oxidizes the iron, sulfur, and manganese, transforming them into particles. In the filtration stage, these particles pass through a media bed—often composed of Katalox Light or other filtration media—that traps and removes them from the water.

Iron Filters: Beyond Iron Removal

Many modern iron filters are capable of multi-contaminant removal. Advanced filtration media, such as Katalox Light, enables the filter to remove not only iron but also manganese, sulfur, and even heavy metals like arsenic and lead. This is an upgrade from traditional media like Sand and Greensand, which are usually less versatile.
