These filters use a media to remove iron without the need for additional chemicals. They effectively reduce iron levels from the water and improve water clarity, helping to avoid staining and build-up.

Oxidizing filters convert dissolved iron into a solid form that can be easily filtered out. This system effectively handles high iron content and is ideal for water sources with significant iron issues.

Catalytic filters use a specialized media to promote the oxidation of iron, enhancing iron removal efficiency. This type of filter is highly effective in treating water with moderate to high levels of iron.
