How do I Remove Ferric Iron from My Well Water?

Sediment filters 
A sub-micron rated sediment filter is capable of removing the iron precipitate that has emerged from the water. Sediment filters allow water to flow freely through them while preventing solid particulate matter from entering the household plumbing. Sediment filters are exceptional at preventing dirt, debris, and cloudiness from polluting your home’s water. Make sure your sediment filter has a small enough micron rating to adequately capture the iron. Many well-owners prefer natural cotton stringwound sediment filters to capture and remove the ferric iron in their well water supply. This solution is ideal for those with low levels of iron, all of which is in ferric form. A sediment filter alone will not solve your stained toilets and metallic tasting water if your well has ferrous iron in addition to the ferric iron.
