Generally, we recommend an iron filter to remove iron, but in certain cases, a water softener will do the trick, too. That is if your water’s pH is around 7.0, and if your iron is rusted (ferric) and not clear (ferrous) you can indeed use a water softener for iron removal. For such applications, fine mesh resin is the more effective choice.
This is because fine mesh resin is smaller and packed more tightly than regular resin, and has a larger surface area to which iron can attach. Under the right conditions, fine mesh resin can filter up to about 10 ppm of iron from water, though 5 ppm is generally a more realistic threshold.
While we do recommend fine mesh resin for your softener if you intend to remove iron, we also want to note that there are some drawbacks to using fine mesh resin.
Of course, this can happen with standard resin as well, but it will occur more frequently with fine mesh resin due to it being more tightly packed. Note that such fouling will also reduce the effectiveness of your softener because the iron in the resin will limit cation exchange (the process by which softeners remove calcium and magnesium ions and replace them with sodium ions).
