<h4 class="dechead">On One Hand: Iron Filters are Mandatory for Some
In their 1989 article "Iron Toxicity," metal toxicity experts Dr. Paul C. Ecks and Dr. Larry Wilson point out that three to six people per 1,000 suffer from hemochromatosis, a genetic disorder in which the body cannot break down and eliminate iron. As a result, too much is absorbed into the body. This can cause abdominal pain, skin darkening, weakness and even death.
On the Other: Dissolved Iron is Mostly Just a Nuisance
Given the rarity of hemochromatosis, per Ecks and Wilson, iron-rich water doesn't pose a health hazard for most of us. However, it can cause taste issues, discoloration and staining. If iron deposits accumulate in pipelines, water softeners, water heaters and similar equipment, it can cause damage and increased energy costs.
Bottom Line
Hemochromatosis sufferers should install an iron filter just to be on the safe side, whatever the iron content of their water. To avoid deposits, staining, or other aesthetic issues, an iron filter is advisable if the groundwater has a high iron content, or if iron water pipes are used in municipal plumbing.
