Iron can cause a metallic taste in water; orange/brown stains in sinks, toilets, tubs, and other plumbing fixtures; and damage to pipes and hot water heaters. The FilmTec membrane does not remove iron, and it is recommended that you do not use the membrane with water that is greater than 2 parts per million of iron. To reduce the iron in your water, you should either install a water softener or purchase an iron-reduction filter. Ametek makes a special iron-reduction filter for this purpose. The price is $93 for the filter plus $20 for the housing, plus shipping. (No handling fee.) The filter is 4-5/8" in diameter and 20" long, and the housing is slightly larger. If you are using it for all the water in your house, it will last 3 to 6 months for a family of four. On the other hand, if you are only using if as a pre-filter for your Reverse Osmosis system, it will last much longer.
Here are some companies that claim to have treatment solutions for water which is high in Arsenic, Hydrogen Sulfide, Iron, Manganese, Nickel, Copper, Vanadium, and/or Zinc. Home Reverse Osmosis has not looked into the quality of these companies or the products they offer and is not recommending any companies or their products. We are merely providing the names of these companies as a convenience to our customers, and our customers agree to use them at their own risk.
