If your home's water supply has high iron, manganese or hydrogen sulfide content, you should consider the addition of a whole house iron / hydrogen sulfide reduction filter to your water treatment system. This filter contains manganese greensand which reduces these contaminants through an oxidation / filtration process, thereby substantially improving water clarity, taste, and odor, while at the same time protecting your plumbing system including toilets, bath tubs and showers, and appliances such as clothes washers and dishwashers from unsightly staining. It adds no harmful chemicals to the water, making it completely safe for drinking water applications. Iron and manganese reduction will also prolong the life of a reverse osmosis membrane if you have a point-of-use reverse osmosis system in your home. This filter should be installed on the main cold water line after the pressure tank or water meter. For best results, pre-sediment and post-carbon treatment is recommended.

Application: This system should be employed as a whole house application where low to moderate ferrous (dissolved) iron, manganese, or hydrogen sulfide contamination is known or expected. This filter will also remove ferric iron through mechanical filtration, although a sediment filter may be a more cost effective choice. This filter is most effective where iron contamination level is less than 3 ppm (and no greater than 5 ppm) or the hydrogen sulfide level is less than about 2 ppm. While the filter will indeed remove these contaminants when these levels are exceeded, the filter life expectancy may be shortened significantly, and contaminant removal may be incomplete. If a combination of iron, manganese, and hydrogen sulfide are present, you must consider the "iron equivalent" level when determining if this filter will work effectively in your circumstance (see below). Best contaminant removal rates are achieved where the pH is 7.0 or higher for iron and hydrogen sulfide reduction (8.0 for manganese reduction). This filter is not recommended where pH levels are less than 6.9. For pH levels ranging from 6.5 to 6.9, we strongly recommend the WH6 - KDF85 media iron filter. The WH6 is also recommended for manganese reduction where pH is less than 8.0.

The life of the filter depends on the contamination level ("iron equivalent") and amount of water consumed on a daily basis. You can get a good idea of how long a filter will last in your case by using the chart below.

"Iron Equivalent" is calculated as follows: (Iron level) + (2 x Manganese level) + (3 x Hydrogen sulfide level)

If your level of Hydrogen sulfide is unknown (it is hard to accurately test for) and you have a noticeable "rotten egg" odor, assume a Hydrogen sulfide level of 0.5 ppm. If the rotten egg odor is severe, assume a level of 1.0 ppm.

Example: Test results are 0.8 ppm iron, 0.2 ppm manganese, and you have a rotten egg smell in your water.

        Iron Equivalent = (0.8) + ( 2 x 0.2) + (3 x 0.5) = 2.7

What types of contaminants are you dealing with?
Problem Likely Cause
rusty red or brown staining of fixtures or laundry and/or your water has a metallic taste excess iron
black staining of fixtures or laundry excess manganese
rotten egg smell from water Hydrogen sulfide (H2S)

How it Works: Soluble iron (ferrous) and manganese are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. The precipitates are then filtered. Ferric iron is removed by mechanical filtration.

Recommended Pre-filter: While not essential, the installation of a sediment pre-filter in advance of the WH5 iron / hydrogen sulfide reduction filter system will extend the life of the iron reduction cartridge by preventing sediments and oxidized iron particles (ferric iron) from clogging the filter before its capacity is reached. Our WH1, WH1-HF,WH1B+, or WH1B+-HF whole house sediment filter packages are excellent choices as a pre-filter.

Customer Testimonials:

I [just wanted] to let you know we purchased filters from you when we moved again into a house with well water and couldn't stand the rotten egg smell. Your filters worked miracles with that & I thank you for such an awesome product! - Paula Kennedy

At our old house, we used an expensive iron filter system. We recently moved into a new home and found that our well once again had high iron levels. I was skeptical to try your product since it cost so much less than most other systems on the market. I am sure glad I did! Not only has it saved me a great deal of money and maintenance hassle, it really does work! Forgive me for being so surprised, but I am truly impressed. Thank you! - Jason Harris

We had a very embarrassing problem with a rotten egg odor in our water because of hydrogen sulphide. It smelled like a sewer. My wife and I were embarrassed to have friends and family over to our brand new house for fear that they would turn on a faucet and catch the stench of our water. We installed your WH5 filter system about 4 months ago and wow! What a difference! The smell was completely eliminated from the second we installed the filter and our water even tastes better too. - Bud Hardesty

I would just like to thank you for your recommendation of the iron filter for my iron and sulfide problem. As you may recall I previously had tried to treat the odor problem of my water with carbon filters at the recommendation of a water specialist in my town. While the carbon filters did reduce the odor somewhat, they would only last a few days and then the odor would return. They did not improve the iron stains on my tub at all. The replacement carbon filters were expensive since they needed to be changed so often. I have now been using your unit for just over 4 months and I am still using the original filter! Best of all, not only is the smell gone but the iron stains are gone too. - Tracy Goldman

The iron filter works very well, what a difference in my water, many thanks to your company. - Gradimir (received by email)

Several years ago you helped us select an iron filter for our cottage on the Michigan shores of Lake Huron. We still have "crock" wells... very primitive, and we LOVE our iron filter. It is the envy of the neighborhood. We use more than one filter per season and this is a part time residence, so you see we truly have an iron problem. Without the filter, our water is the color of iced tea and the shower curtain was completely orange and ruined after only one shower! Now we enjoy a clean toilet bowl, clear dish water, and pleasant showers. THANKS!!! - D. Trubiro)

I recently bought and installed your WH5B Iron/ Hydrogn Sulfide filter, with sediment prefilter, on the water supply at my beach house at Edisto Island, SC. We are on a community water system here, and our water had recently gone from being just unpleasant, to being absolutely awful. The smell and the taste were unbearable, and the color was iron (rust) orange. Anything white that we washed came out this same orange color. Installing your water filter unit has completely change the quality of our water. The odor, bad taste, and rust color are all gone. White cloths going into the washer, actually come out of the washer white. AND, we can now actually make coffee with the community water instead of the bottled water we were using. In addition to getting the improved water quality, I was very surprised, and pleased to see how small the pressure drop across the filter was. Your technical data said it would only be a couple of psi, but I didn't delieve it. It's true. - D. King)
