ClearPlus WH5 Series Whole House /
Hydrogen Sulfide Reduction Filter Packages

economical whole house solution for the removal of low levels of iron and hydrogen sulfide at low to moderate flow rates

Our ClearPlus WH5 Series cartridge-based iron filters contain manganese dioxide which reduces iron and hydrogen sulfide (and manganese under the right conditions) through an oxidation / filtration process, thereby substantially improving water clarity, taste, and odor. At the same time, it protects your plumbing system (including your toilets, bath tubs and showers, and appliances such as clothes washers and dishwashers) from unsightly staining. It uses no chemicals, therefore, it adds no harmful chemicals to the water, making it completely safe for drinking water applications. WH5 Series iron and hydrogen sulfide filters are extremely economical for the removal of low contaminant levels at low to moderate flow rates, making them a popular choice for small homes, cabins, recreational properties, and other low flow rate point-of-entry applications.

Soluble iron (ferrous) and manganese are oxidized and precipitated by contact with higher oxides of manganese on the media 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.

Applications & Suitability:

This system should be employed as a whole house application where low ferrous (dissolved) iron and/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 the 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). Not recommended where pH level is less than 7.0 without prior pH correction.For pH levels ranging from 6.5 to 6.9, we strongly recommend the WH6 - KDF85 media cartridge iron filter or our Iron Rival Series of Backwashable Iron Filters.

Suitable reduction of low levels of manganese can often be achieved where the pH level is greater than 8.0 and less than 8.5, and where the manganese level is a minimum of 5x higher than the iron level. For most manganese removal applications, we recommend our Iron Rival Series of Backwashable Iron Filters with Filox media.

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.

Which contaminant 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)

Approximate Life of Filter Cartridge:

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

Estimated Life of WH5 Iron filter Cartridge:
Iron Equivalent Level in Water	Total Gallons Water Used	250 GPD (946 LPD) (four people)	125 GPD (473 LPD) (two people)	75 GPD (284 LPD) (one person)
5 ppm	16,000 gal (60,570 L)	64 days	128 days	256 days
4 ppm	20,000 gal (75,710 L)	80 days	160 days	320 days
3 ppm	26,000 gal (98,420 L)	104 days	208 days	416 days
2 ppm	40,000 gal (151,420 L)	160 days	320 days	640 days
1 ppm	80,000 gal (302,830 L)	320 days	640 days	1280 days
0.5 ppm	160,000 gal (605,670 L)	640 days	1280 days	+2,000 days

*Test results provided by cartridge manufacturer (for WH5B+ model with carbon post-filter). Estimated life assumes that filter is never clogged by sediment thereby reducing flow performance substantially.

ClearPlus WH5 Series Iron / Hydrogen Sulfide Filter Packages

We are pleased to offer several WH5 whole house iron /hydrogen sulfide reduction filter packages to suit your individual needs. Each package contains a heavy duty Pentek Big Blue 20 inch filter housing with pressure relief button, a sturdy mounting bracket, at least one of our iron / hydrogen sulfide reduction filter cartridges, and a handy spanner wrench that makes filter changes as simple as possible. The filter cartridge should be replaced as required and in accordance with the manufacturer's specifications for optimal performance (generally every 4-9 months depending on contamination level and the amount of water your household consumes - see chart above to determine the estimated cartridge life for your application). To maximize the life and effectiveness of our WH5 packages, we recommend that you use a sediment pre-filter rated at 10 microns or smaller to reduce sediment and particles that could pre-maturely clog your more expensive iron filter. Some of our Packages include sediment pre-filtration. Alternatively, you can select a suitable sediment pre-filter from our popular list of cartridge-based sediment pre-filters.

The WH5B+ is recommended in water with elevated organics to improve iron removal performance.

ClearPlus WH5 Series Iron 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 believe it. It's true. - D. King
