WSP Whole House Iron & Sulfur Filter - All-In-One, Catalytic MnO2, C-Series

Within the first week of installing this system, you'll notice your sinks, tubs, and toilets no longer show orange-brown staining and the water's sulfur smell is much weaker. The usual scrubbing and airing out to fight the rotten-egg odor becomes a thing of the past.

What’s Behind the Stains and Smell You Live With

The orange-brown rings in your toilet tank and bathroom fixtures come from iron in your water. That rusty color is iron particles settling and oxidizing — basically, the iron reacts with oxygen in the air or water and forms the stains you see. The sulfur smell, like rotten eggs, is caused by hydrogen sulfide gas. It’s that gas that bubbles up when you run hot water, creating a noticeable odor that lingers in your shower and kitchen sink. If you test your water for these specifically, you’ll see iron and hydrogen sulfide levels confirm the source of the problem.

How This Control Head Makes the System Work Smarter

The control on top counts how much water you actually use, rather than just running on a timer. That means it regenerates or backwashes only when needed, saving water and salt. It uses an air-draw method, pulling in a pocket of air to help oxidize iron and sulfur without chemicals. The air pocket lifts and rinses the filter bed automatically, keeping it clean and efficient for as long as possible. You can even connect to the control from your phone to monitor and adjust settings conveniently.

The Special Media That Tackles Iron and Sulfur

Inside the tank, catalytic manganese-dioxide media works on your water. This media is specially designed to react with iron, manganese, and hydrogen sulfide, turning them into solid particles that the filter traps. It’s more effective than basic gravel or sand filters because it encourages a chemical reaction (oxidation) without adding anything to your water. This is why it’s well suited to handle both the rusty stains and the sulfur smell at once.

Tank Size That Matches Serious Water Needs

The tank measures 10 inches wide by 54 inches tall, holding enough media to treat large volumes of water reliably. It’s built to handle about 15,000 gallons per day, which means it can keep up with commercial or industrial water lines without getting overwhelmed. The tank itself comes with a lifetime warranty on the pressure vessel, so you know it’s built to last and won’t need replacing for decades under normal conditions.

Is This the Right Size for Your Property?

This system is designed for larger water users who have significant iron, manganese, or sulfur problems. It’s a good fit for buildings with commercial or industrial water demands where smaller residential filters wouldn’t keep up. For smaller homes or lower water use, a smaller unit would be more appropriate to avoid unnecessary regeneration cycles or wasted resources.

What’s Included and How to Proceed

The system includes a bypass valve, so you can isolate it during maintenance without losing water to your house. You also get 10 feet of discharge hose for the drain line. The pressure vessel carries a lifetime warranty, while the control valve and electronics are covered under the manufacturer's warranty terms.

Who this size is right for

At 15,000 gallons per day this is sized for a commercial or industrial process line.

The rated output assumes reasonable feed water and temperature. Colder or dirtier feed water lowers it, so choose a size above your true daily requirement.
