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

Cleaning orange-brown stains from sinks and toilets, scrubbing the shower door to clear rust-colored film, and dealing with that persistent rotten-egg smell takes time and effort. These are signs your water has iron and sulfur problems that keep coming back no matter how often you clean.

What You’re Facing Every Day

Every time you wipe down your bathroom or kitchen fixtures, you see that stubborn orange-brown staining reappear, especially around faucets, inside toilets, and on shower glass. Your laundry looks dull or greyish despite detergent, and towels can feel rough or stiff. And when you run hot water, that sulfur smell—like rotten eggs—fills the air. You might find yourself cleaning these spots often, only to watch them come straight back. It’s frustrating and eats up your time without solving the root problem.

How the Control Head Works to Keep Things Running Smoothly

The system includes an automatic control valve called the control head. It manages cleaning cycles for the filter tank automatically. When the filter media in the tank gets clogged with iron and sulfur particles, the control head starts a backwash cycle. This lifts and rinses the filter bed to clear out trapped contaminants, then resets itself. It also draws in a small air pocket to help oxidize iron and sulfur naturally—without chemicals. You set it to match your household’s water use, which helps save water and extends the filter media’s life.

The Media Inside: Why It’s the Right Choice for Iron and Sulfur

Inside the tank, there’s a bed of catalytic manganese-dioxide media designed specifically to target iron, manganese, and hydrogen sulfide—those are the usual causes of staining and sulfur smell. This media helps convert the dissolved metals and sulfur into solid particles that the filter can trap. Alongside this, granular activated carbon is included to reduce chlorine, taste, and odor issues. This combination means your water not only looks better but tastes better too, with fewer off smells.

The Tank and What It Means for Your Home

The system sits inside a pressure vessel tank designed for whole-house water treatment. While the exact tank size depends on your home’s specific water needs and will be confirmed when we size your system, it is built to handle a typical single-family home’s daily water use. It’s sturdy and backed by a lifetime warranty on the tank itself, so you know the core pressure vessel will last for years.

Who Should Consider This System

This filter suits homes with an iron and sulfur problem that affects the entire water supply. It’s best for those with a typical single-family home’s water flow and volume. If your water use is much higher or you have unusual water chemistry, you might need a larger system or a different setup, which we can help you determine. Homes with only minor staining might find a smaller unit sufficient, but this system covers a broad range of iron and sulfur levels found in many households.

What You Get When You Order This System

This iron and sulfur filter comes complete with a bypass valve included in the price. That means you can isolate the system for service without losing water to the whole house. Ten feet of discharge hose for the drain line is also part of the package. The pressure vessel tank carries a lifetime warranty, giving you long-term peace of mind. The control valve and electronic components carry their own manufacturer’s warranty. We ship everything from Tampa with free U.S. delivery.
