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

If your water leaves orange-brown stains on fixtures and laundry, or your hot water smells like rotten eggs, you’re likely dealing with iron and sulfur in your supply. The WSP Whole House Iron & Sulfur Filter - All-In-One, Katalox, C-Series is designed to help reduce these problems across your entire home water system.

The Problem

You’ve noticed stubborn orange rings around your toilet tank, rusty smudges on sinks, or brown stains in your bathtub. Maybe your laundry comes out dingy despite using plenty of detergent. On top of that, when you run hot water, there’s a clear rotten egg smell that won’t go away. These are signs that iron and sulfur are present in your water, and they’re causing stains and unpleasant odors that affect daily life.

Why It’s Happening

This happens because your water contains dissolved iron and hydrogen sulfide gas. When iron in your water meets the air, it oxidizes and forms those orange-brown particles that settle on surfaces. Hydrogen sulfide creates that rotten egg smell, especially noticeable when water is heated. The simplest way to confirm this is with a water test that measures the iron and sulfur levels, which your local lab or certified tester can provide.

What It’s Costing You To Leave It

Iron and sulfur in water aren’t just an eyesore or smell problem. The iron particles can build up inside your water heater and pipes, reducing efficiency and shortening their lifespan. You’ll use more soap and detergent to get clothes and dishes clean, and your appliances may wear out faster as they work harder against mineral deposits. Plus, the more you let these stains settle, the tougher they are to remove—meaning more time spent scrubbing and less satisfaction with your water quality.

How This System Fixes It

This filter uses a process called oxidation and filtration. The system injects air into the water, turning dissolved iron and sulfur into solid particles. These particles are then trapped in the filter media, which is specially designed to hold iron, manganese, and sulfur compounds until the system cleans itself automatically. This continuous cleaning cycle keeps your water clear and helps reduce the odors and stains you’ve been dealing with.

What This System Can Handle

The WSP Whole House Iron & Sulfur Filter - All-In-One uses premium Katalox-Light® media inside a robust 10" x 54" tank. It’s built to handle well water or municipal supplies with moderate to high levels of iron, manganese, and hydrogen sulfide. The control valve’s air-draw and backwash cycles are independently programmable, so the system uses air efficiently to oxidize contaminants and backwashes to drain without wasting water. It’s designed for whole-house use and can treat larger volumes of water between regenerations compared to smaller units, making it suitable for homes with multiple bathrooms or high water use.

What You Actually Get

The system includes the black polyglass mineral tank covered by a lifetime warranty, ensuring long-term durability. The Connected Series Air Draw Meter Control Valve with Bluetooth lets you monitor and program the system from your smartphone using the free Legacy View app. A bypass valve is included so you can isolate the filter during maintenance without shutting off water to your home. The package also comes with 10 feet of discharge hose for connecting the drain line. Plumbing connections are selected separately based on your setup.

Is This the Right Size for You?

This 10" x 54" filter is well-suited for average to larger homes dealing with combined iron and sulfur issues, especially if you’re treating water from a well or a source with elevated mineral content. If your water use is low or your iron and sulfur levels are very mild, a smaller unit might suffice. Conversely, very large properties or very high contaminant levels might require a larger system or additional treatment steps, which we can help you identify during sizing.

Living With It

You can expect the system to regenerate automatically on a schedule you set based on your water use and contaminant levels. Maintenance mainly involves checking the bypass valve and ensuring the drain hose remains clear. Because it uses durable components and a lifetime-warranted tank, you won’t face frequent part replacements. Bluetooth connectivity helps you keep tabs on performance without manual checks.

What It Won’t Do

This filter helps reduce iron, manganese, and hydrogen sulfide odors and staining but does not soften hard water minerals like calcium or magnesium. It also doesn’t remove bacteria, sediment, or chemical contaminants. For those, you’d need separate filtration or treatment systems designed for hardness, microbiological concerns, or chemical filtration.
