WSP Iron & Sulfur Filter - Catalytic MnO2

The WSP Iron & Sulfur Filter - Catalytic MnO2 is designed to reduce orange-brown iron stains and the rotten-egg smell caused by sulfur in your water. It uses a chemical-free oxidation process to trap these issues before they reach your taps, helping protect your home’s fixtures and surfaces.

When Appliances Fail Early Because of Stains and Smells

That water heater that broke down last year, the one your plumber said was ‘clogged with rust’? The shower glass that always has a cloudy film no matter how much you clean it? And the toilet bowl rings that come back every few days, stubborn and orange-brown. These are the signs of iron and sulfur problems running through your water. The smell of rotten eggs lingers in the hot water, and stains settle where water collects. It’s more than a nuisance — it’s a daily reminder that your water is working against you.

How the Control Head Keeps Your System Running Smoothly

The digital control valve on this filter keeps everything on track without your needing to intervene. It automatically starts a backwash cycle that lifts and rinses the media bed, clearing out trapped particles. The air-draw feature pulls in a pocket of air during backwash to chemically oxidize iron and sulfur compounds, all without adding chemicals to your water. A clear digital display shows the system’s status and lets your plumber adjust settings during installation or service.

The Media Inside: What Does the Work?

Inside the tank, a combination of media layers handles your water’s troublemakers. The catalytic manganese-dioxide media targets iron, manganese, and hydrogen sulfide (which causes that sulfur smell). Zeolite media further filters out sediment and turbidity, keeping the water clear. Below these is a graded gravel underbed that ensures water flows evenly through the media, making the treatment consistent and effective. This mix is tuned to handle common well water issues without complex chemicals.

The Tank Size and What It Means for Your Water Use

The filter sits in a 13-inch by 54-inch tank holding about 2.5 cubic feet of media inside. This size supports a service flow of roughly 10 gallons per minute, enough to keep up with average household use. That means you won’t notice slowdowns when a shower runs or multiple taps open. The tank is built to last and comes with a lifetime warranty on the pressure vessel itself, so you’re covered for the long haul.

Who Should Consider This Filter and Who Should Look Elsewhere

This system suits an average family home with three to four people, handling two to three bathrooms comfortably. If your household uses more water or has more bathrooms, you might want to consider a larger system to keep water flow steady. On the other hand, smaller homes or single-bathroom setups can look into smaller units better matched to lower flow demands.

What You Receive and How to Start

When you order the WSP Iron & Sulfur Filter, you get the tank and media, the 2510AIO digital control valve with air injection, and practical extras included in the price—a bypass valve so you can isolate the system during maintenance without shutting off your water, and 10 feet of discharge hose for the drain line. The tank itself carries a lifetime warranty. You won’t pay extra for shipping anywhere in the U.S., and we provide clear install and service manuals for your plumber. To get started, simply order online or contact us for sizing advice from people who handle water treatment every day.

Who this size is right for

This is rated for roughly 10 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 bathrooms.

Work out what runs together on a bad morning and size for that figure. Equipment starved of flow does not just run slowly, it stops treating properly.
