WSP Iron & Sulfur Filter - Katalox

If your water leaves orange-brown stains on fixtures and laundry or smells like rotten eggs when you run a shower or tap, this system helps reduce those iron and sulfur problems. It treats well water issues that cause staining and odor, improving your water’s appearance and smell.

The problem you see and smell

You might notice orange or reddish-brown rings around your toilet tank or sinks. Your shower doors and bathroom tiles develop a stubborn film. Towels feel rough or dingy after washing, and your coffee tastes off, like a swimming pool. When you turn on the hot water, it smells like rotten eggs. These are signs your water contains iron and sulfur.

Why this happens

Iron in water often comes from rust in underground pipes or natural deposits in wells. It shows up as orange or brown stains because iron oxidizes, meaning it reacts with oxygen and changes form. Hydrogen sulfide gas, which smells like rotten eggs, usually comes from sulfur bacteria in wells or decaying organic material underground. Testing your water for iron and hydrogen sulfide will confirm if these are the causes.

What it costs you to leave it

Iron build-up can shorten your water heater’s life by causing scale and rust inside the tank. Sulfur odors can make everyday water use unpleasant and affect laundry and dishwashing results. Stains on fixtures become harder to clean over time, and appliances like coffee makers and washing machines can suffer from deposits and clogging. You end up spending more on cleaning and appliance repairs.

How this system helps

This filter uses a process called oxidation and filtration. Inside, a special material called Katalox Light contains manganese dioxide, which reacts with iron and hydrogen sulfide in the water. It changes them into solid particles that can be trapped and removed as the water passes through, reducing stains and smells before the water reaches your taps.

What this system can handle

This iron and sulfur filter is designed to reduce iron, hydrogen sulfide (the rotten-egg smell), and manganese, all common well water problems that cause staining and odor. It works continuously, treating the water as you use it without needing frequent manual attention. If your water has higher levels of these substances, this system handles more before it needs service compared to smaller filters. It’s built to keep working efficiently for a household or small facility, depending on your water usage.

What you actually get

The system includes a pressure vessel with a lifetime warranty on the tank itself, so you have lasting protection where it matters most. There’s a bypass valve included at no extra cost, letting you isolate the filter for maintenance without cutting off water to your home. Also included is 10 feet of discharge hose for the drain line, ready for your plumber to connect.

Is this the right size for you?

This filter suits homes or facilities facing moderate to heavy iron and sulfur issues in their water supply. If your water tests show only low levels of iron or sulfur, a smaller or simpler solution might be enough. For very high levels or other water problems, you’d need a larger or different system. We can help you figure out the best fit based on your water test results.

Living with it

Maintenance mainly means occasional backwashing and media replacement as needed, typically every few years, depending on your water quality and usage. The included bypass valve makes servicing straightforward, and the system does not need electricity to operate continuously. Your plumber can handle installation and any repairs using parts that remain available long-term.

What it won’t do

This filter is not designed to remove hardness minerals like calcium or magnesium, nor does it treat bacteria or viruses. It also doesn’t remove chemical contaminants or sediment heavier than the particles it oxidizes. For those issues, you would need a dedicated water softener, disinfection system, or sediment filter in addition.
