WSP Whole House Iron & Sulfur Filter - Rotten-Egg

If your water leaves orange or brown stains or smells like rotten eggs when you turn on the tap, this filter is designed to help reduce those issues. It uses a proven air-injection process to address iron staining and sulfur odors, improving water quality throughout your home.

The problem you're facing

Orange or brown rings in your toilet tanks, rusty stains on sinks and tubs, or a noticeable rotten-egg smell when you run the shower are clear signs of iron and sulfur in your water. These issues can leave a persistent film on shower doors, make towels feel stiff after washing, and even affect the taste of your coffee. These annoyances aren’t just cosmetic — they’re everyday frustrations that impact how you experience your water.

Why it's happening

Iron and sulfur naturally occur in many water sources. When iron is exposed to air, it oxidizes and leaves behind orange or brown deposits. Sulfur usually shows up as hydrogen sulfide gas, which causes the rotten-egg smell. The key check is a water test that measures iron and hydrogen sulfide levels. If these are elevated, it confirms the source of your staining and odor problems.

What it's costing you to leave it

Ignoring iron and sulfur in your water means more than just stains and smell. Iron buildup can shorten your water heater's lifespan by layering inside the tank, and the sulfur smell can make laundry and dishes less pleasant. You’ll also use more soap and detergent because these contaminants interfere with cleaning, plus spend extra time scrubbing stains that become harder to remove over time.

How this system helps

This system works by drawing air into the water, which changes dissolved iron and sulfur compounds into solid particles. These particles are then trapped by a special filtering media inside the tank and flushed out automatically during regular backwashing. This process reduces the iron staining and sulfur smell you notice around your home.

What this system can handle

Built around a reliable air-injection oxidizing tank with Katalox Light media, this filter is effective on both iron and hydrogen sulfide sulfur at levels common in well and municipal water supplies. It manages flow rates suitable for homes with one to six bathrooms, so it’s capable of handling moderate to heavy water use before it needs to regenerate. The system backwashes itself on a schedule, which keeps the media clean and ready to work without frequent manual maintenance.

What you actually get

When you order, you receive the complete system: a Fleck 2510 SXT air-injection control valve, an air-injection oxidizing tank, and the Katalox Light media engineered for oxidizing iron and sulfur. Included with the system is a bypass valve, so you can isolate the unit and keep water running to your home during any service or maintenance. There’s also 10 feet of discharge hose for the drain line. The tank itself carries a lifetime warranty against failure.

Is this the right size for you?

This filter is suitable for homes with one to six bathrooms, covering a wide range of typical household water use. If your water demand is smaller or larger, you might want to consider a different size or system to match your flow and iron/sulfur levels. Proper sizing ensures the system performs efficiently and lasts longer.

Living with it

Maintenance is straightforward. The system regenerates automatically by backwashing on a set schedule, flushing out built-up solids to the drain. You’ll mainly need to check the bypass valve during any service or plumbing work. Overall, it requires minimal day-to-day attention but benefits from your plumber inspecting it every year or two to ensure everything runs smoothly.

What it won’t do

This filter reduces iron staining and sulfur odor but does not soften water hardness or remove other contaminants like sediment or chlorine. If your primary issue is hard water scale or chemical tastes, a different or additional treatment system will be necessary. This unit is focused specifically on iron and hydrogen sulfide issues.
