WSP Whole House Iron & Sulfur Filter - All-In-One, 25"

The moment you open your dishwasher door after a cycle and see orange-brown stains on the racks or dishes, you’re facing iron and sulfur in your water. Along with that often comes a rotten-egg smell from hydrogen sulfide. This filter helps reduce those stains and odors throughout your whole home water supply.

What You Notice Every Day with Iron and Sulfur Present

It usually shows up in simple ways: orange-brown rings or deposits in your toilet tank, rusty stains on sinks or tubs, or a persistent sulfur smell when you run hot water, especially in the shower or from the kitchen tap. Your dishwasher may leave spots on glassware, and your laundry might look dingy or feel stiff after washing. These irritations aren’t just unpleasant; they mean your water has dissolved iron and hydrogen sulfide causing those stains and smells that don’t go away with ordinary cleaning.

How the Control Head Manages the Filter’s Cleaning

The control valve on top of this filter is automatic, running its own backwash cycle when needed. That means it lifts and rinses the filter bed inside, flushing out trapped iron, sulfur compounds, and manganese. This system also uses an air-draw feature, pulling in a pocket of air during backwash. This air reacts with the iron and sulfur in the water, turning them into particles that the filter bed can catch without chemicals. The control head’s port size is 1.25 inches, allowing for higher flow without slowing your water pressure.

The Media Inside That Does the Actual Filtering

What’s inside the tank is an oxidizing filter bed. The “oxidizing” part means it helps convert dissolved iron, manganese, and hydrogen sulfide—gases that cause the rotten-egg smell—into solid particles. These particles get trapped while clean water passes through. This media is what makes this filter suitable for tackling both staining iron and sulfur odors effectively. Because the system ships without media, we confirm exactly which media is best once we know your water’s condition.

The Tank’s Role and What It Can Handle

This filter comes with a durable pressure vessel tank covered by a lifetime warranty, giving you long-term peace of mind. The exact tank size is tailored depending on your household’s water needs, so we confirm that when we size the system. You can expect this setup to handle up to about 15,000 gallons of water per day, which is more than enough for large homes or commercial operations with steady water use.

Who This Filter Is Designed For

This system suits larger homes, commercial, or industrial water lines where iron, sulfur, and manganese cause noticeable staining and odor problems. With its 1.25-inch connections and high flow capacity, it’s not intended for small or average residential use. If your water use is lower or you have fewer bathrooms, a smaller system might be a better fit and more economical to operate.

What Comes with the System and How to Proceed

Included with your purchase is the control valve with automatic backwash and air injection, the pressure vessel tank backed by a lifetime warranty, a bypass valve so you can isolate the filter during maintenance without losing water to your home, and 10 feet of discharge hose for the drain line. We do not include the media inside, as we want to match it precisely to your water’s unique needs.
