WSP Whole House Iron & Sulfur Filter - All-In-One, IS-AIO10S

Your recent water test showed iron levels high enough to leave orange-brown stains on your sinks, tubs, and toilet tanks. Alongside that, the faint but persistent rotten-egg smell in your hot water isn’t just unpleasant—it’s hydrogen sulfide gas in your water supply turning your morning shower into an ordeal.

Recognizing the Signs of Iron and Sulfur in Your Water

Orange-brown rings and stains that don’t scrub away easily, a film on shower doors, and towels that start to feel stiff after washing—all point to iron in your water. The rotten-egg smell, strongest when water first runs after sitting in pipes, tells you hydrogen sulfide gas is present. These issues often show up in well water or certain municipal supplies. The smell is not just a nuisance; it’s an indicator of sulfide compounds dissolved in your water.

How the Control Head Acts Automatically to Keep Your Water Clean

The control head on this filter runs an automatic backwash cycle that lifts and rinses the media bed inside the tank. This keeps the filter clean and working efficiently without you needing to intervene. It also uses an air-draw mechanism that pulls in a pocket of air at the top of the tank. This air pocket chemically changes the sulfur compounds in the water without added chemicals, turning them into tiny solids the system can then flush away during backwash. This process renews itself automatically to keep your water odor-free and clearer.

The Media Inside that Targets Iron and Odors Without Chemicals

Inside the tank, there’s a layer of granular activated carbon which is excellent at reducing chlorine, improving taste, and cutting down odors. Below that, the air-injection oxidation media handles iron and sulfur by using the air pocket to convert dissolved sulfur gas into solid particles. These particles get trapped and removed during backwash. This combination suits the dual problem of iron staining and rotten-egg smells better than just a carbon filter or a softener alone.

About the Filter Tank and How It Fits Your Home

The system comes with a durable pressure vessel designed to hold the filter media and handle typical whole-house water flow. While we confirm the exact dimensions when sizing your system, the tank is sized to suit a single-family home’s main water supply. It’s built with a lifetime warranty on the tank itself, so you won’t need to worry about that pressure vessel failing.

Which Homes This Filter Serves Best and When to Consider Other Options

This filter is built for a typical single-family home with common iron and sulfur levels causing stains and smells. Its capacity and flow rate cover average daily household water use comfortably. If you have a very large home, unusually high levels of iron or sulfur, or multiple bathrooms running simultaneously at full flow, you should consider a larger or different system to handle that load effectively.

What Comes with Your Purchase and How to Proceed

When you order this filter, it ships from Tampa with free U.S. delivery included. The package contains the filter tank with the media inside, the control head with automatic backwash and air-injection features, a bypass valve so you can isolate the system during service without shutting off your water supply, and 10 feet of discharge hose for the drain line. The tank comes with a lifetime warranty, while the control valve and electronics have the manufacturer’s standard coverage. Once you receive it, installation is straightforward for your licensed plumber. To get started, order online and size confirmation support is available to ensure the system matches your water use and test results.

Who this size is right for

This is a whole-house system, plumbed into the main line so every tap in the house is treated. On a typical 1-inch service line that means a single-family home.

Because no fixed capacity is published for this item, the honest answer is that your own figures decide it. Send us your peak flow in gallons per minute and a water test and we will check the sizing for you, at no charge, before you buy.
