WSP Whole House Iron & Sulfur Filter - Rust Stains

Water Softener Plus's WSP Whole House Iron & Sulfur Filter targets orange-brown iron stains and rotten-egg sulfur smells in your water supply. It uses catalytic manganese-dioxide media with an air-injection control valve to reduce these common nuisances throughout your home water.

What a Plumber Sees When They Inspect Your Setup

When a plumber checks your water supply, the first thing they likely notice is rust-colored buildup inside pipes or fixtures. This orange-brown staining doesn’t just look unpleasant; it often signals iron in the water that’s beginning to coat surfaces. Alongside this, they might detect a distinctive rotten-egg smell caused by sulfur compounds. Together, these issues mean your water is depositing iron and sulfur compounds that cause stains, odors, and can leave a metallic taste in your beverages. This buildup can also affect your plumbing and appliances over time.

How the Control Head Manages Treatment Cycles

The system uses an automatic control head designed to simplify maintenance. This valve pulls in a pocket of air into the water—the “air-draw” feature—which oxidizes iron and sulfur compounds naturally, without chemicals. Periodically, the system runs a backwash cycle that lifts the media bed and flushes the oxidized particles down the drain. You set how often regeneration happens, so it adapts to your water usage and load, saving water and salt compared to less precise units. The included control head is a robust 2510 SXT air-injection valve, known for reliability and efficient operation.

Why Catalytic Manganese-Dioxide Media Works Here

Inside the tank, catalytic manganese-dioxide media acts as the filtering agent. This media is specially designed to attract and bind iron, manganese, and hydrogen sulfide (which causes the sulfur smell). The “catalytic” part means it speeds up the reaction with the air drawn into the system, turning dissolved iron and sulfur into solid particles that can be rinsed away during backwash. This media is effective at reducing the orange iron stains and rotten-egg odor that can make laundry dingy and showers unpleasant.

The Tank and Its Capacity for Your Home

The system comes with a durable pressure vessel designed to hold the catalytic media and withstand daily use for years. While we don’t publish exact tank dimensions here, the tank is sized and confirmed during your purchase to match your household water needs. This ensures the media has enough contact time with your water for effective treatment while maintaining good flow throughout your home.

Fitting This System to Your Household Water Needs

This filter is intended for typical single-family homes on a whole-house water supply. It’s suited to handle enough water volume to treat all water entering the home, including kitchens, bathrooms, laundry, and outdoor spigots. If your household water use or iron/sulfur levels are unusually high, you might need a larger or dual-tank system instead. Conversely, smaller homes or point-of-use needs may be better served by a smaller filter.

What’s Included and What Happens Next

Your purchase includes the tank with catalytic manganese-dioxide media, the 2510 SXT air-injection control valve, a bypass valve so you can isolate the filter during service without shutting off your water, and 10 feet of discharge hose for the drain line. The tank comes with a lifetime warranty on the pressure vessel itself. We ship the complete system from Tampa with free U.S. shipping included in the price. You install this through your local licensed plumber. When you’re ready, place your order online to get started on cleaner, fresher water throughout your home.

Who this size is right for

What you are buying here 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.

There is no published capacity figure for this item, so we size it from your water rather than from a table. Send your peak flow rate and a water test and we will confirm what you need - it costs nothing and it avoids buying twice.
