WSP Whole House Iron & Sulfur Filter - Black Stains Bitter Taste

Orange-brown stains and a rotten-egg smell are more than nuisances—they quietly wear out your appliances and force you to use more detergent and energy. The WSP Whole House Iron & Sulfur Filter helps reduce these problems by treating iron and sulfur before they reach your taps and appliances.

The unseen toll of iron and sulfur in your water

When your water leaves orange or brown stains on sinks, toilets, and laundry, or when it smells like rotten eggs, it's costing more than just appearance and comfort. These iron and sulfur compounds build up inside water heaters and appliances, forming scale that cuts efficiency and shortens lifespan. You may be using extra detergent to fight dingy laundry or scrubbing stubborn stains from glassware and fixtures. Over time, these issues add up in time, effort, and utility bills.

An automatic system that takes care of itself

On top of the tank, the control head manages the entire cleaning cycle for you. It automatically backwashes the filter bed on a schedule, lifting and rinsing the collected iron and sulfur particles to drain. This process also introduces an air pocket—no chemicals needed—using natural oxidation to convert dissolved contaminants into solids the media can trap. The control head renews the filter bed each time it backwashes, keeping it working efficiently with minimal attention from you.

Oxidizing media designed for iron, manganese, and sulfur

Inside the tank, the filter bed contains a special oxidizing media. This media targets iron, manganese, and hydrogen sulfide—the compound responsible for the rotten-egg smell. It chemically changes these dissolved substances into solid particles that the filter traps before they can stain your fixtures or taste bitter in your water. Choosing the right media is key because it handles the oxidation process naturally and keeps your water clearer and cleaner without added chemicals.

A sturdy tank, sized to fit your home’s water supply

The system’s pressure vessel holds the filter media and water while the treatment happens. While we confirm the exact tank size when sizing for your home's specific water supply and flow, the vessel is robust and built to last. It comes with a lifetime warranty on the tank itself, so its durability is guaranteed. The system is designed to fit the whole-house water supply of a typical single-family home, making sure all your tap water benefits from the treatment.

Ideal for homes with moderate iron and sulfur concerns

This filter suits households dealing with noticeable iron staining, manganese deposits, and that characteristic rotten-egg odor from hydrogen sulfide. It’s well-matched to a standard single-family home’s water use and flow. If your home has very high iron or sulfur levels, or a larger water demand, you might need a different system with higher capacity. Likewise, if your problems are minimal, a smaller unit may suffice.

What’s included and what comes next

Your order includes a bypass valve so you can isolate the system during maintenance without stopping water flow to your home—a feature often sold separately by others. There’s also 10 feet of discharge hose for the drain line. The pressure tank carries a lifetime warranty, while the control valve and electronics come with the manufacturer’s standard coverage. Ordering is simple, with free U.S. shipping included. Once you place your order, we help confirm the right size for your water conditions to make sure it fits and performs as expected.

Who this size is right for

Practically speaking, 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.
