WSP Whole House Iron & Sulfur Filter - All-In-One, 5"

If your water leaves orange-brown stains on fixtures and laundry or smells like rotten eggs when you turn on the tap, this system helps reduce those common iron and sulfur problems across your entire house. It’s built to handle larger homes and higher water demand without chemicals.

The problem you’re facing

Orange or rust-colored stains around sinks, toilets, and bathtubs can be frustrating and stubborn. You might notice a reddish ring inside the toilet tank or that your laundry looks dingy even after washing. If your water smells like rotten eggs when you run a shower or fill a glass, that’s the sulfur (hydrogen sulfide) at work. Both iron and sulfur cause these issues, leaving you scrubbing stains and dealing with unpleasant smells daily.

Why this is happening

Iron and sulfur in water come from natural sources underground, often entering your well or supply line. Iron in water is usually dissolved and invisible until it meets air, where it turns into solid particles that stain. Sulfur creates that rotten-egg odor when hydrogen sulfide gas is present. A simple water test for iron and hydrogen sulfide confirms these issues and helps identify the levels you’re dealing with.

What it’s costing you to leave it untreated

Leaving iron and sulfur untreated means stains build up on toilets, sinks, and dishware, which get harder to remove over time. Your water heater and plumbing can develop scale and corrosion, shortening their lifespan and efficiency. You’ll also use more soap and detergent because the minerals interfere with cleaning, and that stiff feeling on towels or off tastes in beverages like coffee often come from these contaminants.

How this system helps reduce those problems

This filter uses air injection to oxidize iron and sulfur in your water. Simply put, it adds a controlled amount of air that turns dissolved iron and sulfur into tiny particles. These particles get caught in the filter’s media bed, so the water coming into your home has fewer staining minerals and less odor. The system automatically cleans itself by backwashing, which flushes out the trapped particles to keep it working efficiently without chemicals.

What this system can handle

Designed for larger homes or properties with high water demand, this system uses a 1.5-inch composite control valve that moves water faster without losing treatment quality. It manages iron, manganese, and sulfur odor in well or municipal supplies, working continuously even when multiple taps run at once. The system’s self-cleaning cycle keeps the media bed fresh to maintain performance, and it’s sized to handle bigger plumbing lines and frequent use without rushing the water through too quickly.

What you actually get

This unit includes the pressure vessel covered by a lifetime warranty, which means the tank itself is protected for the life of the system. The control valve and electronic parts carry the manufacturer’s standard warranty. You’ll also find a bypass valve included, allowing you to isolate the filter during maintenance while keeping water running to your home. Finally, 10 feet of discharge hose is provided for the backwash drain line, so you have what’s needed to connect it properly.

Is this the right size for you

This filter suits larger homes or facilities with many bathrooms or high simultaneous water use. If you have a smaller home or lower water demand, a smaller unit might be more efficient and cost-effective. Accurate sizing depends on your water’s iron and sulfur levels, as well as peak flow rate—sending your water test results and ZIP code to WSP helps confirm if this system matches your needs.

Living with it

The system operates automatically, handling air injection and backwash cycles without your intervention. Periodic maintenance involves checking the system and ensuring the drain line and bypass valve function properly. The effort required is moderate, mostly routine inspections and occasional servicing by your plumber. There’s no need to add chemicals or replace media frequently—this is a low-maintenance, self-renewing system.

What it won’t do

This filter helps reduce iron, manganese, and sulfur odor but won’t address other issues like hardness minerals (calcium, magnesium), bacteria, or sediment that requires separate treatment. If your water has those problems, you’ll need additional or different systems designed specifically for them.
