WSP Whole House Iron & Sulfur Filter - All-In-One, C-Series, C-Series

If your water leaves orange-brown stains around sinks and toilets, or your shower and laundry smell like rotten eggs, your water likely contains iron and sulfur. The WSP Whole House Iron & Sulfur Filter - All-In-One, C-Series is designed to reduce these common and stubborn issues for your entire home.

The Problem

When iron is present in water, you often notice orange or reddish-brown stains on plumbing fixtures, toilet tanks, and laundry. It can leave a metallic taste or cause your clothes to look dingy. Sulfur, usually as hydrogen sulfide gas, creates a distinct rotten-egg smell in your water, noticeable when running a shower or filling a glass. Both problems are more than just nuisances—they affect your daily comfort and require extra cleaning.

Why It’s Happening

Iron in water usually comes from underground sources or corroding pipes, while sulfur often appears as hydrogen sulfide gas in well water. The main way to confirm it’s your issue is a water test that checks iron and sulfur levels. High iron shows up as dissolved or particulate rust, and sulfur presence is confirmed by a smell test or lab analysis for hydrogen sulfide. Knowing these levels helps match the right system to your water.

What It’s Costing You to Leave It

Iron stains can build up inside your pipes and water heater, shortening their lifespan. They cause mineral deposits that make appliances work harder, increasing energy use. The sulfur smell can linger on laundry and dishes, and that persistent rotten-egg odor detracts from your water’s enjoyment. Plus, cleaning stains takes time and strong chemicals that wear down surfaces.

How This System Fixes It

This filter uses air injection to oxidize iron and sulfur compounds in your water. Oxidation means it adds oxygen, which turns dissolved iron and sulfur into solid particles. These particles are then trapped by the filter media inside the tank and flushed away during cleaning cycles. This process reduces staining and sulfur odors without adding chlorine or other chemicals.

What This System Can Handle

The WSP Whole House Iron & Sulfur Filter built on the C-Series control platform is designed for homes with moderate iron and sulfur levels. It treats your entire household’s water, enough to keep up with daily use without frequent backwashing. The system’s programmable air-draw and backwash cycles save water by separating air injection from filter cleaning, meaning it only backwashes when necessary. It’s suitable for well water sources with typical iron and sulfur levels, and its capacity fits smaller to medium-sized homes with average water use and moderate mineral loads.

What You Actually Get

This unit includes a 10-inch by 44-inch black polyglass mineral tank built to last, covered by a lifetime warranty on the tank itself. The control valve with Bluetooth-enabled programming lets you set and monitor air and backwash cycles via a free smartphone app. A bypass valve is included, so you can isolate the filter for service without shutting off water to the house. You also get 10 feet of discharge hose for drain line connection. Media and support bed come sized for sulfur and iron reduction. The electric valve and electronics carry the manufacturer’s warranty terms.

Is This the Right Size for You

This system fits smaller to medium homes with moderate iron and sulfur levels. If your household uses a lot of water daily, or if iron and sulfur concentrations are very high, a larger system with greater capacity might be more suitable. Conversely, if your iron and sulfur issues are minimal, a simpler or smaller filter could suffice. The WSP team will help confirm the best size when you request a quote.

Living With It

Maintenance mainly involves occasional reprogramming through the smartphone app and ensuring the bypass valve operates smoothly. The system performs self-cleaning cycles, so you won’t need to intervene often. Over time, the filter media may require replacement, which your service plumber can handle. The included bypass valve simplifies servicing without interrupting your water supply.

What It Won’t Do

This system reduces iron and sulfur but does not remove hard minerals like calcium or magnesium that cause water hardness. If your water is also hard, a separate or combined water softener would be needed. It does not treat bacteria, nitrates, or other chemical contaminants. For those issues, specialized treatments like disinfection or reverse osmosis are necessary.
