WSP Whole House Iron & Sulfur Filter - Automatic

This automatic whole-house iron and sulfur filter from Water Softener Plus (WSP) helps reduce orange-brown iron staining and unpleasant rotten-egg smells caused by sulfur in your water. It uses a reliable oxidation and filtration process to handle these common water problems throughout your home.

The problem you’re living with

If you notice orange or reddish stains on your sinks, tubs, or toilet bowls, that’s a clear sign of iron in your water. You might also smell a rotten-egg odor, especially when you run hot water—this usually comes from sulfur compounds. These issues don’t just look and smell unpleasant; the stains can build up over time and become harder to scrub off, and the smell can make your water less pleasant for cooking or washing. You may also see a brownish tint in your laundry or find that your plumbing fixtures are dull or damaged from constant staining.

Why this is happening

Iron and sulfur naturally occur in many water supplies, especially in well water but sometimes in municipal water too. When iron is dissolved in your water, it stays invisible until it reacts with air and turns into solid particles that stain surfaces. The sulfur smell comes from hydrogen sulfide gas, which releases that rotten-egg odor when water is exposed to air or heat. A simple water test showing iron above a certain level or detecting sulfur gases confirms these problems are present in your supply.

What it’s costing you to leave it

Leaving iron and sulfur untreated means you’ll spend more time scrubbing stains from bathroom fixtures and laundry, and these stains can become permanent discoloration if ignored. Your water heater and appliances like dishwashers may face added stress from mineral buildup, reducing their lifespan and efficiency. You’ll also use more soap and detergent to get things clean, which adds ongoing costs. Plus, the odor and taste issues can make everyday water use less pleasant.

How this system fixes it

This system works by pulling your water through a tank filled with special filter media that encourages oxygen to react with the iron and sulfur compounds in your water—a process called oxidation. This reaction turns dissolved iron into tiny solid particles and reduces the sulfur odor. These particles get trapped in the filter media. The system then automatically cleans itself—backwashing to flush out the trapped iron so the filter keeps working well without you having to do much.

What this system can handle

This WSP iron and sulfur filter is designed to treat the full water supply to your home, handling the typical iron and sulfur levels found in well or municipal water. It can manage steady flows and works automatically to backwash and clear out buildup before it becomes a problem. The included bypass valve lets you isolate the system for servicing without shutting off your water, so you won’t lose water access during maintenance. It’s a step up from smaller units that may only treat part of your water or require more frequent manual cleaning.

What you actually get

The system includes a durable pressure tank covered by a lifetime warranty, ensuring the vessel that holds the filter media is built to last. It also comes with an automatic control valve and electronics that manage the backwash cycles, with their own manufacturer warranties. You’ll receive a bypass valve included in the package, which many competitors charge extra for, and 10 feet of discharge hose to connect to your drain line.

Is this the right size for you

This system suits homeowners who want whole-house treatment for iron and sulfur issues and who have water usage typical of a household up to moderate size. If you have very high water usage or unusually high iron or sulfur levels, you might need a larger or more specialized system. Conversely, if your problem is minor or you only need treatment for a single faucet or small area, a smaller or point-of-use filter might be a better match.

Living with it

Maintenance involves periodic backwashing cycles managed automatically by the system to keep the filter media clean and effective. Occasionally, a service visit by your plumber may be needed to check controls or replace worn parts over time, but the included bypass valve makes servicing straightforward without disrupting your water supply. Routine upkeep is reasonable and doesn’t require frequent manual intervention.

What it won’t do

This filter helps reduce iron and sulfur but does not address hardness minerals like calcium or magnesium, which cause scale and might require a separate water softener. It also won’t remove other contaminants such as bacteria, sediment, or chemical pollutants. For those problems, different or additional treatment systems would be necessary.
