WSP Whole House Iron & Sulfur Filter

If your water leaves orange-brown stains on fixtures or smells like rotten eggs when you run a shower or tap, this whole-house filter is designed to help reduce those iron and sulfur problems. It works continuously to improve water quality throughout your home.

The problem you’re facing

Do you notice rust-colored stains around the toilet bowl or sink? Does your hot water sometimes smell like rotten eggs? These are common signs of iron and sulfur in your water. The iron causes those orange-brown marks that are hard to scrub off, and sulfur releases hydrogen sulfide gas, which smells unpleasant and can make water taste off. It’s frustrating, especially when it affects your laundry, dishes, and even your morning coffee.

Why this happens

Iron and sulfur often come from well water or certain groundwater sources. Iron dissolves in water and then deposits as rust when exposed to air or heat, causing stains. Sulfur bacteria or hydrogen sulfide gas produce that rotten egg smell. A simple water test for iron content and sulfur presence can confirm if these are the causes behind your staining and odor.

What it costs you to leave it untreated

Iron and sulfur buildup can shorten your water heater’s life by clogging pipes and heating elements. You may find yourself using more soap and detergent to get clothes and dishes truly clean. Those rusty stains become harder to remove the longer you wait, and the odor can make household tasks less pleasant. Over time, your appliances and plumbing have to work harder, which can lead to earlier repairs or replacements.

How this system helps

This filter uses air injection oxidation to reduce iron and sulfur from your water. In simple terms, it injects air into the water to change iron and sulfur into solid particles that can be trapped in the filter, preventing stains and odors from reaching your taps. It works continuously, treating all the water coming into your home so every faucet benefits.

What this system can handle

The WSP Whole House Iron & Sulfur Filter is built to manage typical well water problems with iron and sulfur, and it helps reduce manganese too. It is designed for whole-home use, handling steady water flow across your household’s daily needs. The system can run for days between cleanings, depending on your water’s iron and sulfur levels, making it suitable for average to moderately high concentrations. It’s a step up from smaller point-of-use filters, able to work consistently for a full household.

What you actually get

The system includes a pressure vessel with a lifetime warranty, so the main tank is covered for as long as you own it. It comes with a bypass valve at no extra cost — this lets you isolate the filter without shutting off water to your house when it’s time for maintenance. You also receive 10 feet of discharge hose for connecting the system’s drain line. The control valve and electronics carry the manufacturer’s standard warranty, details of which come with your system.

Is this the right size for you?

This filter fits well for homeowners dealing with iron and sulfur at levels common in many private wells and groundwater sources. If your household uses considerably more water or has extremely high iron or sulfur levels, you might need to size up or consider additional treatment steps. Conversely, if your issues are mild and only affect a single faucet, a smaller, point-of-use filter could be sufficient.

Living with it

The system requires periodic maintenance, mainly cleaning or replacing filter media and servicing the control valve as indicated by your water usage and quality. How often depends on your water’s iron and sulfur content; typical intervals range from several months to a year between service visits. Maintenance is straightforward and can be handled by your local licensed plumber. The included bypass valve keeps water running during any service work.

What it won’t do

This filter does not remove hardness minerals like calcium or magnesium, so it won’t stop scale buildup from hard water. It also doesn’t address other contaminants such as bacteria, viruses, or chemical pollutants. For those issues, you would need additional or different treatment systems designed specifically for them.
