WSP Whole House Iron & Sulfur Filter - All-In-One, 25"

If your water leaves orange-brown stains on fixtures and laundry or smells like rotten eggs when you run the shower, this system is designed to help reduce those iron and sulfur problems throughout your whole home. It treats well water or other sources where these contaminants cause stain and odor issues.

The problem you’re dealing with

You’ve probably noticed rusty-colored rings in the toilet tank or reddish-brown stains on sinks and tubs. Your shower glass or tile might have a stubborn film, and towels feel less soft after washing. The worst is the sulfur smell—like rotten eggs—that comes up when hot water runs. These signs mean iron and sulfur are affecting your water daily.

Why it happens

Iron in water often comes from underground sources dissolving minerals as the water flows through soil and rock. Sulfur, commonly in the form of hydrogen sulfide gas, forms naturally in some well water or pipes. When water sits or heats up, that gas escapes, causing the rotten egg smell. The orange and brown stains are iron particles settling on surfaces. A simple water test measuring iron and sulfur levels confirms this is your issue.

What it’s costing you to leave it

Iron and sulfur don’t just stain; they shorten water heater life by building scale. Your dishwasher and washing machine may need more detergent to get clothes clean, and appliances can wear out faster. Cleaning stained surfaces takes more time and harsher chemicals, which only partly remove the marks. Over time, these problems become harder and more expensive to manage.

How this system helps

This filter uses air-injection technology to add a steady pocket of air inside the tank, which turns dissolved iron and sulfur into tiny particles. These particles can then be trapped by the filter media you load into the tank, clearing them from the water before it reaches your taps. The system automatically flushes itself to keep working without you needing to intervene.

What this system can handle

This unit is built on a 1.25-inch control valve that supports typical whole-house water flow, suitable for most homes. It helps reduce iron and sulfur levels by oxidizing dissolved particles and filtering them out. Because it ships without media, you or your installer can choose the exact filter media based on your water test—whether that's catalytic media for iron and sulfur or another specialty blend. It can handle iron and sulfur levels typical in well water or similar sources, with backwashing to keep the system fresh. The included bypass valve lets you isolate the unit during service without cutting off water to your home.

What you actually get

The system includes the pressure tank covered by a lifetime warranty for the vessel itself. The control valve, which manages air injection and backwash cycles, carries its own manufacturer’s warranty. You’ll also receive a bypass valve included in the price, allowing you to keep water flowing while servicing the filter. Ten feet of discharge hose for the drain line comes with the system. Media is not included and must be selected separately based on your water conditions.

Is this the right size for you?

This 25-inch system suits most homes with moderate to heavy iron and sulfur issues. If your household water use is unusually high or your water test shows very high contaminant levels, you might need a larger system. Conversely, smaller homes or lighter problems may be better served by a more compact unit. We recommend sending in your water test and ZIP code so we can help confirm the best size.

Living with it

Maintenance mostly involves replacing the filter media when it no longer captures iron and sulfur effectively. The system’s backwash cycle runs automatically, flushing accumulated particles down the drain. You’ll want to check the bypass valve occasionally and keep the drain hose clear. Since the media is separate, you can refresh just that part without replacing the entire system, which helps reduce upkeep costs over time.

What it won’t do

This filter is designed specifically for iron and sulfur problems. It does not address hardness (calcium and magnesium), bacteria, or chemical contaminants. If you have those issues, you’ll need dedicated systems such as water softeners for hardness or specialized filters for other contaminants.
