WSP Whole House Iron & Sulfur Filter - All-In-One, IS-AIOCFMC10T

If you’re struggling with orange-brown stains on fixtures or laundry, or a rotten-egg smell from your hot water, this whole-house iron and sulfur filter helps reduce those problems. It treats iron staining and sulfur odors using air injection oxidation without chemicals.

The problem you live with

Orange-brown rings in your toilet tank, rusty-colored spots on sinks and tubs, and hard-to-remove stains on clothes all point to iron in your water. If your hot water smells like rotten eggs, that’s hydrogen sulfide gas — the sulfur smell that’s strongest when water hasn’t run for a while or after heating. Both issues can make everyday tasks like showering, cooking, and laundry unpleasant.

Why it’s happening

Iron and sulfur often come from well water or certain local water sources where these minerals dissolve naturally underground. Hydrogen sulfide gas causes the rotten-egg smell, and it’s usually noticeable in hot water because heating releases the gas. The telltale test is a water sample that shows iron and sulfur levels above what you’d expect — a simple lab test confirms this.

What it’s costing you to leave it

Iron deposits build up inside your water heater and pipes, leading to reduced efficiency and potentially shortening their lifespan. Stains on fixtures and laundry demand more time and stronger cleaning products to manage. The sulfur smell can make showers and drinking water unpleasant, and the mild corrosion it causes may tarnish metal surfaces over time.

How this system fixes it

This system uses a process called air injection oxidation. It adds air into your water to convert dissolved iron and sulfur compounds into solid particles. These solids then get trapped in a filter media bed inside the system. The filter periodically cleans itself automatically by flushing the trapped particles to a drain.

What this system can handle

The WSP Whole House Iron & Sulfur Filter tackles both iron staining and hydrogen sulfide odors in your entire home’s water supply. It’s designed to maintain consistent performance without chemicals or extra pumps, handling typical household flow rates with a single-tank setup. The system backwashes and renews its air charge on a schedule programmed to your household’s water use, keeping odor and staining problems reduced day after day.

What you actually get

The system comes with a pressure vessel covered by a lifetime warranty, ensuring long-term durability. A bypass valve is included so you can isolate the filter during maintenance and keep water running to your home without interruption. Also included is 10 feet of discharge hose for the drain line, making installation easier for your plumber.

Is this the right size for you?

This model fits homes with moderate to high iron and sulfur levels and typical household water flow. If your water use is very low or your staining and odor issues are minor, a smaller system might be more suitable. Conversely, for very large homes or commercial settings, we recommend sizing up to handle higher flow and mineral loads effectively.

Living with it

Maintenance mainly involves occasional backwashing, which the system handles automatically. Periodically, your plumber will check the media bed and control valve to ensure they’re working properly. The included bypass valve simplifies service visits by allowing you to keep water flowing without shutoff during maintenance.

What it won’t do

This system reduces iron and hydrogen sulfide odors but does not treat water hardness, acidity, or other contaminants like sediment or bacteria. If you have those issues, additional treatment stages may be necessary, which we can help you design.
