WSP Whole House Iron & Sulfur Filter - All-In-One, IS-AIOCFMC10S

If your water leaves orange-brown stains on sinks and toilets, or your showers and laundry smell like rotten eggs, you have iron and sulfur in your water. The WSP Whole House Iron & Sulfur Filter is designed to reduce those stains and odors throughout your home.

The problem you’re living with

You’ve probably noticed the orange ring that forms inside your toilet tank. Maybe your shower door has a filmy buildup that soap can’t wash off. Your towels might feel stiff or rough, and your coffee doesn’t taste right—almost like you’re brewing with pool water. When you run the hot water, the rotten-egg smell hits you right away. These are all signs that iron and sulfur compounds are in your water, causing stains, odor, and general frustration.

Why this is happening

Iron and sulfur occur naturally in many water sources, especially well water. Iron dissolves in water and can leave rusty stains when it comes into contact with air. Sulfur, often in the form of hydrogen sulfide gas, creates that rotten-egg smell. The key test to confirm this is a simple water analysis checking iron and hydrogen sulfide levels along with pH. This tells you exactly what’s in your water and helps decide the right treatment.

What it’s costing you to leave it

Leaving iron and sulfur untreated means more time spent scrubbing orange-brown stains off fixtures and plumbing. Your water heater and appliances have scale buildup, which shortens their lifespan and lowers efficiency. You’ll use more soap and detergent to get clothes and dishes clean, and the persistent odor can make your home less comfortable. Over time, stains become harder to remove, potentially causing lasting damage to sinks, tubs, and laundry.

How this system fixes it

This filter uses a process called oxidation with air injection. Simply put, it introduces air into your water to turn dissolved iron and sulfur into solid particles. Then, the filter’s special media captures these particles, stopping them from reaching your taps. The system carefully measures how much water you use and backwashes just when necessary to keep the filter fresh and effective. It doesn’t rely on salt or chemicals, so there’s nothing to refill or haul.

What this system can handle

The WSP Whole House Iron & Sulfur Filter is built around a 10-inch by 44-inch polyglass tank designed to fit tight spaces. It treats iron and the rotten-egg sulfur odor throughout your whole home’s water supply. The air injection oxidation method works well for typical well water conditions, handling steady household use without frequent service. It backwashes based on actual water flow, not a fixed schedule, which saves water and keeps performance consistent. This makes it a step up from smaller filters that rely on timers or need salt-based regeneration.

What you actually get

The system includes the polyglass pressure tank covered by a lifetime warranty, so you won’t need to worry about replacing the main vessel. A bypass valve comes standard, allowing your plumber to isolate the filter and keep water running to your house during maintenance or repairs—something many competitors charge extra for. You also get 10 feet of discharge hose for the drain line, ready to connect at installation. The control valve and electronics have the manufacturer’s warranty according to their terms.

Is this the right size for you

This system fits homes that need a compact, reliable filter for iron and sulfur and have limited space for equipment. If your water problem is mild or you have a larger household with heavy water use, you might need a bigger unit. Conversely, if your iron and sulfur levels are low, a smaller filter might suffice. We will help you determine the right size based on your water test results and household needs.

Living with it

Maintenance mainly involves periodic backwashing, which the system controls automatically based on your water usage. Occasionally, your plumber may need to inspect or service the filter media or valve, typically once a year or as needed. There are no chemicals to add or salt to handle, which keeps upkeep straightforward. The bypass valve means your water stays on during service visits, so maintenance is less disruptive.

What it won’t do

This filter focuses on reducing iron staining and sulfur odor. It does not soften water or remove other contaminants like manganese, nitrates, or bacteria. If your water has multiple issues, a separate treatment system might be necessary for those specific concerns.
