WSP Air Injection Iron Filter

If your water leaves orange stains on sinks or toilets and smells like rotten eggs when you run the shower, the WSP Air Injection Iron Filter is designed to help reduce those issues. It treats iron staining and the sulfur odor by introducing air to oxidize and remove these common well water problems.

The problem you’re facing

Iron in water often shows up as reddish or orange stains on plumbing fixtures, toilets, and laundry. You might notice a metallic taste or see rusty sediment settling in your pipes. If your water smells like rotten eggs, that’s usually caused by hydrogen sulfide gas, which can be unpleasant and linger on towels or in your hot water. These issues can make daily chores harder and your home less comfortable.

Why it’s happening

Iron and hydrogen sulfide gases come from natural sources underground, especially in well water. The iron dissolves in water in a form you can’t see, but when it meets air, it changes into rust-colored particles that settle in your pipes or on surfaces. The rotten egg smell comes from hydrogen sulfide gas escaping when water’s pressure or temperature changes. A simple water test checking iron content and sulfur compounds confirms if these are your issues.

What it’s costing you to leave it

When iron builds up inside pipes and appliances, it can shorten their life by causing clogs and corrosion. That rusty film on your shower glass and fixtures is tough to clean and gets worse over time. Laundry may come out dingy or stiff, and your soap and detergent don’t work as well, which means using more to get clothes and dishes clean. Over time, these problems add up in money and effort.

How this system fixes it

The WSP Air Injection Iron Filter uses air to treat your water before it reaches your home. It sprays your water into tiny droplets inside an atmospheric tank, mixing it thoroughly with air. This process, called oxidation, changes dissolved iron and sulfur compounds into solid particles and gases that can be separated and removed. The system vents the odors away and captures the particles, reducing staining and smell without adding chemicals to your water.

What this system can handle

This filter is built to handle typical well water with moderate iron and sulfur levels. It works continuously to process your household water supply, helping reduce iron staining and that rotten-egg odor. It’s designed for steady performance, with a large tank that can hold enough volume to treat water for most homes before maintenance is needed. Compared to smaller units, it offers more capacity and can keep up with heavier use or higher iron levels before it requires attention.

What you actually get

The system includes a tank with a lifetime warranty on the pressure vessel itself, so that part is covered for life. It comes with a bypass valve included, letting your plumber isolate the filter for service without shutting off water to your whole house. You also get 10 feet of discharge hose for the drain line, making installation and maintenance easier. The control valve and electronics have their own manufacturer warranties.

Is this the right size for you?

This air injection iron filter suits most homeowners dealing with moderate iron and sulfur problems in their well water. If your water test shows very high iron levels or other contaminants, you might need a larger, more complex system. Conversely, if your iron or sulfur is very low, a smaller or simpler filter might be sufficient. We can help guide you based on your specific water test results.

Living with it

The system needs periodic maintenance to keep working well. You’ll need to check the air injector and vent components regularly and clean or replace parts as recommended. Some routine flushing or backwashing may be required to remove accumulated iron solids. It’s straightforward but does require some attention every few months or as your water condition changes. Having your plumber handle this upkeep is the easiest approach.

What it won’t do

This system is designed specifically to reduce iron staining and hydrogen sulfide smell. It won’t soften hard water minerals like calcium or magnesium, nor will it filter out bacteria, sediment, or other chemical contaminants. If you have those issues, you’ll need additional treatment equipment tailored for those specific problems.
