WSP Whole House Air Injection Iron Filter

If your water leaves orange or reddish stains on sinks and toilets, or if you notice a rotten-egg smell when the hot water runs, you’re likely dealing with iron and sulfur in your water. The WSP Whole House Air Injection Iron Filter helps reduce these issues by treating your water across your entire home.

The problem you’re living with

You see orange or rust-colored rings inside your toilet tank. Your shower glass has a cloudy film that no amount of scrubbing fully removes. Towels feel stiff and dingy after washing, and your coffee sometimes tastes off, almost metallic. Plus, when you run hot water, there’s a faint but unmistakable rotten-egg smell. These signs point to iron staining and sulfur odors in your water, both of which can be a nuisance and a constant cleaning challenge.

Why this is happening

Iron and sulfur in water commonly come from well sources or certain groundwater supplies. Iron is a mineral that causes reddish or brown stains when it oxidizes—meaning it reacts with oxygen in the air. Sulfur, often in the form of hydrogen sulfide gas, produces that rotten-egg smell when it’s released from your water, especially when heated. The best way to check is with a simple water test measuring iron and sulfur levels, which your plumber or a water lab can do.

What it’s costing you to leave it

When iron and sulfur remain untreated, they don’t just cause stains and odors—they also leave deposits inside your plumbing and water heater. Over time, this build-up can reduce your water heater’s lifespan and make appliances work harder. You use more soap and detergent trying to get things clean, and cleaning itself takes longer and feels less effective. Stains on fixtures and laundry tend to get worse and can become harder to remove.

How this system fixes it

The WSP Whole House Air Injection Iron Filter uses a process called air oxidation. It injects air into your water to convert dissolved iron and sulfur into solid particles, which then get trapped and removed as water flows through the filter. This means less staining and a reduction in that sulfur smell throughout your entire home.

What this system can handle

This filter is designed to handle common levels of iron and sulfur found in residential water supplies. It treats all the water entering your home, ensuring that every tap benefits from cleaner water. The system works continuously, with cycles to flush out trapped iron and sulfur particles before they build up. It’s built to cope with typical household water demands and conditions, giving reliable performance without frequent maintenance interruptions.

What you actually get

The system includes a pressure tank backed by a lifetime warranty, offering long-term durability. A control valve manages the air injection and filtration cycles, covered by the manufacturer's warranty terms. You also receive a bypass valve at no extra cost—this lets you isolate the filter during servicing without shutting off your water supply. For waste water discharge, 10 feet of hose is included, making installation straightforward.

Is this the right size for you

This whole-house system suits owners dealing with moderate iron and sulfur issues who want to treat all the water in their home. If your water tests show very low iron or sulfur, a smaller, simpler filter might be enough. Conversely, very high levels or additional water quality problems may require a larger or more specialized solution. Free sizing help is available to guide your decision.

Living with it

Maintenance involves occasional backwashing and filter regeneration cycles, which the system handles automatically. You’ll need to check the system periodically and ensure the discharge hose and bypass valve function properly. Routine upkeep keeps performance steady and helps avoid service interruptions.

What it won’t do

This iron filter reduces iron and sulfur but does not soften hard water or remove other contaminants like chlorine or sediment. For hardness issues, a water softener would be needed alongside this system. If you have bacterial contamination or other chemical concerns, different treatment methods are required.
