WSP Whole House Iron & Sulfur Filter - All-In-One, Fleck 5600SXT

If your water leaves orange-brown stains on sinks, toilets, or laundry, or your hot water smells like rotten eggs, this iron and sulfur filter offers a dependable way to reduce those problems. It uses a chemical-free process to help clear iron and sulfur from your whole house water supply.

The problem you’re living with

Maybe you’ve noticed rusty orange rings forming inside your toilet tank, or that your white clothes look dingy and grey after washing. The shower door gathers a stubborn film, and the water sometimes smells unpleasant, like rotten eggs. These are common signs of iron and sulfur issues in your water. You’re scrubbing more often and feeling that your water just isn’t as clean or fresh as it should be.

Why it’s happening

Iron in water comes from natural deposits underground, especially if you have a well. When dissolved iron contacts oxygen, it turns into those orange or brown stains you see. The rotten egg smell comes from hydrogen sulfide gas, which can also be naturally present in groundwater. A simple water test showing elevated iron levels or that sulfur smell confirms these are the causes of your water problems.

What it’s costing you to leave it

Iron and sulfur can shorten the life of your water heater and appliances by building up scale and sediment. You’ll likely use more soap and detergent to get clothes and dishes clean, and even then, stains and odors can linger. Over time, the orange staining in sinks and tubs becomes harder to remove, meaning more time and effort spent cleaning and replacing worn fixtures.

How this system fixes it

This filter uses a process called air injection oxidation. It keeps a pocket of air inside the filter tank where oxygen reacts with the iron and sulfur dissolved in your water. This reaction changes them into solid particles that the filter media then traps. The system automatically flushes these particles out each day, so it keeps working with little attention from you and without adding any chemicals or salt to your water.

What this system can handle

The system is sized with a 10" x 44" mineral tank, making it suitable for smaller homes or moderate iron and sulfur levels. It works continuously at your main water line, protecting your plumbing, fixtures, and laundry from stains and odors. The automatic daily backwash cleans the filter media, maintaining performance without you needing to manage it manually. It’s a reliable choice if your iron or sulfur problem isn’t severe but still noticeable and bothersome.

What you actually get

Included is a mineral tank with a lifetime warranty on the pressure vessel itself. The Fleck 5600SXT control valve manages the air injection and regeneration cycles. You also get a 3/4" bypass valve, so you can isolate the system if needed without shutting off your water supply, plus 10 feet of discharge hose for the drain line. These components come ready to install by your plumber, giving you a complete system backed by solid warranties.

Is this the right size for you

This system fits homeowners with moderate iron or sulfur issues and smaller water usage. If your water tests show very high iron levels or your household uses a lot of water, a larger system or a different setup might be better suited. We can help you decide the right size based on your water test results and household needs.

Living with it

Maintenance is minimal. The system runs an automatic backwash every day, flushing out trapped iron and refreshing the air pocket. You’ll just need your plumber to check it yearly or if the bypass valve is used. There’s no salt or chemicals required, so ongoing costs are mainly water for the backwash and occasional media replacement after several years.

What it won’t do

This filter is designed for iron and sulfur reduction; it does not remove hardness minerals like calcium or magnesium. If you have hard water, a water softener is needed alongside this system. It also does not filter out bacteria, sediment, or other contaminants, so if those are concerns, a separate solution would be required.
