WSP Whole House Iron & Sulfur Filter - All-In-One, Catalytic MnO2, Control Flow

The WSP Whole House Iron & Sulfur Filter is designed for homes dealing with persistent orange-brown stains and that rotten-egg smell from sulfur in well or municipal water. It treats these issues at the source, protecting your laundry from discoloration and fabrics from roughness caused by iron and sulfur compounds.

What Your Laundry Is Showing You

Your clothes aren’t just dull—they’re stained with orange-brown marks that no amount of detergent seems to fix. Whites may be turning a dingy shade, and colors look faded faster than they should. Towels come out rough and scratchy, not soft and fluffy. It takes longer to get grease and dirt out, and the washing machine drum and pipes may build up residue. This is the clear sign that iron and sulfur are in your water, affecting not only your laundry but the overall feel and lifespan of your fabrics.

How The Control Head Works For You

The system uses a metered control head that tracks how much water you use and triggers cleaning cycles only when needed. It automatically backwashes the media bed, lifting and rinsing trapped particles to keep the system working efficiently. An air-draw feature pulls in an air pocket to chemically oxidize iron and sulfur compounds without adding chemicals. This precise, demand-based approach saves water and effort compared to timer-driven systems.

The Media That Does The Heavy Lifting

Inside the tank, catalytic manganese-dioxide media targets iron, manganese, and hydrogen sulfide, the source of that rotten-egg smell. This media works by speeding up the natural oxidation process, turning dissolved iron and sulfur into solid particles that can be filtered out. It handles these contaminants without requiring harsh chemicals, which means less hassle and fewer ongoing costs.

The Tank Size And What It Means

The tank is a 10-inch by 54-inch pressure vessel holding about 2 cubic feet of media. This size balances treatment power with a footprint that fits most home mechanical rooms. It provides enough capacity to handle flow rates up to about 12 gallons per minute, suitable for large households with multiple bathrooms and higher water demand.

Who Will See The Biggest Benefit

This filter suits homes with five or more occupants and three to four bathrooms, where iron and sulfur issues are frequent and persistent. It’s an option for people who want steady, chemical-free treatment for these problems without constant maintenance. Homes with lighter use or fewer bathrooms might consider a smaller system; those with very high water use or unusual water problems may need a custom solution.

What Comes With The Filter And What’s Next

The system includes a lifetime warranty on the tank itself, ensuring the pressure vessel will last. The control valve and electronics have the manufacturer’s own warranty terms. A bypass valve is included, letting you isolate the filter for service without shutting off water to your home. Also included is 10 feet of discharge hose for the drain line.

Who this size is right for

This is rated for roughly 12 gallons per minute of service flow, which suits a large home - around 5 or more people with 3-4 bathrooms.

Flow rate matters more than tank size here: add up the fixtures that could realistically run at the same time and make sure this covers them. If you land close to the limit, go up rather than down.
