WSP Whole House Iron & Sulfur Filter - Well Water

Water Softener Plus offers the WSP Whole House Iron & Sulfur Filter - Well Water to tackle stubborn orange-brown iron stains and the rotten-egg sulfur smell that often come with well water. Designed to clear these issues for average to larger homes, this system provides reliable treatment with an included bypass valve and lifetime warranty on the tank.

When Iron and Sulfur Filters Didn’t Make the Cut

You’ve dealt with orange rings around the toilet tank and the persistent rotten-egg odor in the shower that no quick fix or cheap filter could handle. You might have tried simple filters or additives that faded the staining briefly or masked the smell, but the stubborn discoloration and sulfur scent keep coming back. Cleaning feels endless, and the laundry seems duller by the day. Finding a system that actually lasts and is straightforward to maintain has been frustrating.

The Control Head that Works for Your Water Use

This system uses a metered control head that tracks the exact water you use. It automatically triggers a backwash cycle that lifts and rinses the media bed, clearing out the collected iron and sulfur compounds. You set it once, and it runs as needed, saving water and salt by avoiding unnecessary cycles. The control valve is a sturdy model designed to handle air injection, which helps break down iron and hydrogen sulfide, the source of that sulfur smell.

Media Made to Target Iron, Sulfur and Hardness

Inside the tank is a carefully balanced blend of media. The catalytic manganese-dioxide media works to reduce iron, manganese, and the rotten-egg sulfur smell by oxidizing these elements and trapping them. Alongside this are two kinds of cation exchange resin—one with 10% cross-linked resin that lasts longer in chlorinated water and another high-capacity resin—both aimed at reducing calcium and magnesium hardness. This combination helps prevent scale buildup while also cleaning out iron and sulfur effectively.

Tanks Sized to Match Your Home’s Needs

The system comes in three tank sizes with media volumes ranging roughly from 1 to 2 cubic feet. The tanks are standard fiberglass pressure vessels designed for durability and covered by a lifetime warranty, so the main hardware is built to last. The size you get determines the softening capacity—starting around 32,000 grains and going up to about 64,000 grains, enough to handle iron and sulfur problems in homes from two to seven people, depending on the model.

Who Should Choose This Filter

This filter suits average family homes with two to four occupants and two bathrooms, but it also has a larger version for bigger households with three to four bathrooms and up to seven people. If your household is smaller or water use is very low, a smaller filter might be more efficient. Conversely, for very large properties or commercial applications, you would need to explore options with higher flow rates or capacity.

What You Receive and How to Get Started

Ordering includes the pressure tank with a lifetime warranty covering the tank itself, a metered air-injection control valve for automatic backwash, a bypass valve so you can isolate the system during maintenance without shutting off water to your home, and 10 feet of discharge hose for the drain line. U.S. shipping is free and included in the price. This system ships from Tampa, Florida, and once you order, a sizing confirmation ensures it fits your water conditions and household demand.

Who this size is right for

This is rated for roughly 8 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 bathrooms.

Work out what runs together on a bad morning and size for that figure. Equipment starved of flow does not just run slowly, it stops treating properly.
