WSP Whole House Iron & Sulfur Filter - Automatic Air-Injection

When the dishwasher door opens and you see orange-brown streaks on your glasses, or the first shower of the day carries a faint rotten-egg smell, your water is showing signs of iron and sulfur. These issues cause stains and odors that don’t just disappear by themselves.

Noticing Stains and Smells in Everyday Water Use

That orange-brown ring inside the toilet tank, rust-colored streaks on sinks and tubs, or a metallic taste in your drinking water are clear signs of iron in your supply. Alongside that, a sulfur odor—like rotten eggs—often comes from hydrogen sulfide gas dissolved in the water. These problems turn routine tasks like showering, washing dishes, or brewing coffee into frustrating experiences. You might find yourself scrubbing stains repeatedly or dealing with a lingering smell that no amount of cleaning seems to fix.

How the Control Head Manages Water Treatment Automatically

At the heart of this system is a control head that uses a timed schedule to keep your filter working efficiently without your intervention. It automatically initiates a backwash cycle, lifting and rinsing the media bed to flush out trapped iron and sulfur compounds. An air-draw feature pulls in a small pocket of air into the system to oxidize iron and hydrogen sulfide chemically—without adding chemicals. The 1.5-inch porting ensures a steady flow for your household needs, handling up to about ten gallons per minute.

The Media That Targets Iron and Sulfur in Your Water

Inside the tank, catalytic manganese-dioxide media and manganese greensand work together to reduce iron, manganese, and hydrogen sulfide. These materials oxidize dissolved metals and sulfur compounds, turning them into particles that can be trapped and flushed away. A graded gravel underbed supports the media and ensures an even flow, preventing channeling and maintaining consistent treatment performance.

Tank Size and What It Means for Your Water Use

The filter comes with a 10" by 44" tank, a size well suited to typical family homes with two to three bathrooms and three to four people. This tank holds enough media to treat your water steadily at daily flow rates without frequent regeneration. The design balances compactness with capacity so that it fits well in most utility spaces while handling the demands of an average household comfortably.

Who This Filter Fits Best and When to Consider Alternatives

This unit suits average-sized homes facing noticeable iron staining and sulfur smells but should be matched to your household size and water usage. If you have a larger home, higher flow demands, or more severe water problems, a larger system or additional treatment might be needed. Conversely, smaller households or properties with lower flow rates might be better served by a more compact option.

What Comes with the System and How to Proceed

The WSP Whole House Iron & Sulfur Filter includes a lifetime warranty on the tank—the pressure vessel itself is covered for life. The control valve and electronics carry their own manufacturer warranties. You get a bypass valve included, so you can isolate the system and keep water running to your home during any maintenance. Also included is 10 feet of discharge hose for the drain line.

Who this size is right for

This is rated for roughly 10 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 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.
