WSP Whole House Iron & Sulfur Filter - All-In-One, 16x65"

If your water leaves orange-brown stains on sinks and toilets or your showers carry a rotten-egg smell, the WSP Whole House Iron & Sulfur Filter - All-In-One, 16x65" is designed to help reduce those issues throughout your home’s water supply. It’s a whole-house filter that targets iron and sulfur problems before the water reaches your taps.

The problem you’re living with

You notice orange rings in the toilet tank, brown streaks on shower doors, or rusty spots on dishes. Maybe it’s the smell—the unmistakable rotten-egg odor when you run hot water or showers. These signs point to iron and sulfur in your water supply, turning everyday tasks into constant cleanup and discomfort.

Why it’s happening

Iron and sulfur minerals naturally occur in many water sources, especially well water. Iron shows up as tiny particles or dissolved compounds, which oxidize when exposed to air, forming those telltale orange-brown stains. Sulfur, often in the form of hydrogen sulfide gas, creates that rotten-egg smell. A simple water test for iron levels and sulfur smell confirms these are the culprits.

What it’s costing you to leave it

Iron stains build up over time, leaving fixtures and laundry looking dull or discolored. Sulfur odors make your water unpleasant for bathing and cooking. Both problems can increase how much soap and detergent you use because they interfere with cleaning. Iron deposits can also shorten your water heater’s lifespan by coating heating elements with scale, forcing the appliance to work harder and use more energy.

How this system fixes it

This filter uses air injection to add oxygen into the water, which turns dissolved iron and sulfur into solid particles. These particles then get trapped by the filter media inside the tank. The system backwashes periodically, flushing those particles down the drain to keep the filter bed clean and working efficiently. The process relies on oxidation—the reaction of oxygen with contaminants—to reduce what causes stains and smells.

What this system can handle

The 16x65" size is a robust whole-house solution. It deals effectively with iron, sulfur, and even manganese, provided the right filter media is chosen. It supports service flow rates up to around 15 gallons per minute, suitable for most busy homes. The system’s air-injection process delays regeneration when water is flowing, which helps protect your drain line and conserves water during backwash cycles. Because it ships without media, it can be matched precisely to your water’s needs, whether that’s Birm, Centaur, or Katalox-Light® media for different levels of iron and sulfur.

What you actually get

This system includes the 16x65" mineral tank with a lifetime warranty on the pressure vessel, meaning the tank itself is built to last. It features a corrosion-resistant composite control valve designed to withstand humid environments without corroding over time. A bypass valve comes standard, letting you isolate the filter for service without shutting off water to your home. You also receive 10 feet of discharge hose for the drain line, making installation easier for your plumber. The control valve and electronics carry their own manufacturers’ warranties.

Is this the right size for you?

This model suits homes with moderate to heavy iron and sulfur issues and typical family water use, including multiple bathrooms and large kitchens. If your household water demand is lighter or your iron and sulfur problems are less severe, a smaller unit might be more appropriate. For very large homes or commercial settings with higher flow needs, you’d look at larger or multiple units. We help you figure out the right fit when you request a quote.

Living with it

Maintenance involves adding the appropriate filter media based on your water analysis and having your plumber set up the system. The system backwashes automatically on a metered schedule, so you don’t have to manage that daily. Periodically, your plumber should inspect the bypass valve and discharge hose for wear. Realistically, media replacement depends on water quality but often runs several years before needing attention. The lifetime warranty on the tank gives added peace of mind about long-term durability.

What it won’t do

This system helps reduce iron, sulfur, and manganese, but it does not soften hard water minerals like calcium or magnesium. If you have hard water causing scale buildup and soap efficiency issues, you’ll need a water softener in addition to this filter. It also does not remove bacteria, sediment, or other chemical contaminants; separate solutions address those concerns.
