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

The WSP Whole House Iron & Sulfur Filter - All-In-One, 16x65" is designed to tackle stubborn orange-brown iron stains and the rotten-egg smell of sulfur in your water. It’s built for large homes needing reliable reduction of these common water annoyances across multiple bathrooms and fixtures.

When Guests Notice Orange Stains and That Sulfur Smell

You might not smell it yourself all the time, but the moment a visitor arrives, they could mention that faint rotten-egg smell when running the kitchen tap or shower. Alongside this, orange rings in sinks and toilets or a rusty tint in your glass of water are signs that iron is present. These aren’t just cosmetic annoyances; you’re dealing with dissolved iron and sulfur compounds that impact your daily water use, laundry results, and how often you clean. You might also have noticed that your coffee tastes off or that towels feel rough after washing.

How the Control Head Manages Cleaning on Demand

The system’s control head measures how much water you use and only starts cleaning itself when needed, not on a preset timer. This demand-initiated regeneration helps conserve water and salt, and the automatic backwash cycle flushes out accumulated impurities from the filter media. An air-draw feature pulls in a pocket of air without chemicals, which helps turn dissolved iron and sulfur into particles that the media can catch more effectively. The 1.5-inch porting means the system can handle higher flow rates typical of larger homes without putting strain on your plumbing.

Media Designed to Target Iron, Manganese, and Sulfur

Inside the tank, catalytic manganese dioxide media does the heavy lifting. It works by encouraging a chemical reaction that turns dissolved iron, manganese, and hydrogen sulfide (which causes the rotten-egg smell) into solid particles that the filter can remove. This media works well in aerated water — water that has already been exposed to air — making it suitable for many municipal and well water supplies. Below it, a graded gravel underbed ensures water flows evenly through the media, maximizing contact and efficiency.

A Large 16x65-Inch Tank with Generous Media Volume

The tank is a sturdy 16 inches by 65 inches, holding between 2 to 4 cubic feet of media depending on your water test and flow needs. This size supports service flows up to about 15 gallons per minute, enough to supply several bathrooms in a busy household without pressure drops. The substantial media volume means the filter can work longer between regenerations, reducing downtime and making maintenance less frequent.

Built for Larger Families and Homes With Multiple Bathrooms

This filter suits homes with five or more residents and three to four bathrooms where water demand is high. If your household is smaller or uses less water, a smaller system might be more efficient and cost-effective for your needs. Conversely, homes with even higher flow requirements or more bathrooms should consider scaling up to a larger system to avoid water flow restrictions during peak use.

What You Receive with Your Filter

The system includes a robust tank covered by a lifetime warranty, ensuring the pressure vessel will last as long as you own your home. A bypass valve is provided, allowing you to isolate the filter for maintenance without shutting off water to your entire home—an important convenience that competitors often charge extra for. You also get 10 feet of discharge hose for the drain line, ready for installation by your licensed plumber. The exact media configuration will be confirmed with you after reviewing your water test and flow rate.

Who this size is right for

This is rated for roughly 15 gallons per minute of service flow, which suits a large home - around 5 or more people with 3-4 bathrooms.

The number to match is peak simultaneous demand, not average use. Two showers and a dishwasher at once is the moment that finds an undersized unit, so size for that.
