WSP Whole House Iron & Sulfur Filter - All-In-One, C-Series

If your water leaves orange-brown stains on sinks, toilets, and laundry, or if your showers carry a rotten-egg smell, you’re dealing with iron and sulfur in your water. This system helps reduce those issues for your whole house.

The problem you’re facing

Maybe you’ve noticed an orange ring around the toilet tank, rusty spots on your fixtures, or laundry turning dingy. Your hot water might smell like rotten eggs, a sign of sulfur compounds. These problems don’t just look or smell bad—they make everyday cleaning harder and affect how your water feels and tastes.

Why it’s happening

Iron and sulfur occur naturally in well water and sometimes in surface water. The iron shows up as rust-colored particles that build up and stain. The rotten-egg smell comes from hydrogen sulfide gas, which is sulfur mixed with water. The sure test? A water sample analyzed for iron and sulfur levels by a local lab or water specialist will confirm it.

What it’s costing you to leave it

Iron stains don’t just wash away easily—they build up on fixtures, sinks, and in appliances. Sulfur odors can make everyday water unpleasant, affecting your coffee, cooking, and bathing. Over time, these minerals can shorten your water heater’s life and cause appliances to work harder, using more energy and soap to get things clean.

How this system helps

This filter uses air injection to oxidize iron and hydrogen sulfide, turning them into particles you can filter out. In simple terms, it adds air to the water, which causes iron and sulfur compounds to form solid bits. These bits get trapped in the filter’s media and flushed out during cleaning cycles, reducing staining and smell throughout your home.

What this system can handle

The WSP Whole House Iron & Sulfur Filter - All-In-One, C-Series is designed for smaller homes or moderate iron and sulfur levels. It manages dissolved iron and hydrogen sulfide effectively, helping clear up rust stains and unpleasant odors without using chlorine or other chemicals. The 10" x 44" tank size is compact but capable, balancing space and capacity. It’s built to handle daily use with programmable cycles that save water by controlling when and how the system cleans itself. You won’t need to worry about frequent backwashes or wasted water.

What you actually get

The system includes a durable black polyglass mineral tank covered by a lifetime warranty on the tank itself. The control valve, which manages air injection and cleaning cycles, comes with the manufacturer’s standard warranty. You also get a bypass valve included, which lets you isolate the system while still running water to your home during maintenance or service. Ten feet of discharge hose for the drain line is part of the package — ready to connect when your plumber installs the system.

Is this the right size for you?

This unit suits smaller homes or those with lower to moderate iron and sulfur levels. If your household is larger or your iron and sulfur concentrations are high, you may need a bigger system with a larger tank and higher flow capacity. The WSP team can help confirm the right size once they know your water conditions and ZIP code.

Living with it

The system runs mostly on its own, with programmed air and backwash cycles that keep the media clean and effective. Routine maintenance might include occasional checks of the control valve and making sure the drain line remains clear. Your plumber can handle any service the system needs, using parts still available years down the line. The bypass valve makes servicing straightforward, so you won’t lose water access during upkeep.

What it won’t do

This filter reduces iron and sulfur issues but does not soften hard water minerals like calcium or magnesium. If hard water is also a problem, a separate water softener would be necessary. It doesn’t remove bacteria, viruses, or chemical contaminants either, so it’s not a complete purification system.
