WSP Whole House Iron & Sulfur Filter - All-In-One, IS-AIO10S

If your water leaves orange-brown stains on sinks and toilets or smells like rotten eggs, the WSP Whole House Iron & Sulfur Filter - All-In-One, IS-AIO10S can help. It reduces iron staining and sulfur odor throughout your home water supply.

The problem you're seeing and smelling

You might notice rusty orange rings inside your toilet tank or brownish spots on your shower doors and kitchen fixtures. Your laundry could come out dingy or towels feel rough even after washing. The smell of rotten eggs, especially when you first turn on your hot water or after water sits still, is another telltale sign. These issues come from iron and sulfur compounds dissolved in your water.

Why this happens in your water

Iron in water comes from natural deposits or corroding pipes, and it changes from clear dissolved iron to solid particles once exposed to air. Sulfur smell comes from hydrogen sulfide gas dissolved in your water—it’s that rotten-egg odor you notice. The best way to confirm this is a water test specifically measuring iron and sulfur levels. This straightforward check tells you if these are behind your staining and odors.

What it costs you to live with the problem

Iron staining can discolor plumbing fixtures and appliances, making cleaning tougher and more frequent. Over time, scale buildup from iron can shorten your water heater’s life and reduce appliance efficiency. Sulfur odors don’t just smell bad; hydrogen sulfide gas can corrode metal pipes and tarnish silverware. Plus, the smell can be embarrassing when guests notice it.

How this system addresses your water issues

This filter uses air-injection oxidation—a process where air is mixed into your water to convert dissolved iron and sulfur compounds into solid particles. These particles are then caught in the filter media and flushed away during automatic backwash cycles. This chemical-free method reduces iron staining and sulfur smell throughout your home water supply.

What this system can handle

The IS-AIO10S is designed to treat both iron and sulfur problems at once, providing whole-house filtration. It works continuously to keep your water free from the orange-brown staining caused by iron and the rotten-egg smell from sulfur. Its automatic backwash keeps the media clean and ready to work without you needing to intervene. The system can handle typical household water usage and conditions, operating efficiently before its scheduled regeneration cycle.

What you actually get

This system includes a pressure tank covered by a lifetime warranty, ensuring the main vessel stands up over time. It comes with a built-in bypass valve so you can isolate the filter during maintenance while keeping water running to your home—a feature others often charge extra for. Also included is 10 feet of discharge hose for the backwash drain line, ready for your plumber to connect.

Is this the right size for you?

The IS-AIO10S fits well for most homes needing to reduce iron and sulfur at the whole-house level. If your water use is exceptionally high or you have very heavy contamination, a larger or more specialized system might be a better fit. Conversely, if your iron and sulfur levels are very low, a smaller or point-of-use filter could be enough. We can help you determine the right size with your water test results.

Living with the system

Once installed, the filter runs automatically. It regenerates by backwashing on a set schedule, flushing out collected iron and sulfur particles to drain. You don’t need to add chemicals or maintain pumps. Periodic check-ups by your plumber ensure everything stays in good working order, and the bypass valve lets you service the system without shutting off water to your home.

What this system won’t do

This filter reduces iron and sulfur but doesn’t address hardness, sediment, or bacteria in your water. If you have those issues, you’ll need additional treatment suited to those problems. This system also won’t remove chlorine or other chemicals if they’re present in your water.
