WSP Whole House Iron & Sulfur Filter - City Water

If your water leaves orange-brown stains on fixtures and laundry, or your hot water smells like rotten eggs, this filter is designed for you. It helps reduce iron staining and sulfur odors in city water, protecting your home from these common annoyances.

The problem

You might notice orange rings around your toilet tank or reddish stains on sinks and tubs. Clothes could come out looking dingy or have a rusty tint, and your shower glass or faucets show a persistent film. When you run hot water, a sulfur smell—like rotten eggs—might be present. These signs point to iron and sulfur in your water supply making everyday use less pleasant and more work.

Why it’s happening

Cities treat water to meet safety standards, but iron and sulfur minerals can still be present. Iron comes dissolved in the water and settles on surfaces, turning them orange or brown. Sulfur, often in the form of hydrogen sulfide gas, causes the rotten-egg smell when water heats up. A simple water test can confirm iron and sulfur levels in your supply and show if these are the culprits behind your staining and odors.

What it’s costing you to leave it

Iron staining gradually builds up on plumbing fixtures, tubs, and toilets, making cleaning harder and less effective over time. The sulfur smell can be off-putting, especially when bathing or cooking. These minerals also use up more soap and detergent to get clothes and dishes clean, and scale from hardness can shorten your water heater’s life. Over time, the orange stains become tougher to remove and can affect the appearance of your home.

How this system fixes it

This filter uses a process called oxidation followed by filtration. It exposes the iron and sulfur in your water to air, turning them into tiny particles that can be caught and held in the filter media. This reduces the iron that would stain surfaces and the sulfur that causes odors. Because it works automatically, it keeps your water clearer and fresher without frequent manual intervention.

What this system can handle

It's designed specifically for city water with moderate levels of iron and sulfur. It reduces iron staining and helps remove the rotten-egg smell from sulfur compounds. The system can handle the typical flow rates of a household, treating water for regular daily use without needing constant regeneration. Compared to smaller filters, this model has a larger capacity and can cope with higher iron and sulfur levels before requiring service.

What you actually get

The system includes a pressure tank covered by a lifetime warranty, so the vessel itself is protected for many years. It comes with a bypass valve included at no extra cost, allowing you to isolate the filter during maintenance without shutting off water to your home. Also included is 10 feet of discharge hose for easy connection to your drain line. These practical components ensure straightforward installation and long-term serviceability.

Is this the right size for you

This filter suits homeowners with typical city water issues involving iron staining and sulfur odors. If your iron or sulfur levels are very high or your household has heavy water use, you might need a larger or specialized system. Conversely, if your water has only faint traces, a smaller filter could suffice. We recommend sending us your water report and household details so we can confirm this system matches your needs exactly.

Living with it

Maintenance involves periodic backwashing and occasional media replacement, depending on your water quality and usage. The included bypass valve makes servicing simple without interrupting your water supply. While the control valve and electronics have their own warranty terms, the main tank’s lifetime warranty adds assurance. Maintenance costs are modest and mainly involve replacing filter media after extended use.

What it won’t do

This system does not soften water by removing hardness minerals like calcium and magnesium, so it won’t stop scale buildup entirely if your water is hard. It’s focused on iron and sulfur reduction only. For hard water issues, a separate water softener would be needed. It also doesn’t remove other contaminants such as bacteria, sediment, or chemicals that require different treatment methods.
