WSP Air Injection Iron Filter

Are you tired of scrubbing orange stains in your sinks and toilets, only to see them return within days? Or does your hot water carry a persistent rotten-egg smell that no cleaning seems to fix? These are signs your water has iron and hydrogen sulfide, which need more than surface cleaning—they need a change in the water itself.

Stains and Smells That Won't Quit

You probably spend time cleaning bathroom fixtures, kitchen sinks, and even laundry appliances, only to find orange or brown stains reappearing. Shower doors and faucets may have a filmy residue that soap doesn’t rinse away. Sometimes, that sulfur smell, like rotten eggs, shows up when you run hot water. These issues aren’t just cosmetic—they make everyday cleaning a chore that never seems finished.

How Air and Filter Work Together to Improve Your Water

The core of this system is a control head that pulls in a pocket of air without using chemicals. This air reacts with the iron and sulfur in your water, changing them into solid particles that can be trapped in the filter bed below. This process is called oxidation. The system also includes a solenoid valve controlled by a float switch to manage water flow and ensure proper operation. Together, these parts reduce the iron staining and sulfur odor you deal with every day.

The Special Filter Media That Does the Job

Inside the tank is an oxidizing filter bed positioned just below the air pocket. This media targets not only iron but also manganese and hydrogen sulfide—the source of the rotten-egg smell. By turning these dissolved minerals and gases into solid particles, the filter can trap them, preventing the staining and odor before the water reaches your taps.

A Large Tank Built to Handle Your Whole House Supply

The system’s tank holds about 180 gallons of water, which means it’s designed to treat the entire water supply of a typical family home. This size supports steady operation without frequent interruptions for cleaning or filter regeneration. The tank is covered by a lifetime warranty, giving confidence in its long-term durability.

Who This System Is Made For

This air injection iron filter fits well for most single-family homes that get their water from a well or private source with iron and sulfur issues. It handles typical household flow rates and water volumes. If your water has very high mineral levels or you have a much larger household, you may want to look at sizing options to ensure it keeps up with your demand.

What You Receive When You Order

When you buy this system, you get the tank with the air-draw control head, a bypass valve so you can isolate the filter during service without turning off your water, and 10 feet of discharge hose for easy drain connection. The tank itself comes with a lifetime warranty. The electrical controls and valve carry the original manufacturer’s warranty. Shipping is free and included in the price.
