Air Injection Oxidation (AIO) Systems
Eliminate Sulfur Smells, Iron Stains, and Manganese Problems Without Chemicals
If your water smells like rotten eggs, leaves rust-colored stains on fixtures, or causes black staining in sinks and toilets, you’re not alone. These are common well water issues throughout Indiana. The good news is that they can often be solved without adding chemicals to your water.
At C and J Water, we install advanced Air Injection Oxidation (AIO) systems that remove hydrogen sulfide, iron, and manganese while improving the taste, odor, and appearance of your water.

What Is an AIO System?
An Air Injection Oxidation system uses a pocket of compressed air inside the treatment tank to naturally oxidize contaminants found in well water.
As water passes through the air chamber, dissolved iron, manganese, and sulfur compounds are converted into particles that can be filtered out before they reach your home.
The result is cleaner, fresher water without the need for constant chemical treatment.
Signs You May Need an AIO System
You may benefit from an AIO system if you notice:
- Rotten egg odors in your water
- Orange, red, or brown staining on sinks, tubs, and laundry
- Black stains on fixtures or toilets
- Metallic tastes in drinking water
- Discolored water from faucets
- Water quality issues common with private wells
An Air Injection Oxidation (AIO) system is a whole-home water filtration system that removes iron, manganese, and hydrogen sulfide (rotten egg odor) from well water. It uses air to oxidize these contaminants so they can be filtered out before the water enters your home’s plumbing. The result is cleaner, better-smelling, better-tasting water without the continuous use of chemicals.
An AIO system is designed to solve many of the most common well water problems, including rust-colored stains, black manganese stains, rotten egg odors, metallic tastes, and discoloration. It also helps protect plumbing fixtures, appliances, and water heaters from mineral buildup caused by iron and manganese.
An AIO system creates an air pocket inside the treatment tank. As water passes through, oxygen reacts with dissolved iron, manganese, and hydrogen sulfide, converting them into particles that are trapped by specialized filtration media. The system automatically backwashes to clean itself and maintain peak performance.
Yes. If your well water smells like rotten eggs because of hydrogen sulfide gas, an Air Injection Oxidation system is one of the most effective treatment options available. It removes the odor before the water reaches your faucets, showers, and appliances.
Yes. An AIO system is specifically designed to remove dissolved iron that causes orange or brown staining, metallic tastes, and rust buildup. The right system size depends on your home’s water chemistry, which is why professional water testing is recommended before installation.
No. An AIO system removes iron, manganese, and sulfur, but it does not soften water. If your home also has hard water, pairing an AIO system with a water softener provides complete whole-home water treatment and better protection for your plumbing and appliances.
No. Most Air Injection Oxidation systems treat water using oxygen and specialized filtration media instead of continuously adding chlorine or other chemicals. This makes them an effective, low-maintenance solution for many well water applications.
A quality Air Injection Oxidation system can often last 15 to 20 years or more with proper maintenance. The filtration media may eventually need replacement, depending on your water quality and water usage, but the system is designed for years of dependable performance.
If your well water leaves rust stains, black stains, has a rotten egg odor, or contains elevated iron or manganese, an AIO system may be the ideal solution. A professional water analysis is the best way to determine the right treatment for your home’s unique water conditions.
Every well is different, and so is every water treatment solution. At C and J Water, our Certified Water Specialists test your water, explain your options, and recommend a system based on your home’s specific water quality—not a one-size-fits-all approach. We help Central Indiana homeowners enjoy cleaner, healthier water with professional installation and ongoing support.
