Automatic Iron Oxidizer (AIO): Reliable, Chemical-Free Iron Removal for Well Water Homes

‍

Take Control of Iron in Your Water Without Chemicals or Hassle

Iron in your well water can be more than just a nuisance—it stains fixtures, damages appliances, creates unpleasant odors, and ruins laundry. If you've struggled with orange rings in your toilet or rust streaks in your tub, you're not alone. At Pure Water Choices, we recommend the Automatic Iron Oxidizer (AIO) system: a dependable, low-maintenance, and chemical-free solution designed to remove iron efficiently and automatically.
‍

Why the Automatic Iron Oxidizer (AIO) System?

The AIO is engineered to tackle ferrous (dissolved) and ferric (oxidized) iron, as well as hydrogen sulfide and manganese, using natural air injection and advanced media filtration. It’s the perfect choice for homeowners who want clean, clear, odor-free water—without the use of harsh chemicals.
‍

What Makes It Automatic?

The system features a Clack AIO head with a patented backwashing valve that compresses air into the top of the tank during each cycle. This air pocket naturally oxidizes iron in the water. Once oxidized, the iron particles become filterable and are captured by the filter media. During backwash, the media is cleaned, and the system re-compresses the air pocket—no chemicals or manual intervention required.

How the AIO System Works

1. Air Compression Cycle: The system draws air into the tank during the backwash phase.
2. Oxidation: The compressed air oxidizes iron and manganese as water flows through.
3. Filtration: Oxidized particles are trapped by Katalox Light filter media.
4. Backwash & Re-Aeration: Filter media is cleaned and air pocket is refreshed for the next cycle.

The result is clean, clear water with no staining, foul odors, or taste issues.
