The problem

Iron in well water causes frustrating problems like rust-colored stains on fixtures, laundry, and dishes. It also imparts unpleasant tastes and odors, compromising your water quality and household comfort.

Traditional chemical treatments and salt-based softeners may alter water composition or require frequent maintenance, but often do not fully solve iron staining issues.

The Nelsen AIO Iron Filter System targets dissolved iron effectively, providing your entire home with clean, clear, stain-free water that protects plumbing and appliances.

How it works — the air injection oxidation

To the whole system

The Nelsen AIO Iron Filter uses an advanced air injection oxidation process to remove dissolved iron without chemicals or salt. Inside the single 10" x 44" structural mineral tank, the system maintains an oxygen-rich air pocket at the top of the tank while water passes through.

As water rises through this air pocket, the dissolved iron oxidizes from a soluble form into solid particles. These particles are then trapped within the filter media bed below, effectively filtering iron out of your water supply.

To keep the system operating efficiently, a Fleck 2510SXT control valve automatically performs a daily backwash. This backwash flushes accumulated iron particles to the drain and replenishes the air pocket, sustaining the oxidation process. This self-regenerating cycle requires minimal maintenance, ensuring reliable, chemical-free iron removal for your household.

Frequently asked questions

How does the air injection oxidation process remove iron?

The system maintains an oxygen-rich air pocket at the top of the tank. As water passes through this pocket, dissolved iron oxidizes into solid particles, which the filter media then traps. This chemical-free process efficiently removes iron without salts.

What kind of maintenance does the Nelsen AIO require?

The system automatically performs a daily backwash that flushes out accumulated iron and refreshes the air pocket. Homeowners only need to ensure the unit has power and periodically check the valve and tank for any issues.

Can this system handle all levels of iron in well water?

The system effectively treats typical residential concentrations of dissolved iron. For very high iron levels, a water analysis will help determine if additional pretreatment is needed. We size the system free based on your water results.

Will this system remove other contaminants?

The Nelsen AIO is designed primarily to remove dissolved iron and associated stains. It may reduce some iron-related particulates and discoloration but does not eliminate bacteria, hardness, or other chemical contaminants.

Is salt or chemicals required for regeneration?

No, this system uses only oxygen from the air injection method to oxidize iron. Regeneration happens through an automatic backwash cycle without the need for salt, chemicals, or additives.

Does the system use a lot of water during backwash?

The daily backwash uses water to flush the iron particles from the media. While it does consume some water, the process is efficient and necessary to maintain optimal filtration performance.

Can the system be installed on any well water source?

It is suitable for most residential wells with dissolved iron issues. Prior water testing is recommended to confirm iron levels and other water chemistry factors to ensure compatibility.

How is the system sized for my household?

We provide free sizing based on your water test results and the number of people in your household. This ensures the tank and media capacity match your water usage and iron removal requirements.
