Best Features

All ozone generator models have some important features in common, including a Lifetime Warranty on the ozone cell. These include:

Universal Voltage: No transformer needed, they can be used worldwide.

Efficient Ozone Cells: Our cells are able to produce ultra pure ozone efficiently, making these units almost whisper-quiet. Compare this to loud, inefficient units and the difference is clear. Very low voltage makes it safer for you.

Ceramic Ozone Cells: As ultra pure and ozone-resistant as glass without the burnout potential of glass. Custom made in the United States.

Luer Lock Connections: With Luer Locks, tubing connects securely and won't slip off.

Cold Ozone Production: Cold Corona production means there's no need for cooling fans and no heat buildup that weakens ozone.

Made in the USA: All parts are made in the States. Units are built and hand-checked at our location in Northwest Arkansas.

Premier Support: Because our units are built here, we won't pass you off to other companies for support. We are here to help if you need it.

CE Approved

What's included

Each model comes with an accessory kit that includes silicone tubing with a Luer lock adapter, oxygen tubing with a Luer lock adapter, additional Luer Lock adapters, instruction manual, ug/ml gamma chart, power adapter, check valve, and Luer Lock caps. A host of accessories are available to expand your options.

Years of Research

The O3Elite and O3Arc are the results of years of research and development. We wanted to create a unit that offered ultra pure ozone, was easy to use, had top grade quality control, and a number of features previous customers recommended.

These units are low wattage and low frequency, with cells that won't burn out like glass and do not produce an abundance of heat. They are quiet and efficient, making them ideal for all kinds of ozone applications (if you've ever done an ear insufflation with a different kind of generator, you know how important it is to eliminate the fighter jet-like noise of less efficient machines). When the O3Elite or O3Arc runs, you barely hear it. Because they operate at such low voltage, they are some of the safest ozone generators you can find.

All units come with ceramic ozone cells, Luer Lock connections and universal voltage for worldwide use.

The O3Elite Single and Dual feature dial adjustments. The O3Arc models have preset digital outputs and a flat ozone cell for ultra precise and ultra stable concentrations, as well as a countdown timer. The O3Arc Plus includes a second ozone out port that can be operated by the button or a foot pedal.

Cold Ozone Production

In some machines, ozone production is loud and creates a lot of heat, which can degrade the quality. This is not a problem with the O3Elite or O3Arc. The process makes no excess heat with stable ozone output concentrations at a variety of oxygen flow rates. The O3Elite Mini has simple on/off operation and is adjustable by changing your oxygen source output. The O3Elite Single and Dual and both O3Arc units are fully adjustable using the oxygen source and the ozone generator itself. We provide gamma output charts that allow you to choose the exact settings to get the output you want.


Oxygen Sources

Ozone production requires a high purity oxygen source. We do not include these because needs vary, but we have a range of oxygen options available and can help you find what will work best for you. If you can get a prescription for oxygen, you can use a medical oxygen tank. If you'd prefer a tank but can't get a prescription, you can check your local area for businesses that fill industrial tanks. If you don't want to refill tanks or plan to use a lot of oxygen, you'll want to consider an oxygen concentrator. You can find more information on our Oxygen page.
