The Dual is ideal for:
The O3Elite Dual is our powerhouse ozone generator capable of performing any type of ozone therapy.
- Insufflation: ear, rectal, vaginal
- Topical: cupping, skin application
- Water: drinking water, sanitation
- Inhalation: ozonides through oil
- Body: full body ozone sessions
- High Heat: Ozone Saunas
- Dental: compatible with dental accessories
- Any other ozone application
If you want to offer the full range of ozone uses, you need an ozone generator that can provide a wide range of outputs, including higher rates that can be used with high heat.
The O3Elite Dual has two ozone cells capable of producing ozone up to 100 gamma. This covers it all: insufflations, saunas, ozonating water, cupping, full body ozone, breathing ozonides through oil, and anything else you may need. If you don't plan to use high-heat applications, you can reduce your costs by choosing the O3Elite Single.

Great Ozone Generator!
"I have had one of these for 4 years and just purchased another one. The O3Elite is a very powerful system and I can vouch for the calibration. I use it for everything from a sauna down to nasal insufflations. I use it to bag limbs and every kind of insufflation. I love this little unit."
- Dr. William Coan
Best machine I have ever owned
"I have been working with ozone since 1994. I have had this machine for over 10 years and it is amazing. Easy to use and this company is very supportive in terms of answering questions and providing instruction. A great investment, well worth the money."
- Luanne P.
Love my new O3 machine!
"I bought my 1st [generator] in 1996. It was primitive but probably saved my life more than once. I bought a second one from one of the other currently popular companies but found it too weak and of questionable quality. I love the new Promolife Dual. Simple, powerful and affordable!"

Frequently Asked Questions
How safe is the O3Elite Dual?
Short Answer: The O3Elite Dual operates at 1.5 amps with low-voltage ceramic cells; no high-voltage glass components that can fail or burn out. All parts are USA-manufactured and individually tested before shipping.
Due to our rigorous testing and manufacturing processes, we can confidently state that the O3Elite is the quietest and safest ozone generator available.
Why is Cold Ozone Production important?
The O3Elite Dual Ozonator works with either an oxygen concentrator or an oxygen tank (both sold separately).
It uses Cold Ozone Technology with ceramic cells, so it produces ozone with virtually no heat and stays cool even during extended use. This gives you stable, consistent ozone concentrations that do not drop over time.
You can easily create precise ozone levels up to 100 μg/ml by combining the generator’s output settings with different oxygen flow rates from your oxygen source. We include a simple, easy-to-read chart that shows exactly how to set your machine for the gamma (concentration) level you want.
Why ceramic cells are better:
- Stronger and more efficient ozone production
- Uses minimal voltage
- Extremely quiet operation (almost silent)
- No excess heat
Machines that use glass cells often get hot, make loud noise, and are much less suitable for ozone therapy.
This design gives you reliable, quiet, and precise ozone output that’s ideal for home or professional ozone therapy.
How do I find the right Oxygen Source?
In order to create quality ozone, you need a high purity oxygen source like an oxygen tank or an oxygen concentrator. When oxygen comes into the unit, the O3Elite transforms it from two molecules (O2) to three (O3). After a short period of time the third molecule breaks off and does the work in ozone therapy. To see your options, you can visit our Oxygen page. It will show you the options and help you choose what's right for you.
If you have questions, please let us know.
Shipping Note: If adding an oxygen concentrator to your order, it may take one to two weeks to ship the concentrator.
Which ozone generator is right for me?
The O3Elite Single has an adjustable dial and creates ozone up to 70 ug/ml, while the O3Elite Dual has two ozone cells and adjustable dials to create ozone up to 100 ug/ml. The Mini has one button operation and produces ozone up to 70ug/ml. The Mini and the Single are ideal for most ozone applications. If you want more variability in output, consider the Single. If you plan to do ozone saunas or want to ozonate oil and water more quickly, you'll want to look at the Dual. For a complete guide, have a look at our Ozone Generator Comparison.
What more can you tell me about the O3Elite Dual?
The Dual creates stable ozone up to 100 ug/ml (gamma). This allows you to do any ozone applications you wish including ozone saunas, insufflations, ozonating water, breathing ozone bubbled through oil, using ozone syringes, topical ozone, and more. With two cells, you get even more flexibility to expand your ozone routine any way you see fit.
Designed with a lifetime of use in mind
The O3Elite was created after years of working with ozone generators from other manufacturers. We wanted a unit that was easy to use, provided ultra high quality ozone, with a number of important features, and superior quality control. The O3Elite exceeded even our high expectations. The Dual creates stable ozone up to 100ug/ml (gamma). Other units are available.
The O3Elite is the next generation of low-wattage, low-frequency ozone generators. Unlike dangerous high voltage glass cell generators, the O3Elite will never burn out, is very quiet, and operates cool so the ozone is not destroyed by heat (this provides a more stable ozone output; you might want to see this article: Glass vs. Ceramic: What's Best for Ozone Generators?). Glass cells generate a tremendous amount of heat which compromises the quality of ozone. The O3Elite comes standard with Luer locks, universal worldwide voltage, wall mounts and cleanable cells.
What ozone outputs are possible with the O3Elite Dual?
The Dual comes with two charts, one with Boost engaged and one without. Simply match the Oxygen rate on the left with the Dial settings to find the output. For instance, in the Cell 1 without Boost chart, if your oxygen is set to 1/2 LPM and your dial is set to 5, you will produce 8 ug/ml (also known as gamma).
