Experience the convenience of having your own home oxygen bar with our O2E2 Oxygen Generators, offering top-notch specifications at an affordable price.
The Inspiration Behind “O2E2”
We affectionately refer to our oxygen machines as O2E2® due to their short, roundish design, reminiscent of the Star Wars Robot R2D2®. O2E2 stands for Oxygen + Energy Squared or Oxygen Enhanced Exercise and Rest, as these machines can be used before, after, or during exercise, as well as for enhancing rest during naps or sleep.

Benefits of O2E2 Machines
No Dryness
Say goodbye to dry nasal passages. Our units come with a water bottle that adds moisture to the oxygen, ensuring comfortable usage even for extended periods.
Convenient for Home Use
Skip the trip to the gym and work out in the comfort of your own home. Save time on commuting and contribute to the environment by reducing your carbon footprint.
Cost-Effective
Eliminate the need to spend a dollar per minute at commercial oxygen bars. Your O2E2 will pay for itself after just a few hours of usage, and there’s no need for oxygen bottles.
No Gimmicks!
Our equipment does not require FDA approval as it is designed for recreational use. However, the long-term health benefits are an added bonus.
Built to Endure
Built to industry standards, our supplemental oxygen therapy machines can last between 5 to 10 years with average daily usage of 30-120 minutes.
Loaded with Accessories
Our units effectively separate harmless nitrogen from the air, providing nearly pure oxygen through the tube.
Full Warranty
Enjoy peace of mind with our Three to Five-year warranty for new units and One to Three-year warranty for refurbished units.
Modern Technology
Equipped with onboard computers, our O2E2 units ensure perfect performance at all times.
O2E2 Machine Variants
Choose between two variants of O2E2 Machines based on the flow of supplemental oxygen per minute:
5 LPM (Liter Per Minute) Machines – Available in New and Rebuilt options.
10 LPM Machines – Available in New and Rebuilt options.
Customization Options
Enhance your oxygen machine with our Reservoir Bag and Mega-Flow Mask System, or opt for the complete Turbo Oxygen System for even more benefits. For an introductory trial, you can also purchase just an O2E2 Machine to use with a nose cannula or 1-liter reservoir bag/mask. For optimal results, consider our Oxygen Machine-Reservoir Bag Combos.
