LiveO2 Adaptive Contrast System

LiveO2 Adaptive Contrast 10L System.  Frame is optional.

The LiveO2 Adaptive Contrast (AC) System is our most popular system, patent pending. This system allows you to train with all our exercise usage guides. Our proprietary Adaptive Contrast technology allows you to instantly switch between oxygen concentrated air and oxygen depleted air. This allows you to get better results in less time.

Who it is For

This system is a great fit for any home. It allows you to train using Adaptive Contrast technology in the comfort of your home. With this system you can complete all our exercise usage guides. Because a Standard EWOT system does not have Negative O2 (oxygen depleted air) you can only complete basic exercise usage guides.

We recommend professional athletes and institutions use our Dual AC System.


Adaptive Contrast Dual User System takes up the same footprint as our Standard system. If you upgrade to the 20LPM option you will get two oxygen concentrators.

The AC system uses a more powerful concentrator technology so you can fill a system in as little as 20 minutes (20 LPM Option) or 1 hour (10 LPM Option).


  • Reservoir Height = 7 Feet
  • Reservoir Width = 5 Feet
  • Minimum Floor Space = 7 x 10 foot space for exercise equipment and AC System

Adaptive Contrast Technology

Patent pending Adaptive Contrast (AC) technology gives you access to both oxygen concentrated air and oxygen depleted air. It is the newest generation of our exercise with oxygen technology.

By training with oxygen depleted air your cells quickly create an increased demand for oxygen. When you flip the switch back to higher oxygen air your cells can absorb more oxygen.

Benefits of using AC over Standard (EWOT) reservoir systems include:

  • Increased levels of oxygen in blood plasma and tissues
  • Creating more red blood cells 
  • Expansion of vascular networks
  • Greater energy and cellular voltage
  • Faster recovery/healing/performance
  • Having an AC system also allows you to use all the guides on our website.

    Greatest body hack in past 20 years

    Posted by Michael Sconyers on Sep 12th 2018

    This is one of the greatest body hacks to come along in the last 20 or so years. There is no other way to trick the vascular system to dilate and pulse oxygen into areas that haven't seen ample amounts of oxygen since youth. The trainers and staff really know their facts and can help with personalized protocols to match your specific goals. I might get to busy to lift weights or go for a jog but I will always make time for my Liveo2 session. Thanks Liveo2

    Best investment in my health i have ever made!

    Posted by Polla Pratt on Jul 24th 2018

    I had the Standard LiveO2 system for several years which was awesome and helped me heal a lot. Then I upgraded to the AC system and was totally blown away with my results!!! With the AC system I could immediately push the O2 deeper, way deeper. Immediate healing in my head and gut brains. Immediate substantial reduction in inflammation and increase in all my autonomic body functions. I sleep better, feel better, have a better mental and emotional outlook, and have more energy to do all things I love to do! Best investment in your health that you will ever make! The best I ever feel is after my AC workout.

    Love It!

    Posted by Kathy on Jan 29th 2018

    I have been using the Adaptive contrast system for approzimately 1 month. My enery levels have definitely increased. I sleep much better. I have increased flexibility. I have 3 joint injuries that have bothered me on an off for about 20 years. These have greatly improved, especially my knee. I have also had tinnitus in both ears that has progressively worsened especially over the last 5 years. This has improved to the point that I hardly notice it. My left ear seems unaffected by it now and the right ear is very subtle. I highly recommend this product. Looking forward to seeing how I feel by the end of the year.

    Live O2 Adaptive Contrast System

    Posted by Steve on Aug 7th 2017

    I had major fatigue issues for about 10 years. This has almost eliminated them within about 2 months. I was active (running 3-4 times per week) and my activity level has gone up and I'm not chronically exhausted anymore at the end of the day. I strongly recommend it.
