  1. Oxygen Always Reviews

    I was recently put on oxygen and my doctor said I need continuous flow. I cannot lug around these huge tanks let alone travel with them. This machine, although heavier than I like, is a heck of a lot better than the tanks.

  2. Oxygen Always Reviews

    My Inogen does not put out continuous flow and I need oxygen 24/7. This machine is giving me a much better quality of life. – Luke

  3. Oxygen Always Reviews

    I love my new machine! I must have continuous flow when I travel and this is the longest battery life on a setting of 3 available. Thank you! – Nancy

  4. Oxygen Always Reviews

    I wish there was something lighter, but after research I found this is the lightest available. It is easy to use with my CPAP and I travel a lot. – Mary
