    The Inogen G4 Portable Oxygen Concentrator is one of the smallest and lightest portable oxygen concentrators ever sold with a setting capability of 1-3. It also stays true to the Inogen line by providing extremely quiet operation. You might forget that your carrying it around. On top of all the comfort features the Inogen G4 boasts the highest oxygen output per pound (unit weight) of any portable oxygen concentrator on the market.

    It is FAA approved for airline flight. The easy to swap batteries make long flights or outdoor activities away from power sources a non-issue.

    As with the G3 the Inogen G4 allows for easy replacement of your sieve beds. This allows you to have much less down time when your G4 needs maintenance. No need to send it back to the manufacturer for regular maintenance issues.

    The Inogen G4's size, durability, weight, and performance make it an excellent choice for anyone needing oxygen on the go.
