Introducing the next innovation to portable oxygen delivery: The Inogen One G4, capable of full 24/7 oxygen delivery in an unbelievably small package! Offering 1-3 flow settings, the Inogen One G4 is one of the smallest, lightest and quietest units available to the oxygen user today.

THE INOGEN ONE G4 SYSTEM

The Inogen One G4 is the smallest portable oxygen concentrator we offer, weighing just 2.8 pounds. Because it is so incredibly portable and lightweight, the Inogen One G4 is easy to take with you wherever you go, allowing you to get oxygen anytime, anywhere, without disrupting your life. Our smallest portable oxygen concentrator is only about the size of a large coffee cup, measuring 7.2 inches tall, 5.91 inches long and 2.68 inches wide, so you can pop it in its carrying case and easily sling it over your shoulder. Whether you use the Inogen One G4 at home or on the go, you will discover how convenient and transportable it is, so you can live a full and active life while getting the oxygen therapy you need.
