Inogen One G4 Oxygen Concentrator


Introducing the next innovation to portable oxygen delivery: the Inogen One G4, capable of full 24/7 oxygen delivery in an unbelievably small package!

The Inogen One G4 is officially the smallest and lightest portable oxygen concentrator ever released by Inogen. Weighing in at 1.27kg with the single battery, the Inogen One G4 is more than 40% lighter than the Inogen One G3 and it's about half the size! It even weighs less than some of the most commonly used portable oxygen tanks.

For such a small unit, the Inogen One G4 is incredibly powerful. It's a pulse flow delivery system which means it does not offer continuous flow, but it offers settings 1-3. It is equipped with Inogen's standard Intelligent Delivery Technology to ensure the unit detects your breath to delivery your oxygen with incredible accuracy. The G4 is the smallest and lightest unit in its class and you don't sacrifice functionality or battery life for the small size.
