The operation is just like you know it from the portable oxygen concentrators of Inogen. Logical, simple and with certainty.

The Inogen One G4 is a pulse flow system, like all the other devices of Inogen. With 3 settings en powerful device, suitable for most people that use portable oxygen concentrators.

But, if weight and size are not decisive, we advise you to consider the Inogen One G3. Because the G3 has 5 settings it can still be used if your demand grows over the time in the near future. Besides, the battery life of the G3 batteries is longer because of the larger size of this battery.
