At the top of the list is likely the minimal size and weight of our littlest portable oxygen concentrator, which makes it simple to bring with you out and about. And as long as you have power, the Inogen One G4 provides endless oxygen, because it pulls from, purifies and concentrates the air around you.

The Inogen One G4 is incredibly quiet, allowing you to maintain conversation and hear what is going on around you while receiving your oxygen treatment.
