Inogen One G3 Portable Oxygen System

Independence. That’s what oxygen users really get from an Inogen G3 portable oxygen concentrator. At home and on the go, the Inogen One G3 achieves the independence that you’ve been missing – not just for running errands or short trips out of the house, but real independence – true spontaneity.

Take off on a moment’s notice, without having to watch the clock or guess how long your oxygen supply will last. The Inogen One G3 is not simply a stationary device, not simply a portable one.
