Inogen One G4 Portable Oxygen Concentrator

The Inogen One G4 Portable Oxygen Concentrator is one of the newest portable oxygen concentrators featuring the latest technology and a 3 year warranty to make sure you have the best user experience. It is Inogen's smallest and lightest portable oxygen device at only 7.2 inches tall and 2.8 lbs.

Inogen Intelligent Delivery Technology - Use it Day and Night

The G4 Portable Oxygen Concentrator provides you with 3 separate oxygen flow settings. The Intelligent Delivery Technology rapidly detects a breath and delivers oxygen in the first 400 milliseconds. 
With flow settings from 1-3, the Inogen One G4 is designed to increase independence for most users 24/7 by delivering oxygen at the start of a breath to ensure users can get what they need in time.

The Intelligent Delivery Technology precisely detects your breathing rate and adjusts the oxygen level to provide accordingly. During sleep, the system provides larger oxygen boluses slowly to correspond with your decreased rate of respiration. If you are doing physical activities, the device will provide quick, smaller bursts of oxygen to satisfy your body's needs.


You can recharge the battery with your car's power port. The unit makes its own oxygen from the air around you, saving you money on buying replacement oxygen tanks. 
The Inogen One G4 comes with a 3-year warranty for the unit and 1-year warranty covers the sieve beds and accessories (battery).
