Weighing just 2.8 pounds, our Inogen One G4 model is our smallest portable oxygen concentrator. If you prioritize portability over all other features, this is your model.
The Inogen One G5, is a bit heavier at 4.7 pounds, a bit smaller than your standard 8.5” x 11” coffee table book1, offers more flow settings, and our longest battery time. With 6 flow settings, 3 more than the Inogen One 4, the Inogen One 5 is our most versatile POC for patients with higher oxygen requirements. Still, if size and weight are among your top considerations, the Inogen One G4 is likely to be your top contender.
Portable Oxygen Concentrator Comparison: Flow Settings and Use
Your oxygen prescription plays heavily into which Inogen One model best meets your oxygen needs. If you need a variety of different flow settings throughout the day, the Inogen One G5 offers six pulse dose flow settings—giving you the most versatility.
