Inogen Portable Oxygen Concentrators Review
Inogen’s industry-leading warranty is one of the reasons it’s one of our top picks for Best Portable Oxygen Concentrators. Its proprietary Intelligent Delivery Technology delivers oxygen within the first 400 milliseconds of inhalation when oxygen has the most effect on lung gas exchange. Intelligent Delivery Technology received clinical study validation for providing the necessary oxygen levels to most patients during any activity throughout the day and all sleep phases. An Inogen One portable oxygen concentrator can simplify life by replacing all oxygen sources for most people requiring this therapy.
Inogen’s portable oxygen concentrators require no tanks to refill or replace and no regulators. The company offers “oxygen therapy on your terms” because when you switch to an Inogen One, you no longer need to plan your week around oxygen tank deliveries and the insurance, copays and other bills that come with ordering tanks.
The Inogen One portable oxygen concentrator plugs into a wall outlet or DC car outlet for power, or use the rechargeable battery when walking around the house or the town. Inogen makes traveling with a POC much easier compared to traveling with tanks, and both Inogen One models are approved for use onboard all U.S. airlines. Inogen portable oxygen concentrators come with a 30-day risk-free trial (purchase only, restocking fees may apply), and a three-year to lifetime warranty with the bundles discussed below.
- Lifetime warranty (with Freedom Bundle or Package)
- Complimentary clinical services from licensed nurses and respiratory therapists
- An all-in-one solution for stationary, portable, and travel use, day or night
- 30-day free trial (purchase only, restocking fees may apply)
- Insurance may not cover a portable oxygen concentrator

Choosing between Inogen portable oxygen concentrator (POC) models is uncomplicated with Inogen’s small but powerful line of products. The Inogen One comes in two models: the G4 and the G3.
