Inogen One G2 In Use


I weigh less than your cat.

No more worries about running out of oxygen. No more relying on other people for your oxygen supply. And no more deliveries.

The Inogen One G2 is the first oxygen system ever made to provide an optimal level of freedom for the oxygen user of today. With the Inogen One G2, you don’t need to maintain separate equipment for the home and travel. Best of all, you have no gas or liquid tanks to worry about, because the equipment gets oxygen from the air. Your Inogen One G2 never runs out of oxygen.

The Inogen One G2 is designed to make life easier. It is lightweight enough to carry over your shoulder, and it includes a cart that rolls behind you when you’re out and about. We call it a “polite companion”… and since it’s as quiet as a whisper, most people don’t notice it’s running.

I’m smaller than your coffee maker.

The Inogen One G2 can fit almost anywhere. Now you’ll have space in that room in your home that used to hold a noisy concentrator, oxygen tanks, or a bulky liquid oxygen reservoir. Your Inogen One G2 sits discreetly on the floor, behind a chair, beside the bed, or even over your shoulder. Any way you want it, all your oxygen needs can be accommodated with just one little device—home and away, day and night.

Technology makes the Inogen One G2 lighter and smaller than other models, and it makes it easier to operate. Just push a few buttons. You don’t have to worry about switching regulators or dealing with liquid oxygen freeze. Once you’ve tried it, you’ll ask yourself how anyone could use anything else. Embrace the versatility and simplicity of this wonderful unit and see how it makes life easier.

I can go wherever you want.

You can go home when you want, not whenever the oxygen gauge says you must. Giving you back your freedom is a huge part of the Inogen One G2’s appeal. You can power the unit with a wall outlet, car DC outlet, or keep it running for hours with its included battery. So go jump in the car to go on an errand or take a trip over the weekend to visit your family. You can come and go as you wish without having to worry about switching to another piece of equipment. Or you can take that long road trip you thought you’d never get the chance to take. The Inogen One G2 is designed to follow you everywhere, whether around town, on a cruise, on the road, or up in the air. Where you travel is now your choice!

Speaking of air travel, a lot of airlines now permit you to bring along and operate the Inogen One G2 when you fly. You can take along your oxygen, avoiding the bother of finding oxygen at the airport as well as the expense of using airport-supplied oxygen during your flight. Visit for a list of airlines that currently allow the Inogen One.
