INOGEN ONE is the first oxygen system designed to provide unparalleled freedom for the active oxygen user. With the INOGEN ONE, you'll no longer need separate pieces of equipment for home, portable, or travel use. Best of all, because it gets oxygen from the air around you, there are no gas or liquid tanks to fill. That means your INOGEN ONE will never run out of oxygen.

INOGEN ONE is made to make your life easier. It's light enough to carry over your shoulder, and it comes with a cart to roll behind you when you're on the go. We like to think of it as a "polite companion"... and since it's whisper quiet most people don't know it's running.

INOGEN ONE will fit virtually anywhere. Now you can reclaim that room in your home occupied by a noisy concentrator, spare oxygen tanks, or a large liquid oxygen reservoir. The INOGEN ONE can sit discreetly at your feet, behind a chair, next to the bed, or over your shoulder. All of your oxygen needs can be met with this one small device - day or night, home or away.

Technology not only makes the INOGEN ONE smaller and lighter, it makes it easier to operate too. Just a couple of buttons. That's it. There are no regulators to switch or liquid oxygen freeze-ups. Once you try it, you'll wonder why anyone would use something else. Embrace the simplicity of the INOGEN ONE and see how  it can make your life easier.

Many airlines now allow you to use the INOGEN ONE when you fly. Now you can take your oxygen with you, avoiding the hassle of arranging oxygen at the airport  with your provider and the expense of airline-supplied oxygen during flight.
