Things To Know

3-Year or Lifetime Warranty?
You can order your Inogen with a lifetime or 3-year warranty. Batteries and sieve columns have a 1-year warranty and other accessories have a 90-day warranty.
Can I use the G5 without a battery?
Yes! The Inogen One G5 can be used without a battery as long as it is plugged into a wall outlet with the AC power supply or a vehicle with the DC power supply.
Can I use the G5 while charging?
Yes, the Inogen One G5 can be used while it is plugged into an AC electrical outlet or a DC vehicle outlet. The external power will run the unit and charge the battery at the same time.
How long does it take to charge the batteries?
Can I use the G5 while sleeping?
The Inogen One G5 provides only pulse flow oxygen, which requires sufficient inhalation to trigger the pulse of oxygen. While many oxygen users can use a pulse unit while sleeping, others tend to breathe too shallow or through their mouth while sleeping and are unable to trigger the pulse. These oxygen users would be best served by using a portable unit that has a continuous flow setting.
What is the expected maintenance?
There is an air inlet filter that should be cleaned weekly. The G5 also has replaceable sieve columns that are warrantied for one year and will need replacing about every 15-18 months depending on use and climate.

Product Info

Producing 6 pulse flow settings in under 5 pounds, it's no surprise the Inogen One G5 is the most popular portable oxygen concentrator we offer. The Inogen G5 is the most powerful portable concentrator in its weight class and is the only one that provides up to 6 flow settings among carry-sized portables.

The Inogen One G5 is an excellent choice for oxygen users who require more oxygen than the smallest portable concentrators provide but still want a unit that is light enough for an active life. Speaking of an active life, the Inogen G5 offers two battery sizes. The smaller, single battery will keep your unit as light as possible while still providing hours of oxygen; while the larger, double battery provides twice as many hours of oxygen for longer excursions while no over-burdening you with excess weight.

And don't forget, while you are traveling to your destination you can keep your Inogen G5 running without draining the battery by using the DC power adapter in your vehicle, and once you reach your destination you can use the AC power cord for endless oxygen.

The versatility of the Inogen One G5 and its long-lasting batteries makes it the perfect portable concentrator for living your life free from cumbersome oxygen tanks. It's oxygen on-the-go!
