Inogen One G3 Portable Oxygen Concentrator System

  • $2,295.00


The Inogen One G3 works all day so you can play. At under 6 pounds, the G3 can give you up to 10.25 hours of battery-powered oxygen* with a setting range of 1-5. Say good-bye to the days of portable tanks and having to make expensive, complicated travel arrangements. The G3 puts you back in charge of your schedule and your life!

The G3 is clinically validated to be used 24/7, so it can supply all the medical oxygen you need at home or on the go! Its easy-to-read LCD screen always shows you how much battery life you have and when you’re close to running out, you can plug into a wall (AC) or car (DC) outlet and use the concentrator while charging your battery at the same time!
