Inogen One portable oxygen concentrators have long been praised for being some of the quietest machines on the market. The G4 continues this tradition and adds in some amazing new benefits, like dropping 40% in size from previous models! At merely 2.8lbs this machine is easy to transport, so you can stay on the go!

Capable of providing 24/7 oxygen conveyance, the G4 dispenses pulse dose oxygen therapy using Inogen's patented Intelligent Delivery Technology. Proprietary conserver technology contained within the Inogen One portable oxygen systems ensures oxygen is delivered within the first 400 millisecond's of inspiration where oxygen has the most effect on lung gas exchange. The Inogen One oxygen systems utilize unparalleled triggering sensitivity to quickly detect a breath and deliver oxygen within this critical period.

Small enough to rest on your lap during a movie or car ride, light enough to accompany you on an outdoor adventure or trip to the store, the G4 is a wonderful oxygen companion for those on the go. Available in Single and Double Battery Bundles, the G4 is one of the smallest, lightest, and quietest portable concentrators on the market. Single batteries can provide up to 2.7 hours of use, and Double Batteries offer a remarkable 5 hours. Comparable in size to a small purse or shoulder bag, this portable concentrator is discreet and tastefully designed.

Monitor your oxygen therapy anytime and anywhere with Inogen Connect - the free mobile app available for Inogen One G4 & Inogen One G5. With Inogen Connect you can check your battery life, monitor column life status, make sure your concentrator is operating correctly and much more. The Inogen Connect App is available for download on the App Store or Google Play. ^literature~

    I'm thrilled to have this unit. I've not been getting out as much a I would have liked d/t the weight of the other heavier O2 concentrator hurt my shoulder and lower back. My insurance would not cover this lighter unit so I purchased myself and was well worth the investment.

    Just received the unit and had a little problem getting it going but with the manual I succeeded. Now I need a time to use it to see if I really like it.

    Okay, it's not fluffy but it IS soooo small! I'm used to my tanks and I still use them sometimes but now that my son bought me the Inogen G4 I'm not sure I'll need the tanks for much longer. I can carry my concentrator with two batteries and an extra cannula and have a great afternoon out with the girls. I love it.
