Inogen One G3 Portable Concentrator Product Overview Back to top
The Inogen One G3 is currently one of the smallest, lightest portable concentrators that produces medical oxygen and offers an extremely long lasting battery. The oxygen machine was designed to provide users with the highest level of independence. It has, all the same, features as its predecessor, the Inogen One G2 but it is smaller in size, lighter in weight and produces more oxygen per pound. It is a portable concentrator that you can hold in one hand and does not require a rolling cart. Forget about your oxygen tanks, this unit never needs to be refilled so you will never have to worry about oxygen running out!
The Inogen G3 weighs less than 5 pounds with the 8 cell battery and 5.7 with a 16 cell battery. The G3 unit comes with a carry bag that can be worn over your shoulder for easy transportation. The batteries were made and tested to be long lasting. The 8 cell battery can last up to 4 hours at a setting of 2 and the 16 cell battery can last up to 7 to 8 hours on a setting of 2 as well. The rechargeable batteries also have a quicker than normal recharge time at around 4 hours with the 8 cell battery and on the average of 6 hours for the 16 cell battery. The dimension of this unit are only 7.25 inches tall, 3 inches wide and 8.75 inches long; making it one of the smallest sized concentrator ever produced.
It is a pulse dose portable concentrator that operates on setting from 1 to 5 with oxygen concentration levels at around 90%. The machine is barely noticeable at only 39 decibels. It is so quiet that you can use it in a library or church without hearing it. It also features an easy to read LCD screen that displays flow settings and battery life.
It is FAA Approved for usage during flights and can be used on most cruise ships and buses. This makes it as a truly ideal solution for travel far and near!

This unit is one of the best investments I've ever made! Worth every penny! I take it everwhere. The only improvement I could suggest is to be able to change it to continuous flow while you're at a movie. Once the sound comes up you can't hear it.l

Great little portable concentator!
I've only had the Inogen for a short time soon far but it's the best I've used.

Rented then bought
When I went on vacation last year, I rented the G3 rental with two 16 cell batteries. I liked it so much that when I got back, I decided to buy it. I was impressed by how long the batteries lasted, and how quiet it was, among other things!

Easy and efficient
This is perfect for traveling in every way. I used to have an older portable oxygen concentrator that didn't charge up as fast, and was much heavier. I'm glad that I can get the oxygen, 4 LPM pulse dose from a smaller and more efficient concentrator.

i think it is great! I go out with it for long periods of time. One of the best ones i have had.
Review by Chris I on 4/23/2015
It's so nice to be able to go out while still getting the oxygen I need. I hated being confined to my house, even when I didn't want to go anywhere. I take my G3 everywhere and I'm very pleased with its performance.

Keeps me going
This concentrator works great for me, but what I really love is the long battery life. I use the 16 cell battery because I use it for many hours each day. Keeps me off the couch and out of the house most of the time.
Review by Bill on 12/8/2014
I researched and then confirmed by looking at a friend's unit before ordering. I was convinced this is the lightest with good battery life. After using it for a month, I am convinced I made the right decision to chose this unit. It has performed well, is easy to carry and has very good battery life.
