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 dimensions 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 a truly ideal solution for travel far and near!
The Inogen One G3 Starter Package includes the Inogen G3 Unit, 8 cell battery, AC power supply, DC power cable, carry bag, cannula, and manual. Please ask about our different Inogen G3 Packages if you require more batteries or accessories.

We were looking for portable oxygen concentrator for my mom from last 4 months and could't find good company that can explain all our questions, then we found Oxygen Concentrator Store and sales person, Avery helped us throughout the process from selection to placing order. He took a lot of time to go and verify and explains each details to me. I may find $100 cheaper from somewhere else but I won't find this kind of great service and confidence to purchase.

I have had the iogen g3 for over a year and it has allowed me to get my life back.
The unit worked right out of the box, never had a problem. The batteries work great and they last all day. The people at the Oxygen Concentrator store like Carlos Arroyave, and Nick at customer service are great. I will all ways recommend you guys

Great for travel and errands
I have the inogen g3 and it is the best purchase I have ever made. Started having some error alarms that resulted in the machine needing to go for repair. It has been very difficult to get timely information from Oxygen Store. Every person i talk to gives me a different story. Since its warranteed maintenance, it should be a simple process. So basically the sales staff is great but the repair staff is lousy. Hoping it all works out.

I waited for years until I could finally get my G4 portable oxygen unit and I absolutely love it although I won’t be mountain climbing anytime soon there’s not much I can’t do that with my oxygen from in a Jen thank you so much for making a machine just for me

I travel continually and this machine allows me to travel the world! Have used it in Europe, Asia, South America,Australia and in all parts of the USA. It works fine using both 120 and 240 charging. Easy through security and lightweight.

Great, reliable and backed by a good company. Let's me be free to travel and participate in various events I would miss otherwise. Mine is almost three years old. I would be lost without it.
Review by Ladyvet17 on 2/23/2017
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.
Review by Rick on 6/17/2015
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!
Review by Terri on 6/3/2015
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.
