At just 4.8 pounds the Inogen One G3 is compact, stylish and powerful. Its advanced motor provides Pulse Dose oxygen therapy efficiently and effectively during all phases of daily activity and, for most users, in can even be used at night! Each Inogen One G3 Bundle comes complete with AC and DC cords and integrated batteries to create an ideal solution for active oxygen therapy users 24-hours a day 7-days a week!

Inogen has listened to customers and clinicians to create the ultimate in portable concentrators - providing more oxygen per pound than previous generations without compromising battery life. Compact and easy to carry, The Inogen One G3 will provide you with peace of mind whether for home use, travel, daytime or night use. The stylish look eliminates the feel of carrying medical equipment and it's so small you can carry it with one hand!

With Intelligent Delivery Technology and 5 flow settings, the Inogen One G3 has been verified to deliver oxygen and maintain patient saturations as effectively as Continuous Flow in all modes of use - it makes more oxygen per pound than previous generations yet provides a longer battery life, and it's smaller and lighter.

Inogen's proprietary conserver technology ensures oxygen is delivered within the first 400 milliseconds of inspiration -- where it has the most effect on lung gas exchange. The Inogen One G3 utilizes unparalleled triggering sensitivity to quickly detect a breath and deliver oxygen within this critical period; it can even detect shallow breathing during periods of sleep for successful therapy 24-hours a day.

The Inogen One G3 delivers oxygen in a pulsed dose, called a bolus, each time you breathe in. As your respiratory rate (breathing pattern) changes the Inogen One G3 actively responds to make the best use of oxygen delivery. During periods of activity breathing rates increase so the G3 reduces bolus size to ensure oxygen is not wasted on expiration. During periods of rest and sleep breathing rates typically decrease so the G3 increases bolus to account for the longer periods of inspiration. At 10 breaths per minute, the Inogen One G3 delivers double the bolus size as when the breathing rate is 20 BPM.

Approved by the FAA for use on airlines as well as trains and boats - the Inogen One G3 provides a single solution for daytime and nighttime use eliminating the need to travel with multiple machines - everything you need is in one small package. You can power your Inogen One G3 using a standard wall outlet, "cigarette style" DC outlet found in most vehicles or power your concentrator by battery. Travel has never been easier!

Battery Notes Updated for 2016 InogenOne G3 devices. Batteries will charge whenever sufficient AC or DC Power is available. For battery care guidelines refer to your InogenOne G3 manual. If using multiple batteries, make sure that each battery is labeled (1, 2, 3 or A, B, C, etc.) and rotated on a regular basis. Batteries should not be left dormant for extended periods of time. Store batteries in a cool, dry place. Store with a charge of 40-50%. For optimum performance, once per month: Fully charge the battery then discharge to 10%, then charge back to full.

DEVICE VERSION There are two versions of the InogenOne G3 Portable Oxygen Concentrator. The older version included pulse dose flow settings from 1-4 and had air inlet filters located below the exhaust vents on the side of the concentrator. The newer version, released in early 2016, offers pulse dose flow settings from 1-5 and has air inlet filters above the exhaust vents on the side of the concentrator.

Has Pros and Cons
Written By: Danna , Brownwood, Tx 7/27/2017
This concentrator works really well and easy to operate. It is heavier than I expected especially with the larger battery. The weight causes more exertion and makes my breathing more difficult. The case does not have any place to store the cannula when not in use. I wish they would make a cart for this model like the one for the G2.

Out and About
Written By: I. Bell, Michigan 7/29/2016
I am very happy with oxygen concentrator. It's light weight and lets me have the freedom to go places without hauling one of those big oxygen tanks with me. I can carry it in it's special bag that allows me to carry it like a shoulder strap handbag. It serves my needs for oxygen.

Inogen G3 is a life changer
Written By: Gene, RI 7/9/2016
I have had the G3 for a year and use it 24/7. It has been such a relief to get my old rental concentrator out of the house! It used 3 times the energy of the Inogen, was much noisier and threw of a lot of heat. It was so large that it dominated, both physically and psychically, any room it was in. It's great that I can plug the Inogen into the car so I am not limited if I want to take a longish car trip.

New Found Freedom
Written By: Lois, Hudson 4/29/2016
I absolutely love my portable concentrator. I have my freedom back. I feel like I can live again. With my portable concentrator I no longer have to worry if I have enough oxygen tanks to go somewhere. And no more having to deal with those heavy tanks. With this I can go and enjoy life again. It is awesome.

Compact, easy to use
Written By: CatskillCat, Brooklyn, NY 4/9/2016
I am very satisfied with this concentrator. I needed one for travel, and this turned out to be a very good choice. It isn't heavy, the airport gave me no problems, it is quiet, and does the job.

Written By: Connie , New Hamshire 10/20/2015
First let me say that I purchased my Inogen directly from Inogen. The Inogen 3 is wonderful when it works but not reliable or at least mine has not been. I am on my third in 15 months. What I did not know is that they replace them with refurbished ones. Do not leave home without a back up and now I have no confidence in traveling too far away from home which was the reason for purchasing it in the first place. So buyer beware of there advertising it is not what they say it is. On behalf of Direct Home I have purchased other 02 products and this Company has been great. The reason I'm writing on there site is I have been unable to write a review on the Inogen site.

I love the machine. Pros:able to get out of the house, much easier to use than green tanks, car plug in charger. Cons: It's noisy ~ I don't go to church, library, planes, the strap on the bag has fringed and clip hinges have become to loose causing it to become undone and falling to the ground.

Loud Noise
Written By: George L, Forney, Texas 7/31/2015
The G3 is everything they say and more, it has an extremely loud popping sound when in use. When in church people come up and ask if I am OK, same thing in a theater. I have to fly with oxygen and I am concern that the other passengers will complain. Even in the Casino, the person next to me stares at the machine and ask if it is defective.
