easy to use and very effective
By Sandra S.
Since I received my Inogen oxygen compressor, my whole oxygen support has improved! The unit itself is easier to carry and operate. The battery indicator display, the L/minute and alarm are easily readable. Plus it's compact design makes for a comfortable, manageable carry option. I would definitely recommend this product to anyone, and I have!

They are great. We had a problem with our Inogen G5. Called customer service. They had us try a few possible fixes. None worked so they immediately shipped a new machine to us. We are extremely happy we purchased an Inogen!

I truly enjoy the portability of this unit. It is light enough that I carry it in a mesh backpack and can be at work doing my normal activities. I get so many people who stop me and ask about my Inogen and I always tell them how much I love my unit and the independence it has afforded me.

ease of use and accessibility is worth the cost associated with The Gen 3 and the Gen 5 : I have and use both. The Gen 5 is smaller and more compact and seems to do the same job as the Gen 3. I use the Gen 3 more than the 5 because I have had it longer.

I'm very satisfied with my Inogen. When I need it's ready I was recency release from hospital after having influenza A. I'm now using oxygen and when I need a backup I know that I can depend on my G4. Paul C

My life without an Inogen POC would not be a quality life. It's hard enough to travel with other disability items, but the Inogen One G5 makes my life so much better.
