I love this quiet little machine
I love this quiet little machine. It takes up so little room, is easy to travel with and does the job of supplying me with oxygen at night while I sleep.

This had changed my life completely. I have back problems and carrying tanks took a toll on my back. Now I have more freedom to enjoy outings with family and friends. Love my Inogen G4.

Inogen has helped me live a fuller life, Before Inogen I did not go out much because the tanks were too heavy to carry and shop. I absolutely love my Inogen. The people working there have been wonderful and kind

Unit is so much easier to utilize compared to the tanks. My only concern is the nasal irritation that occurs with the constant air flow.

I love both of my Inogen O2 machines
I love both of my Inogen O2 machines. The bedside one is a wonderful apparatus......I use it with my Bi Pap machine at night, and also when I’m resting or reading in bed. I love my 10 hour carry bag O2 machine because it lasts a long time and it’s easy to carry in my walker, or attach to the handle of my electric wheel chair. It is wonderful not to have to drag around the cumbersome O2 tanks. It costs $ 11.00 per day for one small tank here. My machines will pay for themselves in a couple of years. I feel so fortunate to have these marvellous machines! Andy was so helpful to us; he explained everything to us ( my husband and I ). Thank you so very much, Inogen !!

I am very pleased with my Inogen Oxygen. It's very light weight and easy to manage. There is no comparison to the one I was issued! It making moving around not nearly as burdensome as the issue I was given by Medicare.

Confidence to leave home
We purchased an Inogen for my 94 year-old father who has severe COPD. There is nothing more heart-warming than to see the confidence the Inogen has given him to be able to leave his home and not worry about breathing! Your company has done an outstanding job of answering all our questions and making sure that we were taken care of. Best purchase ever!

It has been great being free from the tanks. I'm able to do more and not be a prisoner in my own home. I purchased an extra battery and one of them had to be replaced. In oven replaced it free of charge! It has since become defective again and it is being replaced in the same manner.
