About the Inogen G4

What have you given up since you started oxygen therapy? Where would you like to go, what would you like to do? With an Inogen One portable oxygen concentrator, almost anything is possible.

The concentrator is made to make your life easier. There are no regulators to switch or portable tanks to refill or replace, just a couple of buttons. That’s it.The new Inogen One G4 delivers the independence of Inogen’s G3 oxygen concentrators, but it’s smaller, and lighter for lower oxygen needs.

Once you try it, you’ll wonder why anyone would use something else.If you haven’t seen an oxygen concentrator from Inogen, then you haven’t seen anything like it. Embrace the simplicity of Inogen’s portable concentrators and eliminate the worry of running out of oxygen.
