Product description

The Inogen One G4 is designed for oxygen users looking for a small, quiet and lightweight portable oxygen concentrator. Weighing only 3.3 pounds*, the Inogen One G4’s portable size and battery pack can empower you to do activities outside the home such as running errands, visiting family or taking a vacation. The Inogen One G4 meets FAA requirements for travel.

The Inogen One G4 can be plugged into a power source at home, on the road or it can be used with an external battery when away from home. It gives you more options, simplified.

When it comes to warranties**, Inogen understands peace of mind is important. We’ve put together two customer warranties to best suit your individual needs. Our first is a standard Three-Year Warranty, while the second option is a Lifetime Warranty ensuring your concentrator is covered for life.  No matter which warranty you choose, you can always depend on Inogen.

Inogen Systems require a qualifying RX prior to shipment. Once you place an order an Oxygen Specialist will follow up with you to help you gather your RX information.
