FAQ

How many liters of oxygen does the Inogen G4 produce?
The Inogen One G4 delivers 210 ml/min at flow setting 1, 420 ml/min at flow setting 2, and 630 ml/min at flow setting 3, providing 87% to 96% pure oxygen at all settings.

How do I charge the Inogen G4 battery?
To charge your G4 battery, plug the concentrator into a wall outlet using the dual-voltage G4 AC power supply or a car charging port using the G4 DC power adapter. You also have the option to charge the batteries separately with the Inogen G4 External Battery Charger (sold separately).

How do I connect the Inogen G4 to the Inogen Connect app? 
Please follow the instructions in the Inogen Connect: Getting Started Guide. The provider code you’ll need to connect the machine to the app is 30-F80-11-222.

Can I leave the Inogen G4 plugged in all the time?

Can I use the Inogen G4 at night?
Yes, the Inogen One G4 is designed for 24/7 use and can be used while sleeping. Its Intelligent Dose Delivery Technology increases the amount of oxygen in each pulse as breathing rate slows.

Can I use the Inogen G4 with a CPAP or BiPAP?
The Inogen G4 is not designed to be used with CPAPs, BiPAPs, nebulizers, or humidifiers. Using these devices with the G4 can interfere with the proper functioning of your Inogen concentrator.

Is the Inogen One G4 approved for air travel?
Yes. The Inogen One G4 is FAA-approved for commercial air travel. Inogen recommends bringing enough batteries to last 150% of your flight duration, as well as ground time and unexpected delays. Make sure to wrap extra batteries individually and store them in your carry-on baggage.

Check with your airline to find out their specific requirements at least 48 hours before your flight. If they offer onboard electrical power, remove the battery from the concentrator first and plug it into the aircraft in-seat power port using the G4 DC power adapter.

What is the warranty period for the Inogen One G4 Concentrator?
The Inogen One G4 comes with a 3-year standard warranty. The sieve beds, batteries, and other accessories are covered by a 1-year limited warranty.
