What is the expected maintenance on the Inogen G3?
The maintenance on the Inogen G3 is minimal. We recommend cleaning the particle filter weekly. The particle filter can be found on the back of the machine. To clean it, remove the filters and run it under water for a few minutes and then let air dry completely before replacing it. In addition, the columns will need to be replaced; generally, this will be after 1-2 years, but is dependent on the machine’s usage and the climate.
