Inogen Concentrator Columns
Replacement columns for Inogen oxygen concentrators include the G3, G4, G5, and the Inogen at Home 5L.
Changing your replacement columns when necessary, ensures your unit delivers the highest quality medical-grade oxygen. Replacement columns contain the sieve beds, which take room air and filter out other gases to provide a high oxygen concentration. You should change your replacement columns every 1-2 years. Most replacement columns are easily accessible and easy to change without using tools.
