The Replacement Columns for the Inogen One G4 are removable for quick and easy service. They are sold and used as a pair. Each of the columns contains the sieve beds. The sieve beds are responsible for turning normal, ambient air into medical-grade oxygen. Depending on how often you use your concentrator and your climate your Replacement Columns need to be replaced every 18 months to 2 years.
