G4 REPLACEMENT COLUMN PAIR
$118

The removable metal columns provide a way to service your Inogen One G4 without having to send in the product for repair. Sold and used as a pair, the columns contain the sieve beds that convert normal air with lower levels of oxygen concentration to supply a high concentration of oxygen. These sieve beds wear down after prolonged use.

The life of the (sieve) columns is guided by the “replace columns” alarm and is typically within a year. In certain operating conditions, earlier replacement may be required. The Inogen One G4 will let you know when it is time for a replacement.

Step-by-step instructions enable you to switch out the column pair without tools – without having to send the Inogen One G4 in for repair.

EXTERNAL BATTERY CHARGER
$342

The Inogen One G4 External Battery Charger will charge your Inogen One G4 single and double batteries.

If you are active and need to recharge multiple Inogen One G4 batteries simultaneously, then order an extra charger to help you charge more batteries as needed.

AC POWER SUPPLY (G4)
$94
The AC power supply is specifically designed for use with the Inogen One G4.
INOGEN ONE G4 PARTICLE FILTER
$14

The particle filter is designed to filter out large particles with >90% efficiency so that the air you breathe is as clean as the air around you. Wash the particle filters weekly (more often in very dusty environments) to help keep the concentrator working properly.

Inogen recommends replacing the filter when it becomes misshapen or when the screen is damaged.
