Inogen One® G4 Column Pair (Sieve Beds)

The removable 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 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.

RECOMMENDED TO REPLACE EVERY 12-18 MONTHS
