The removable metal columns provide a way to self-service your Inogen^® Rove 6^™ or Inogen One G5^®. Sold and used as a pair, the columns contain the sieve beds that convert normal air with lower levels of oxygen concentration to a high concentration of oxygen. These sieve beds wear down after prolonged use.

The “replace columns” alarm will alert you when the (sieve) columns need to be changed, typically once a year. In certain operating conditions, earlier replacement may be required. The Inogen^® Rove 6^™ or Inogen One G5^® 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^® system in for repair.
