The removable metal columns provide a quick and easy way to service your Inogen One G5 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 G5 will let you know when it is time for replacement.
Clear step-by-step instructions enable you to easily switch out the column pair without tools – without having to send the Inogen One G5 in for repair like you would with other portable concentrators!
