Product Description:
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 convertnormal air with lower levels of oxygen concentration to supply a high concentration of oxygen. These sieve beds wear down after prolonged use.
Inogen recommends replacing the columns every 18 months to two years. 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!
I followed the instructions to the T, however, after 3 attempts with not being able to reset the columns, I had to ask for assistance. It appears that there is a special way to push the buttons indicated to get the proper settings. I continuously got the Blue Tooth (which I don't have).
