Inogen One G3 Replacement Columns Product Overview Back to top
The Inogen One G3 Column Set is replacement sieve beds for the Inogen G3 mobile concentrator. The G3 Columns are easy to replace and the process can be completed in minutes. The G3 Columns should be replaced every 12 to 18 months to maximize the life of the G3 unit.
A low oxygen purity alert on the LDC screen will display “O2 Service Soon” when the columns need to be changed. To remove the columns, simply press the latch release button located on the bottom of the unit then slide the columns (metal tubes) out of the unit. No special tools are required!
Well, after all, they are required for the G3 to work. I get between 7 tp 9 months of use from them.
The columns are required for the G3 to work. I love the G3. It has given me freedom. I use them on a 2 liter setting. I can go out all day for meetings, hang with friends, doctors' visits, dinner with my wife, yard work or other outdoor work, etc. Basically, I can lead a normal life. I do use the 16 cell battery and occasionally carry a spare battery. With my level of activity, I am able to get anywhere between 7 and 9 months on the sieve cylinders. They would receive a "5" vote from me if they were more truthful in their description of lifr. Maybe they can get 12 months of life is used on a 1 liter setting, but that is probably not a normal usage. If they want to use 12 months as a life cycle, then they should describe the liter setting.

Love the concentrator over all , but the tubes are a disappointment .
The instructions state the tubes life is 1 year, however l am on my third set in less than 2 yrs. costing $149.00 a set is heavy for a person on a fixed income .
