Oxygen Question: How Do You Know When Inogen One G3 Columns Should Be Replaced?

The Inogen One G3 is one of the best portable oxygen concentrators on the market. Like all the others, it still needs maintenance, and will require replacement parts to keep it in good working order.

This important piece of medical equipment needs to be constantly working to the best of its abilities because you rely on it for your health.

One of the major parts that will need to be replaced is the Column pairs, which are the sieve beds of the Inogen One G3. The sieve bed works to filter out nitrogen from the air coming into the concentrator. It's the second filter that the air passes through to be concentrated into oxygen.

The air we breathe contains mainly nitrogen and oxygen. If the sieve beds are functioning properly, it won't be able to remove enough nitrogen, and the oxygen coming through the nasal cannula will be less pure. That means you won't be getting the oxygen dosage that you need to treat your COPD, or other diseases that affect the lungs.

When to Replace the Inogen G3 Columns:

The Inogen One G3 will alert you when you need to replace the columns. The "Low Priority Alert" will read: “O2 Service Soon”. This gives you 30 days to have the columns replaced, before the concentrator starts to fail to function properly.

Luckily, you don't need to call in a maintenance man to replace them for you, and it doesn't require any special tools or training. You will need to refer to the owners manual, and purchase replacement column pairs.

For full instructions on how to change the columns in an Inogen One G3, see the "Column Change Procedure" section of Chapter 6 of the user manual. Replacing the columns is just as easy as replacing batteries.

The ease of maintenance is another reason the Inogen One G3 is such a popular portable oxygen concentrator. With many other models, you would need to send it in to get repaired. The replacement columns are also inexpensive. The 30-day prior alert gives you plenty of time to order them online. You should be able to replace them long before the 30 days is up.

How Long Do New Column Pairs Last?

This can depend on how often you have to use your Inogen One G3. You probably won't have to replace them again for at least another year.

    How do I dispose of the old columns now that I have received new ones and replaced the old with the new?

      Great question, Nancy. Once you replace your Inogen One G3 columns, you can simply and safely dispose of the old columns in the trash. No return or pick-up necessary!

        Is there a recycling process for this item? They will not break down in a landfill in 1000+ years

          Thank you for your comment, Cheryl. If you are interested in recycling your sieve bed columns, you will need to contact the OEM (Original Equipment Manufacturer). Nearly all sieve bed cores or columns are recycled to the OEM or to an authorized 3rd party. The sieve bed columns are actually refilled with fresh material and sealed to the OEM's specifications. The used zeolite within the columns is recycled in various industrial applications.

    Is it normal for the change column message to come on after only two months of use?

      Thank you for your comment, Jan. We can not say one way or the other if that would be considered "normal" as we do not have the full information on your machine or situation. The machine's brand, the year it was purchased, the remaining warranty, climate, altitude, how you store your unit, and how frequently you utilize the machine will all play a part in the "change column" message. If you'd like you can give our service department a call at 877-303-9289, they'll be able to work through all of these questions with you to help troubleshoot your machine.

      Thank you for your comment, Sheila. Often times the cost of renting a machine is much more than purchasing one outright. If you're looking for more affordable options give us a call at 877-774-9271 to discuss the possible solutions available to you. As for the low pitched winning sound, is this accompanied by any messages on the unit's screen? Anything indicating "no breath detected" or even "error?"
