User Question: When Should Inogen One G3 Columns Be Replaced?

The Inogen One G3 is one of the top-rated 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 vital piece of medical equipment needs to be continually 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 Inogen One G3 columns, which are the sieve beds of the unit. 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.

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 the maintenance department when it is time to replace them columns. to replace the columns you will need the owners manual, G3 columns tool and the 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, but the columns can last up to another year.

      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?

    Reply
    • Danielle Jason

      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?"

    I purchased my Inogen G3 before I went to Italy in 2015. I used it maybe a maximum of 20 hours in Italy. I then have not used it until Dec 2017. I would venture to say there is not a total of 40 hours on this unit and I get notice to replace the columns? I am curious why these columns would fail so soon. The unit has not been used. Is there a problem with the unit that would cause this premature need for maintenance? I am still within warranty so if I need to send the unit back for replacement I will.

      Thank you for your comment, Helen. This is a common issue you will encounter if you are not running your concentrator regularly. Think of a concentrator like a car, it's not good for a car to sit unused in a garage, the same goes for your concentrator. Feel free to give our service department a call at 877-303-9289, they'll be able to elaborate on the proper care techniques as well as assist you in remedying the issue.

      Thank you for your comment, EduardoU., Here at the Oxygen Concentrator Store we can ship anywhere within the United States. Do you have someone that can ship you the columns from the United States?

      Thank you for your question, Dolores. If you are seeing a "service soon" message, that is your concentrators way of saying you need to change the columns. Feel free to give our Service Department a Call at 877-774-9271 if you have any further questions!

    I have an inogen one G3. I must change the Column Pair (Sieve Bed) but in Venezuela there is no representation of the manufacturer. Is it possible to replace the zeolite contained in the columns? In Venezuela it is possible to get zeolite. Is it some special type of zeolite? Thanks.

      Unfortunately, we cannot ship outside the United States, however, if you have an address for someone in the USA we can ship them to we can sell/send replacements to them to send to you. For the G3 to work you would need to use columns filled by Inogen.

    I have an Oxygo POC (1-4) through Lincare. From appearance it appears to be identical to the InogenOne G3. Even the supplied manual is a xerox of InogenOne G3 to the point where some of the references were not changed to Oxygo. I am not yet ready for sieve column replacement, but it is approaching time to be concerned about replacement. Are the columns you list for InogenOne compatible with Oxygo?

      You are correct. The OxyGo and Inogen One G3 are the same units. You can order the Inogen G3 sieve columns and they will work with your OxyGo. If you have any further questions please feel free to give our specialists a call at 888-360-9628 or if you prefer email [email protected]

      How long your columns varies on a number of factors like climate and usage. Your Inogen One G3 will notify when it is time to replace your columns and will give you 30 days to do so. If you still have concerns you can contact our customer care center at 877-303-9289.

    I live offshore and I´m travelling to the us in a few days. My Inogen G3 did not pop the replace columns message. Do columns have an expiration date? Can I buy more than one set and store them for when that message appears?

      You will get a message on the machine when it is time to replace the columns. You can purchase extra columns as they do not have an expiration date, however, the warranty is only good for 30 days from the date of purchase.

    I have a Inogen one saying the Columns require changing, as l changed them less than 10 months ago. I thought the life was 12 to 18 months, Reading the comments above, no matter where you are or the usage of the machine, it's another £200 + again

      Chris, The frequency in which the columns need to be changed depends on a number of factors such as climate and usage. People in a more humid climate like Flordia have to change their columns sometime as frequently as every 6 months where those who are in a drier climate like Arizona can go sometime years without having to change them.

    My elderly mother has had her G3 for approx 7 months, I know that she will need a column change sooner or later but am concerned she will miss / ignore the message alert "O2 Service Soon" will the machine repeat the alarm until the columns are changed or will it disappear?

    Reply
    • Margaret Goodman
      Margaret Goodman December 11, 2018 at 2:15 am

      Yes, the alarm will show more than once. There is a 30 days window from the first message alert until they need to be replaced. During those 30 days, you will see the message frequently.
