POC Maintenance: Keeping Your POC In Top Condition | Inogen

Keeping Your Portable Concentrator in Top Condition

The Inogen One G3 portable concentrator is known for being more lightweight, quieter, and more reliable than competitive portable concentrators on the market today. You may not know, however, that it has a unique feature making it ideal for the active person: replaceable sieve bed columns.

How an Oxygen Concentrator “Makes” Oxygen

The air we breathe is comprised of 78% nitrogen, 21% oxygen, and 1% other gases in small amounts. An Inogen concentrator removes the nitrogen from the surrounding air by passing it through a section of the unit called a sieve bed. The result is approximately 90% pure oxygen.  This medical grade oxygen is supplied to the oxygen user through a nasal cannula.

Expected Sieve Bed Performance

Over time, the sieve bed loses some of its ability to remove nitrogen from the air. For some concentrators, this can occur as quickly as a few months after you start using it. The Inogen One G3 has a long expected sieve bed life of 18 months to 2 years, depending on how it is used and the environmental conditions in which you live.

The sieve beds are contained in two metal columns that fit into the bottom of the Inogen One G3. When the sieve beds become saturated, a message will appear on your unit to indicate that they need to be replaced. Replacement columns ordered from Inogen will arrive at your doorstep in a couple of days.  Until then, you can continue to use the concentrator.

The columns are sealed, making them clean and easy to replace. A simple tool is included to assist those who may have stiffness or limited movement of the hands.  Used columns can be safely deposited in the trash with no harmful effects on the environment.

Don’t Let Downtime Get You Down!

If you don’t have an Inogen One G3, the only way to renew the sieve beds is to return your concentrator to the provider for servicing. While you may receive a replacement concentrator on loan until yours is returned to you, most often you will simply be without a portable option for a period of time.

It is a fact that all portable oxygen concentrators have sieve beds that become saturated over time, reducing the amount of medical grade oxygen you receive in each breath. Interestingly, the more you use your portable concentrator the longer the sieve beds will last. If you don’t use your portable concentrator regularly, it is a good idea to turn it on and allow it to run for an hour or two each day.

But if you aren’t using your portable concentrator regularly … why not?

Replaceable sieve beds are just another example of Inogen’s commitment to inventing oxygen delivery products that fit your lifestyle. Inogen is innovative oxygen.

    would you have the same information available for the inogen one G2?

    How do you know when the sieve beds need changing. I am in and out of the stable daily — some dust is bound to accumulate. I clean the filters daily or as needed. I go through two batteries in approximately 3 hours on 4 liters.

      Your Inogen One system will give you a message on the display. This is a very help article – https://www.inogen.com/blog/keeping-your-poc-in-top-condition/.

    Are all of the Inogenen models covered by Medicare and Medicaid? What would be the "average" out of pocket expense ? What is the weight of each of the batteries? Can
    the POC's be "plugged into " an average electrical outlet to preserve battery usage? What is the differences of the POC's InogenOne;One G2 and One G3? Does each model come with a "stand alone" home concentrator? What are its dimensions and weight? What is the "recharge" time for
    a battery?

      Hi Russell, I suggest you call and speak with an Oxygen Specialist. A specialist can help answer all of your questions.

    I have a G3 and about every three weeks or so I get a message on the display that the sieve beds need changing and there's also an alarm and red light. I turn off the concentrator and when I turn it on again, the message warning is gone and I no longer get the warning message until about 3 weeks have gone by. This has happened three times over the last couple of months. I'm hesitant to replace the sieve beds if they don't need it. The O2 level seems just fine. I only use my unit about 1-2 hours a day; 30-45 minutes at a time. What should I do?

    1. Inogen Inogen says:

      Hi Patrice, How long have you had your Inogen One G3? Sieve beds (the metal columns) typically need to be replaced every year or so. Please call our Customer Service department at 1-877-466-4364 so that they can assist you. In the meantime, please consult our Inogen One G3 User Manual: https://www.inogen.com/pdf/96-06946-00-01-A-User-Manual-Inogen-One-G3-English-Only-YellowLED-web.pdf

      how did you know the level of oxygen was fine?

  5. Margaret Loftus says:

    I have an Inogen G3. I don’t use it everyday. Should I remove the battery in between uses. It seems to lose a lot of charge sitting for a couple days. Also what battery percent should I charge battery?

    1. Inogen Inogen says:

      Hi Margaret, Most oxygen therapy patients are prescribed oxygen 24/7, so if that is your doctor's recommendations, please use your Inogen One G3 as prescribed. Otherwise, do you have more than one battery for your Inogen One G3? We recommend changing out your batteries so that both batteries get use. Sitting batteries (especially after a prolonged period of time) lose their charge.

      In regards to your second question, depending on what your next activity is you should or shouldn't charge your battery. For example, if you are at 50 or 60% charge, but are planning on going to a 2 hour movie, you should charge your battery (and/or bring a second fully charged battery with you) before you go to the movie theater.
