Care and Maintenance of Your Oxygen Equipment

Regular care and maintenance of your portable oxygen equipment will not only extend the life of your oxygen supplies, but it will guarantee that you’ll receive optimal air flow with uninterrupted service.  The following guidelines are recommended by Inogen One to keep your oxygen equipment in tip-top condition:

Battery Care –

The Inogen One G3 Concentrator comes with a Lithium Ion Battery. To sustain the life of your battery and ensure optimal performance of your Inogen One G3 concentrator, keep the following guidelines in mind:

  • Use only the Inogen One G3 Battery with Your Inogen One G3 Concentrator.
  • Keep your battery dry at all times. If it gets wet, stop using it and discard it immediately in the appropriate trash receptacle.
  • A single Inogen One G3 battery powers the concentrator for up to 4 hours in most temperatures. However, to extend the run-time of your battery, avoid using it in temperatures less than 41˚F (5˚C) or higher than 95˚F (35˚C).
  • Store your batteries in a cool, dry place while they still have a partial charge of 40 to 50 percent.
  • Label multiple batteries (A, B, C or 1, 2, 3 etc.) and rotate their use accordingly.
  • Don’t allow your battery to remain dormant for more than 90 days at a time.


Nasal Cannula –

The nasal cannula that you use depends upon which oxygen supply company you choose. Whichever brand suits your needs, Inogen One recommends that you change your nasal cannula on a regular basis according to your health care provider’s recommendation and the manufacturer’s instructions. Additionally:

  • To ensure proper breath detection and efficient oxygen delivery, your nasal cannula should be single lumen with tubing not longer than 25 feet.
  • For best results, use only a high flow nasal cannula like the Salter 1600Q. Others may restrict your oxygen delivery and/or not attach securely to the Inogen One G3 Concentrator.


Concentrator Case –

Keeping your Inogen One G3 concentrator clean and dust-free will help keep it in top working order:

  • Wipe down the outside case of your Inogen One G3 Concentrator with a clean cloth dampened with water and a mild detergent (Dawn works great). Avoid using harsh chemicals such as isopropyl alcohol, ethylene chloride or petroleum-based products to clean your oxygen equipment.
  • To reduce the risk of electrical shock and damage, never submerge your Inogen One G3 concentrator or any of its accessories in water or allow it to come into contact with water.


Particle Filters –

Your Inogen One G3 Concentrator comes equipped with two particle filters. Both must be cleaned weekly to ensure ease of air flow.  After removing the filters from the front of the device:

  • Clean your particle filters using water and a mild dishwashing detergent such as Dawn. Rinse well and let air dry before re-using them. If you live in a dusty environment, it’s recommended that you clean your particle filters more often.

Keeping your oxygen equipment clean and well-maintained will allow you to receive superior, portable oxygen delivery for many years to come. For more information about care and maintenance of the Inogen One G3 Concentrator and all its parts, refer to the Inogen One User Manual.

    My mother's G3 is alarming for low oxygen after approximately 1 hour of use. We live in RI. Does the unit need to be shipped to the manufacturer to be serviced?
    Thank you

    1. Web Admin Web Admin says:

      It sounds like you need to replace the columns on the machine. You can but them online – Have you replaced them before? Inogen recommends replacing the columns every 18 months to two years. In certain operating conditions, earlier replacement may be required. The Inogen One G3 will let you know when it is time for replacement.

    My husband no longer needs to use oxygen, so we would like to store our machine and the two batteries . Can you tell me how I should store the machine and batteries for a long term period. thank you.
    Mrs Morris D. Dannelly

    1. Web Admin Web Admin says:

      The machine should store for a while. This issue is the batteries, they work just like a laptops batteries. If you don't use them they will not hold a charge over time.

  11. Bobby Ross says:

    Is there a filter under the battery on the G3 that has a plastic cover with 4 star shaped head screw? What size wrench fits those screws and are we to clean that filter as well?

    1. Web Admin Web Admin says:

      They are called Torx screws. The filter you see is part of the internal system. You do not need to change it. You do need to change the filters on the side of the machine from time to time. Have you replaced them before? You can order them on from the web site.

  12. Bobby Ross says:

    Thanks. and yes I recently changed those 2 particle filters.

  13. carolyn klein says:

    I have a concentrator which I use at home. Does it need any filters? cleaned or maintained with preventative care? 1020001 ref ever/flo is only number I could find. This machine has worked with no problem for a year plus, but my husband thought perhaps some maintenance was needed. Thank you.

      Replacement eco-friendly particle filters keep dust, pet hair, and other air-borne contaminants away from your oxygen.

      The removable particle filters cover the air intake screens to filter out dust, pet hair, and other air-borne contaminants. They are washable and reusable, making them one of the eco-friendly features of Inogen concentrators. Users should wash and dry the filters weekly (more often in very dusty environments) to help keep the concentrator working properly.

      Inogen recommends replacing the filter when it become misshapen or when the screen is damaged. Replacement filters for the G2 and G3 portable concentrators are sold in packs of two; the replacement for the At Home filter is a single, larger filter. Take a look at the filters –

    How do I get new cannula tubing?

  21. Robert Caraher says:

    The AC cord for my G2 only works if it’s stretched extremely taut, thus making the connection in order to charge it. Once I’ve stretched it tight and made the connection, I use duct tape to hold the cord in place. Is there any way this can be repaired?

    1. Inogen Inogen says:

      Hi Robert, It sounds like your AC cord needs to be replaced. To purchase a replacement, please visit:
