    How an Oxygen Concentrator Works

  • Maintenance


    The following items need to be cleaned regularly:

    • Particle screen – To ensure adequate air flow through the device, the particle screen should be cleaned according to the manufacturer’s instructions, generally on a weekly basis, using a mild detergent and water. The particle screen must be air dried before reuse.
    • Surface – The surface of an oxygen concentrator should be regularly cleaned according to the manufacturer’s instructions, using a mild detergent and water. Important: The concentrator should never be submerged in water.

    The following items need to be replaced regularly:

    • Nasal Cannula – request new nasal cannulas here
    • Filter – request new filters here
    • Columns – The device will advise a  low priority message on the display screen and alert with a double beep with a solid red or yellow light that column maintenance is required within 30 days. To order new columns, click here and then follow the instructions for replacing the column assembly.

    Frequently Asked Questions

    Q: Can I take the Inogen One onboard commercial aircraft?

    A: Yes. With the Inogen One, traveling with your oxygen is easy. The FAA now allows the Inogen One aboard all commercial aircraft whose flights originate or terminate within the United States. Check with your airline provider for any inflight restrictions before arriving at the airport. Bring enough charged batteries with you to power your Inogen One for no less than 150% of the expected duration of the flight, plus a conservative estimate of unanticipated delays.

    Q: Is it safe to allow my Inogen One through the airport screening machines?

    A: Yes, it is safe to walk through the screening machines while using your Inogen One.

    Q: Is it safe to allow my Inogen One in cold/hot environments?

    A: Yes, it is safe to use the Inogen One in these conditions; if the user can tolerate the environment, then most likely the Inogen One will function without any trouble. However, if the Inogen One becomes too cold/hot, an alert will be displayed on the device.

    Q: Is it safe to allow my Inogen One if I also have a pacemaker?

    A: Yes, there will be no interference between the two devices. 

    Q: Is it safe to allow my Inogen One when I have an x-ray or MRI?

    A: Yes, we recommend attaching a 25ft nasal cannula to the device and setting the Inogen One with the technician.

    Q: Is the Inogen One pulse dose? Can I use it at night?

    A: Yes, the Inogen One is pulse dose, but we have developed new pulse dose technology, Intelligent Delivery Technology. Inogen’s Intelligent Delivery Technology is highly flexible to changing environments and meters oxygen delivery through the system to promote increased oxygen delivery during sleep for most patients. As breathing rate slows, Inogen’s Intelligent Delivery Technology increases each bolus dose. The technology in each Inogen One is effective at providing the necessary oxygen for most ambulatory patients during all phases of daily activity and during sleep. The Inogen One is designed to be used 24 hours a day, 7 days a week.

    Q: How long does the Inogen One battery last?

    A: The external battery is rated to last up to 2.7 hours (at flow setting of 2), however, that time varies on flow setting and breath rate. The Inogen One battery is charged by plugging it into a power source, whether that be an electrical outlet or the cigarette lighter socket in a car.

    Q: Can I smoke around my oxygen concentrator?

    A: Open flames should always be avoided where oxygen is in use. That includes matches, lighters, candles or smoking in any form. Anyone who wishes to smoke should do so out of range of the unit.

    Q: Can I use my Inogen One in the rain?

    A: Yes, the Inogen One was tested to withstand rain while transferring from a car to a home, for example, and the carry bag (backpack and hip bag)  provides another layer of protection. 

    Q: Can I use the Inogen One with my C-PAP/BiPAP machine? 

    A: No, Inogen does not allow the device to be used in conjunction with humidifiers, nebulizers, C-PAP, BiPAP or connected to any other type of devices. Doing so may impair performance or damage the equipment. 

    Q: Can I use my Inogen One with a swivel connector?

    A: No, we cannot recommend the use of the Inogen One connected by a swivel connector as there is possibility of oxygen flow to be restricted. However, all Inogen One POCs are approved for use with a nasal cannula up to 25 ft. in length.

    Q:  I heard something in the news about rechargeable batteries causing fires, and that they were no longer going to be allowed by the airlines.  Does this mean that I can’t use my Inogen One when I fly?

    A:  No – you can rest assured that the Inogen One G3, G4  and G5 are approved by the FAA for transport and use on domestic airlines.  In addition, you can transport extra Inogen One lithium ion batteries as long as these are packed in your carry-on baggage.  Please contact the airline with which you’ll be traveling ahead of time to determine their specific guidelines for transporting and using oxygen on board their aircraft.

    For more information on the FAA’s ruling regarding lithium ion and other types of batteries, you’ll find a comprehensive summary at…

    Q: What are the washing instructions for the carry bags?

    A: Hand wash only in warm water, Do NOT Tumble Dry, Do NOT Iron, Do NOT Bleach, and allow to dry immediately away from direct sunlight and heat.
