Care and Maintenance of Oxygen Equipment

INOGEN ONE G3, G3 care, Inogen One G3 maintenanceRegular 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 for oxygen concentrator maintenance on all Inogen One units to keep your oxygen equipment in tip-top condition.

Battery Care for Inogen One Units

Inogen One Portable Oxygen Concentrator units come with a single lithium-ion battery. To sustain the life of your battery and ensure optimal performance of your Inogen One unit, keep the following guidelines in mind for your oxygen concentrator maintenance:

  • Use only an Inogen One Battery with your Inogen One Portable Oxygen Concentrator.
  • Keep your battery dry at all times. If it gets wet, stop using it and bag it in a zip-top bag, then take it to your local battery recycling location or e-waste facility. Never throw a lithium ion battery (or any battery) directly in the trash.[1] 
  • To extend the run-time of your battery, avoid using it in extreme temperatures, including 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 40-50%.
  • Avoid discharging or recharging your batteries completely when possible.
  • 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 Oxygen Concentrator Maintenance

Whichever brand nasal cannula suits your needs, Inogen recommends that you change your nasal cannula on a regular basis according to your health care provider’s recommendation and the manufacturer’s instructions as part of your oxygen concentrator maintenance routine. Generally speaking, most experts recommend changing your nasal cannula every two weeks.[2] Additionally:

  • Clean your nasal cannula daily between replacements to ensure that bacteria does not build up and cause infection. Follow your manufacturer’s instructions for best cleaning practices.
  • To ensure proper breath detection and efficient oxygen delivery with your Inogen One unit, your nasal cannula should be single lumen with tubing no longer than 25 feet.
  • For best results, talk to your doctor, respiratory therapist or oxygen supply company about which kind of nasal cannula suits you best. Look for a secure attachment that does not restrict flow to your Inogen One Portable Oxygen Concentrator.

Concentrator Case

Keeping your Inogen One Portable Oxygen Concentrator clean and dust-free is an essential part of oxygen concentrator maintenance and will help keep your unit in top working order. Here are the basics:

  • Clean the exterior of your Inogen One unit whenever it becomes visibly dusty or dirty. Wipe down the outside case of your Inogen One Portable Oxygen Concentrator with a clean cloth dampened with water and a mild detergent (DawnTM works great). Avoid using harsh chemicals such as isopropyl alcohol or ethylene chloride for oxygen concentrator maintenance, and never use petroleum-based products to clean your oxygen equipment.
  • To reduce the risk of electrical shock and damage, never submerge your Inogen One Portable Oxygen Concentrator unit or any of its accessories in water or allow it to come into contact with water. While Inogen One units have been tested to withstand rain while walking from a car to your home, it is recommended that you use an extra layer of protection, like the provided carry bag, to protect your unit from getting wet.[3] 

Particle Filters Oxygen Concentrator Maintenance

Your Inogen One Portable Oxygen Concentrator comes equipped with two particle filters. Both must be cleaned weekly to ensure ease of air flow. To complete this essential oxygen concentrator maintenance, remove the filters from the front of the device, then:

  • Clean your particle filters using water and a mild dishwashing detergent such as DawnTM
  • 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 our Inogen Portable Oxygen Concentrator units and all their parts, refer to the Inogen One User Manual or feel free to contact us and we can walk you through the process.

Frequently Asked Questions About Oxygen Concentrator Maintenance

Can I use Lysol or other antiviral cleansers on my Inogen One Portable Oxygen Concentrator?

Please only use a cloth dampened with water and a mild detergent, like DawnTM, to clean your Inogen One unit, following the procedures outlined in the Instructions for Use in your manual. If you must fully decontaminate your unit, the CDC recommends using an antiviral disinfectant wipe on the surface of your Inogen One Portable Oxygen Concentrator. Inogen has determined that using wipes will not hurt the function of the unit.[4]  

Can I use Lysol or other antiviral cleansers on my nasal cannula?

These types of cleansers are not safe to use on your nasal cannula. You can clean your nasal cannula with a sanitizing solution, as directed by the manufacturer, or you can wash your nasal cannula in warm water with mild detergent, and follow with a vinegar rinse. It is also recommended that you have at least two nasal cannulas on hand in case you need to wash one of them.[2] If you feel, at any point, like your nasal cannula cannot be cleaned adequately, it should be replaced right away. 

What do I do when it’s time to clean my particle filter?

In order for particle filters to be cleaned properly, they will need to be hand washed with mild detergent and air dried. If you need to use your Inogen One Portable Oxygen Concentrator 24/7, or for a significant portion of the day, we suggest purchasing extra filters so that you can wash and dry your particle filters properly without experiencing interruption of your oxygen therapy. 

When should I replace my particle filters?

If your particle filter becomes misshapen or damaged, you should replace it. Order 2-packs of new particle filters for your Inogen One Portable Oxygen Concentrator any time under Parts & Accessories on our website. 

When should I replace my Inogen One batteries?

Unfortunately, all batteries slowly lose their ability to hold a charge over time. However, with proper use and care of your Inogen One lithium-ion batteries, you can extend the life of your battery as much as possible. Follow our Battery Life Tips to help you batteries work more effectively. However, if you notice they simply do not charge properly or hold the charge you need anymore, you should replace them. 

How do I know when to replace the columns inside my Inogen One unit?

Your Inogen One unit will give you a low priority alarm to indicate that column maintenance is required within 30 days. You can then order new columns, if you do not already have them, and follow our instructions (found inside each unit’s manual) to replace the column assembly on your own. If you need additional assistance, contact Customer Care at 1-877-466-4364. 

What do I do if my Inogen One unit needs to be serviced?

If you receive an alarm or error code you do not recognize, you need help with installation of a part or if you feel your Inogen One needs any service, please call our Custom Care line at 1-877-466-4364. We are always happy to help you with any oxygen concentrator maintenance and to troubleshoot any issues, and we can walk you through the processes step by step. We’re here to ensure your Inogen One Portable Oxygen Concentrator works exactly as it should.

What should I do with old batteries, columns and other Inogen parts and accessories?

Please contact your local recycling center to discuss how to recycle or dispose of these parts and accessories. You can also contact your local e-waste facility for directions on safe disposal. Please do not discard these items in your regular trash, but store them in plastic zip top bags until they can be properly recycled or disposed of safely.

    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 – https://www.inogen.com/product/inogen-one-g3-columns/. 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.

  11. Avatar 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. Avatar Bobby Ross says:

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

  13. Avatar 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.

    1. Web Admin Web Admin says:

      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 – https://www.inogen.com/product/g3-replacement-particle-filters/

  21. Avatar 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: https://www.inogen.com/product/ac-power-supply/

    Regarding Judy's question posted July, 2017: My husband purchased an Inogen One G3 5/2014. We do not see a place for the output filter. Do we have to remove the cannula metal connector? He does not recover as quickly as he used to on the Inogen. No error codes are noted.

    1. Inogen Inogen says:

      Hi Beverly, Please call our Customer Care department at 1-877-466-4364.

  24. Avatar Marsha says:

    I am a NICU nurse for a small level 2 nursery. I was curious if your product has the ability to deliver lower Oxygen % at infant flow rates. It is cumbersome to have to frequently change both O2 and compressed air tanks on a transport bed. These beds have battery backup so if your device could give a flow from 5-10 lpm at varying percentages of O2 it would be a better tool. We give cpap from 5-10 lpm but use 21% to 40% usually.

    1. Inogen Inogen says:

      Hi Marsha, Thank you for your questions. I will pass your email address to our B2B Sale Representative and he will follow up with you.

  25. Avatar Kean says:

    I always hear a little beeping when I have my machine on and using it. What does that noise mean?

    1. Inogen Inogen says:

      Hi Ronna, The beeping or puffing noise is the sound of your POC mechanically converting normal air to medical-grade oxygen.

  28. Avatar Eve says:

    Hi, my warrantee is over, I purchased the inogen second hand but it was not used regularly. I used it also only on exertion.
    My machine showed service soon , I called inogen and they said I needed to order new columns but my unit stopped charging completely.
    I was charging it and instead of charging it, it emptied it completely and now there is no response when I use the
    charger.
    I am surprised that such an expensive machine needs so much maintenance.
    I live in montreal,Canada , another reason making it difficult to have a maintenance as it costs a fortune to send back
    Please advise is there a place here that does maintenance or advise what I should do now?
    Thank you
    Is there a place within Canada or near

    1. Inogen Inogen says:

      Hi Eve,
      Thank you for contacting us. Unfortunately, we do not have a company in Canada that we can suggest for repair and maintenance. Please call us at 877-466-4364 and we can discuss the potential costs for you to send it to us. Further, we can help you troubleshoot it over the phone. Thank you.

    Is there a lower filter (under the battery, between the two columns) that can be cleaned or replaced?
    Looks like there is some dust build up showing under the clear plastic cover. – this is for an Inogen G3 (1-5 setting ) unit.

    1. Inogen Inogen says:

      Hi Dan,
      The lower filter does not need to be changed and the gray color is normal. If you end up receiving a system error, you can call us and we can assist you.

    How do you dispose bad batteries that will no longer charge?

    1. Inogen Inogen says:

      Hi Phil,
      We suggest that you visit a recycling center to dispose of them. They are like cell phone batteries and can be recycled at e-waste recycling centers. Your city or county should have a list of locations online. Thank you!
