Regular care and maintenance of your portable oxygen equipment will not only extend the life of your oxygen supplies, but it will ensure 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.
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:
Refer to your operator’s manual for detailed battery care instructions. 
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. Additionally:
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:
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:
Keeping your oxygen equipment clean and well-maintained will allow you to receive 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.
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.
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. If you feel, at any point, like your nasal cannula cannot be cleaned adequately, it should be replaced right away.
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.
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.
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.
