What is the Average Lifespan of a Portable Oxygen Concentrator?

Portable oxygen concentrators were designed to provide the oxygen therapy you need while you are staying active or traveling. They were also meant to last and are built to be tough. They are made to be safe, even while in use on an airplane, as well as small and lightweight enough to comfortably take anywhere. The one thing they cannot do is get wet, just like with any other electronic machine. Other than that, they can go anywhere that you can comfortably go.

But just how long will they continue to provide the oxygen you need? This depends on the necessary maintenance, and how often it gets checked out and maintenance, as well as the brand and the model. There is no solid number to tell us how long a portable oxygen concentrator can last. What we can do, however, is give a rough estimate based on a few different factors.

How Long Do Portable Oxygen Concentrators Last on Average?

A portable oxygen concentrator should no longer be used after the oxygen purity goes below 80% on the dosage setting that you use. Below this percentage, it won't be able to give you the oxygen therapy that you need to treat your illness. This happens after between 800 to 1,500 hours of use. As mentioned before, the exact number depends on the model, how well you take care of it, and how often you use it.

When is a Portable Concentrator Considered "Used"?

A portable concentrator is no longer considered new after it has been used for over 300 hours. It will still work just as well for many more hours, but it would have to be sold as “used and refurbished” and many health insurance companies will not cover a used model.

How Long Does a Portable Oxygen Concentrator Battery Last?

After being recharged 80 times, the battery will no longer be able to charge all the way to 100%. You will start to notice that it will only charge up to 80%. This is when you will need to get a new battery. The battery will still charge the unit, you will just need to recharge it sooner.

How Often Will My Portable Oxygen Concentrator Need Serviced?

You should read your users manual for your particular model. Some portable oxygen concentrators have a gross particle filter that will need to be replaced once every 2 years. It may even have instructions on taking it out and cleaning it. This filter is important because it catches the dirt particles and other foreign matter from being taken into the inner workings of the concentrator.

There is also another filter inside that you won't be able to replace yourself, but a service technician should be called to do. You should never try to change more than the gross particle filter yourself.

    I am 80 years old and in moderately good shape but have COPD. I don't need oxygen in Chicago area, but think I would need it over 5,000 ft. I want to travel to the National Parks this fall, would the Oxygen concentrator be the answer and how would I use it, how much does it cost etc?

      The cost of an oxygen machine to rent for a week starts at $245.
      These machines are rated up to 10,000 feet so not an issue operating this
      machine at this elevation point. The liter flow and setting is a key factor as
      to how much oxygen you would need that way we can recommend the best machine for you make and model wise. Please review and let me know your thoughts.

        That feels like a yes or no question there, not a call our department question.

          Unfortunately, that is not the case. Each brand and unit is different. Not only that, how you use, store, and maintain a concentrator will affect it's lifespan. You will also need to take into account your location, climate, and altitude. We suggest contacting our support department to work through these in-depth and personal questions with a dedicated representative.

    You said above, “... concentrator should no longer be used after the oxygen purity goes below 80% on the dosage setting that you use.
    How do I as a user detect the purity level?
    I have an Inogen One G2(old model), a G4, and an Airsep Focus. Don’t use constantly, but try to give each unit some run time each week...just to keep em functional.

      Thank you for your comment, Dave. If your concentrator drips below 80% purity your machine will alert you. Depending on the brand and unit, this will be an alarm or a message appearing on your screen indicating something to the effect of "low oxygen" or "low purity."

    Will the oxygen level go back up once it has been serviced? Or is it that once it drops down to below 80% it can not go back to it's previous levels even after servicing.

      Thank you for your comment, Hollyanne. When sending your unit in for service, especially for a specific issue such as low oxygen purity, the manufacturer would do their best to remedy the situation. Depending on your remaining warranty, if they are unable to fix this issue and the issue was not user initiated, they would potentially replace your unit. Feel free to give our Service Department a call at 877-303-9289 if you'd like to know more.

      This is a reply to Sarita though my reply may be helpful to others. I myself live out in the country where power is not always reliable. To compensate I have two large deep cycle batteries that I have hooked up to a Pulsetech charger/maintainer (this brand prevents sulfer battery buildup over the years) when power is out a "pure sine wave" power inverter (pure sine wave is important as a modified sine wave inverter will damage a oxygen concentrator) keeps me going running an extension cord to the concentrator from the inverter (an inverter takes the 12 volts from the deep cycle battery and turns it into 110 AC that the oxygen concentrator can use). These batteries will keep the concentrator going a little over four days with my setup. I also bought some cheap harbor freight solar panels in case power went out longer. However to date have never had to use them as power came back and recharged from wall. Batteries + Pulsetech charger + pure sine wave inverter ran me about $600 off eBay. But worth the peace of mind!

      You would need to contact the company where you originally purchased the machine from. they can help you determine if the machine is under warranty still if it needs to be sent in and any cost associated with it. Unfortunately, without the serial number and additional information, I am unable to answer this question. If you did purchase the machine from us please give us a call at 877-774-9271 and we can better assist you.

    My friend wants to give me an oxygen tank "Lif-O-Gen model 500 that has never been used and has a date on the bottom of the tank dated November 19, 1975. I'm thinking a 51 year old tank isn't safe? Can you help? Thank you, Janice

      Hi Janice, There have been many advancements in oxygen concentrators since this machine was manufactured. We strongly recommend disposing of this and getting one that is more up-to-date.
