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.
