While getting a newer portable oxygen concentrator is always a good idea, purchasing an older model might be the more economical choice, especially if it is a used or refurbished model. The life of a portable oxygen concentrator depends all on how much it was used over a period of time. Some of the newer models will most likely last much longer than an older one, even if used for the same amount of time, simply because newer models feature better technology.
Most portable oxygen concentrators, however, will last for around 4 to 7 years or more, depending on how often it was used and how well it was maintained. Maintenance for the average portable oxygen concentrator is very minimal, and usually only consists of cleaning a filter.
The component of a portable oxygen concentrator that usually runs down before anything else is the battery, whether its the internal or external battery. Around 300 recharges is when a battery will no longer charge all the way to 100%. Many POC batteries will only recharge from 0% to 80% after 300 recharges.
Even a spare battery that you never use should be charged up to 100% twice a month to give it a longer life span. A battery that is never used a left sitting for extended periods of time will slowly drain, and being idle will actually cause them to deteriorate quicker.
Maintenance to Make Your POC Last Longer
Changing the gross particle filter every 2 weeks is one of the most important ways to take care of your portable oxygen concentrator to make it last longer. Not only will it ensure that you are only breathing in clean and pure oxygen, but it will prevent any particles from going into the inner workings of the concentrator.
Not only that, but if it's not bringing in enough air because of a dirty filter, it will cause the concentrator to work harder, thus shortening its life. You should always follow the directions in the owners manual for how and how often to clean the gross particle filter.
You should also clean off the outside of the concentrator, especially around the vents and around the ports for the rubber tubing, and anywhere else where there is a small opening. Use a very lightly damp lint free cloth to clean off the outside of the concentrator to keep the openings free of dust and debris, as well as make it look nicer.
Keep your portable oxygen concentrator away from high heat and extreme cold, since temperatures like this are hard on any type of electronic. You also need to make sure they don't get wet or too damp from condensation.
