Despite how dependable and sturdy they are, you have to remember that they are only electronics and need to be maintained from time to time, and protected the way you would protect a cell phone or a camcorder. You also have to make sure you keep it clean and in top working order, because you need it to keep you healthy. Maintaining the right amount of oxygen in your blood is extremely important, because every cell in your body needs oxygen.
Replacing Filters
Many concentrators have gross particle filters that need replaced every 2 years. Read your owners manual that came with your portable oxygen concentrator to see how often it will need changed, so you can purchase a new one and have it on hand when you are supposed to replace it. Some concentrators will have a light or alarm that goes off when it is time to change the filter. The gross particle filter is important because it filters the larger particles that are in the air that you don’t want to breathe in. You can replace this filter yourself, by following the directions in the owners manual.
