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.

You can replace this filter yourself, by following the directions in the owners manual.
The sieve bed must be serviced by a professional. The sieve bed is inside the machine and it filters the nitrogen from the air so that you are only breathing in the oxygen filtered by the machine.

This won't be too often, around an average of every 2 years.

On external batteries, you will likely have a light or alarm to let you know when it needs replaced. Once the battery has been depleted, it's important to recharge it directly afterward.
Handle With Care
The connections can be the most delicate part of a portable oxygen concentrator. Take care when plugging in the cannula tubing or unplugging, and when you plug or unplug it from the AC adapter. You also need to avoid water and too much moisture, since this is an electronic and electronics don't do well around water.
Cleaning Your Portable Oxygen Concentrator
Use a damp cloth to wipe away any dirt or grime from the outside of the concentrator. Use a lint free cloth to wipe away any accumulated dirt from around the filter vent, and from around the connections.
