How do you change a filter for an oxygen concentrator?

If your oxygen concentrator's gross particle filter (intake filter) can be taken out and cleaned, you should do so about once a week. Make sure the concentrator is off and unplugged, and follow the instruction manual for how to remove the filter on your particular model. Wash it with clean water and mild detergent, rinse it well, and allow it to dry completely before putting it back in.

If you have additional questions, please refer to your owners manual for your specific unit's maintenance. If you do not have your owners manual it may be found here: http://www.oxygenconcentratorstore.com/oxygen-concentrator-manuals/
