This inlet filter protects your Inogen At Home machine from the dust and debris in the air around you. It is located on the back of your machine toward the top, and it can easily slide upward and off of the concentrator when it is time to replace it.
*Please note: Your machine will let you know when it is time to change this filter by displaying the priority error “Service Needed” indicator. If you have any questions on how to find out which error message indicator your machine is displaying, please contact our service department at 1-800-595-3551.
