The output filter prevents micro-particles from being inhaled by the oxygen user, and must always be in place while using your Inogen device. This filter pack will allow you to have extra filters on hand, as the output filter must be changed annually. Please select your concentrator to ensure we get you the correct output filter pack. The RP-101 filter pack is compatible with the Inogen at Home, Inogen G2, and Inogen G3. The RP-410 filter pack is compatible with the Inogen G4 and Inogen G5.

*Please note: If you have not purchased the Inogen Output Filter Kit, we recommend that you add it to your order now. That kit includes the wrench you need to access your machine’s output filter.
