Replacement columns for the Inogen Rove 4
The Inogen Rove 4 Columns are replacement columns for the Inogen Rove 4 portable oxygen concentrator. The columns are a key component of the device and ensure that the concentrator can deliver concentrated oxygen.

The columns filter nitrogen out of the ambient air. This leaves oxygen with a higher concentration for the user.

Important for oxygen delivery
An oxygen concentrator draws in ambient air and separates the nitrogen from it. The columns play a central role in this process.

Properly functioning columns are therefore essential for the performance of the Inogen Rove 4 and for reliable oxygen delivery during daily use.
