Everything about the G5/Rove 6 Column Pair
What sieve columns do
Inside every concentrator, zeolite sieve beds strip nitrogen from room air to produce concentrated oxygen. The material slowly saturates with use — typically over 18–24 months — after which purity drops and the columns must be replaced. A column pair must always be installed for the unit to operate.
When and how to replace
Your G5 or Rove 6 tells you when it’s time: a low-priority "O2 Service Soon" alert means replace within 30 days. The swap is a simple latch-out, latch-in procedure — no tools, no service center — fully illustrated in the Column Change Procedure section of your user manual.
Order fresh, install fresh
Sieve material begins its clock once manufactured, so Inogen recommends purchasing columns for immediate use rather than shelf storage. We stock RP-502 pairs continuously — order when your unit alerts you and install on arrival.

Frequently asked questions
How do I know when to replace my columns?
Your concentrator monitors purity and shows an "O2 Service Soon" alert when columns have ~30 days of life left. No alert means no replacement needed.
Can I replace just one column?
No — always replace both columns as a matched pair to keep the pressure-swing cycle balanced.
