⭐ Inogen One G3 Replacement Column Pair (RP-321)
Replacement columns for oxygen purity and long-term Inogen G3 performance
The Inogen One G3 Replacement Column Pair (RP-321) is designed to help restore and maintain proper oxygen concentration in the Inogen One G3 Portable Oxygen Concentrator.
Why Replace the Columns?
The columns inside the Inogen One G3 contain sieve material that helps separate nitrogen from room air so the concentrator can produce concentrated oxygen.
Over time, columns naturally wear down and may need replacement.

|---|---|
| Low oxygen purity alert | Columns may no longer separate oxygen efficiently |
| Service alert | Device may require column replacement |
| Reduced performance | Worn columns can affect oxygen concentration |
| High usage hours | Normal wear over time |
| Preventive service | Helps restore proper system performance |
