Inogen One G5 columns

The two columns (or molecular sieves, or just sieves) are positioned inside the Inogen One G5 portable oxygen concentrator. They filter out nitrogen from the air, leaving purified oxygen for effective oxygen therapy. The active ingredient inside the columns deteriorates slowly, this is a natural process. When the effectiveness of the columns drops below a certain level, the concentrator will warn you, showing the symbol below on the display. You can still use your Inogen One G5 concentrator safely for 30 days after the message first appears.

Lifespan

The Inogen One G5 columns have a newly designed housing, less exposing them to moisture and other external influences. To maximize their lifespan, it is recommended to use the concentrator regularly; this helps keeping the columns dry. When the inside of the columns is exposed to moisture, the active ingredient will stick together, reducing its ability to filter out nitrogen. There is a 1 year warranty on this product.
