Inogen One G4 columns

An important part of an oxygen concentrator are the columns, also called sieve beds. These sieves filter the nitrogen from the ambient air, leaving pure oxygen.

Most oxygen concentrators have internal columns inside the housing, making them hard to replace. With the Inogen One G4 however, you can easily do it yourself.

Because the filtering of the nitrogen is a natural process, the quality of the columns will slowly deteriorate. The lifespan of the columns is measured continuously by the concentrator. When the remaining lifespan reaches a certain level, the message 'Replace columns' will show in the display of the Inogen One G4. As of this moment, you can still use your oxygen concentrator for 30 days. 

Lifespan

The expected life of the columns is 12 to 24 months. For optimal sieve bed (columns) life, the product should be used frequently.

Change sieves

With the columns, a manual is included which explains how to change them. The procedure to change sieves is also available as PDF document.
