Maintenance filters for the Inogen One G3
The Inogen One G3 High-Flow Pre-filter is an essential maintenance component for the Inogen One G3 portable oxygen concentrator.

The concentrator is fitted with two coarse filters. These filters help to protect the device from dust, dirt and other larger particles in the ambient air.

Protection against dust and dirt
During use, the oxygen concentrator draws in air from the surrounding environment. The coarse filters ensure that larger dust and dirt particles are trapped before they enter the device.

In this way, the filters help to prevent contamination caused by accumulated dust and support the concentrator’s proper functioning.
