3.2.2. Particle Filter Cleaning and Replacement
On the sides of the Inogen One G5, ambient air passes through two particle filters that
remove dust fragments. These particle filters must be cleaned on a weekly basis to
ensure adequate air flow through the device. If the particle screens are not cleaned
frequently, the life expectancy of the concentrator will be shortened due to higher internal
operating temperatures.
Particle filters should be cleaned using a mild liquid detergent (such as Dawn
water solution; be sure the filters are rinsed in water and allowed to air dry before reuse.
Additional replacement filters may be obtained from Inogen. There are other types of
filters inside the Inogen One G5 that provide additional filtration. Maintenance of these
filters is not required under normal operating conditions.
3.2.3. Column Change Procedure
There are two columns in the concentrator as a single metal assembly that can be seen
on the underside of the device. These columns should be removed and replaced when
column service is required (indicated by "Change Columns" message). Ensure adequate
time is allotted to complete all steps without disruption when performing this
maintenance.
1. Turn off the concentrator by pressing the power button.
2. Remove the battery from the concentrator.
3. Lay the concentrator down on its side so that the underside is visible.
4. Press the latch button away from the columns to unlock the column assembly.
5. While holding the latch open, slide the column assembly out of the device by
pulling on the column pull handle.
6. Remove the columns completely from the concentrator.
Installation of the new columns:
7. Remove the dust caps from the new column assembly. Make sure there is no
dust or debris where the dust caps were located.
8. Insert the new column assembly into the concentrator.
CAUTION
9. Push the column assembly into the device until the spring-loaded latch button
fully returns to the closed position.
10. Plug in external power. Do not power on the concentrator.
11. Press and hold the plus (+) and minus (-) buttons for 5 seconds. The screen
will display "sieve reset".
12. Press the Mode button (bell symbol) once and screen will display "sieve reset
successful".

and PROPRIETARY
Do not leave the column ends exposed after the dust caps are
removed; they should be inserted into the concentrator as soon as
the dust caps have been removed to minimize environmental
exposure and maximize lifespan.
