3.1.6. Output Filter Replacement
This filter is intended to protect the user from small particles in the product gas flow. The
Inogen One G5 includes an output filter conveniently located behind the removable
cannula nozzle fitting. Inogen suggests that this filter be replaced between patients.
Use the Output Filter Replacement Kit to replace the Output Filter:
1. Use the Cannula Barb Tool (included in RP-404) to access the output filter.
The tool has two prongs which mate with two indentations located on the
surface of the metal cannula barb fitting on the Inogen One G5.
2. Carefully remove the cannula fitting by unscrewing it in the counter-clockwise
direction.
3. The filter, a thin white disk, will be visible in the recess once the hose barb is
removed.
4. Remove the filter, and inspect the recess to make sure it is free of debris.
5. Install a replacement filter.
6. Carefully screw the cannula barb fitting back into the recess (clockwise) until it
bottoms out on the filter gasket. Take care to squarely screw the nozzle fitting
into the threads, and not to over tighten.
CAUTION
3.1.7. Oxygen Purity Check
The oxygen concentration can be checked using the Salter Labs PrO2 Check ultrasonic
oxygen analyzer. The concentrator should be run for 10 minutes before measuring the
oxygen concentration. If the concentrator has not been used for more than 2 weeks, the
concentrator should be run for a minimum of 30 minutes to allow for adjustments to the
operating parameters prior to measuring the oxygen concentration.
3.1.8. Data Log
Operating data from your Inogen One G5 concentrator are periodically recorded to flash
memory located within the device. Data is stored for a period of approximately 6-12
months; new data replaces the oldest data as it is collected.
Additionally, the device records errors and system information at the time of the error
which is useful in diagnostics.

have any concern over the safety of the device, arrange for equipment
servicing.
Failure to inspect and replace the product filter may result in the filter

oxygen to the patient.
