Be sure to ask the patient if they have observed any
malfunctions or changes in characteristics of the
equipment.
3.
Visually inspect the device, batteries, and accessories for
cracks or other damage.

Feel the sides of the device for vibration and listen for
unusual noises, rattles, or other signs that the device
requires service.
CAUTION
Discovery of cracks or other types of external damage may

Product Filter
This filter is intended to protect the user from small particles
in the product gas flow. The Inogen One G3 includes a product
filter, conveniently located behind the removable cannula nozzle
fitting. Inogen suggests that this filter be replaced between
patients.
To replace the Product Filter:
1.
Use the Cannula
Barb
Tool (available from Inogen as RP-
102) to access the product 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
G2.
2.
Carefully remove the
cannula
fitting by unscrewing it in
the counter-clockwise direction.
3.
The filter, a hard plastic disk with a silicone gasket
on its outer edge, 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 new 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.
WARNING
Failure to inspect and replace the product filter may
result in the filter becoming clogged or obstructed over
time, and in reduced delivery of oxygen to the patient.
