Inogen One G4 & G5 Output Filter Kit

With the Inogen One G4 & G5 Output Filter Kit, you won’t have to worry about breathing in airborne particles. It comes complete with two replacement output filters, compatible with the G4 and G5 portable oxygen concentrators. The kit also includes a spanner wrench, which has two prongs to help you access the output filter behind the detachable cannula barb fitting. 

Inogen recommends replacing the filter between patients. To do this, follow these instructions:

• Using the spanner wrench, carefully unscrew the metal cannula nozzle fitting in a counter-clockwise direction.
• Remove the old output filter and clean the dirt off the recess.
• Insert the new output filter.
• Carefully screw the cannula nozzle fitting back into the device in a clockwise direction. Avoid overtightening the screws.
