The kit includes the wrench to unscrew the hose that connects the cannula and 2 antibacterial filters. Without this accessory is impossible to carry out proper maintenance of antibacterial filters.
The antibacterial filter for Inogen One G2/G3 should be removed and replaced every 3 months to ensure maximum operating efficiency of the concentrator. Failure to clean can impair the functioning of the machine. The antibacterial filter should be replaced every time the device also is entrusted to a new patient.
