Column Pair for Inogen One G4 Portable Oxygen Concentrators

This is a replacement Column Pair designed for use in all Inogen One G4 Portable Oxygen Concentrators. These removable metal columns contain the sieve beds used, by the InogenOne G4, to convert normal air into air with high oxygen concentration. Columns Pairs should be changed as needed -- generally every 18-24 months.

A Column Pair (Sieve Bed) must always be in place when the InogenOne G4 is in use. Sieve Beds will wear down after prolonged use. In most cases G4 Column Pairs need to be replaced every 18-24 months; however in certain operating conditions earlier replacement may be required -- your G4 will let you know when it's time.

USAGE: Column Pairs should only be replaced as needed. When replacement is required the InogenOne G4 will alert you to the need with a Low Priority Alert reading "O2 Service Soon". This alert means that the columns should be replaced within 30-days. Column replacement is a simple process, that can be completed at home, without any special tools. For full instructions see the "Column Change Procedure" section of Chapter 6 of the InogenOne G4 User Manual. It is strongly recommended to purchase this item for immediate use, not for storage.
