Column Pair (Sieve Beds) for Inogen One G5 Oxygen Concentrators


A Column Pair (Sieve Bed) must always be in place when the InogenOne G5 is in use. Sieve Beds will wear down after prolonged use. In most cases G5 Column Pairs need to be replaced every 18-24 months; however in certain operating conditions earlier replacement may be required -- your G5 will let you know when it's time.

USAGE: Column Pairs should only be replaced as needed. When replacement is required the InogenOne G5 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" in your the InogenOne G5 User Manual. It is strongly recommended to purchase this item for immediate use, not for storage.
