Column Pair (Sieve Beds) for Inogen at Home Oxygen Concentrators

4.50 Average Rating of 2 Reviews Read Reviews



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

USAGE: Column Pairs should only be replaced as needed. 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.

    Quick accurate service. The only potential concern was the manufacture date over 8 months prior, when shelf life is a concern. Product is working well at this point in time, yet service life will be a focus.
