Inogen RP-406 G4 Sieve Bed Kit (Columns)


This is a replacement Column Pair (sieve bed) 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.

We offer free sieve bed installation at all AZ MediQuip stores (for sieve bed purchased from AZ MediQuip).


A Column Pair (Sieve Bed) must always be in place when the InogenOne G4 is in use. Sieve Beds will wear down with normal 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 by showing a Low Purity or Low Oxygen message on the LCD screen.
