Inogen One® G5® & Inogen® Rove 6 Replacement Column Pair

This is a replacement Column Pair designed for use in all Inogen One G5 & Inogen Rove 6 Portable Oxygen Concentrators. These removable metal columns contain the sieve beds used, by the InogenOne G5 and Rove 6, to convert normal air into air with high oxygen concentration. Columns Pairs should be changed as needed -- generally every 18-24 months.
