The Inogen G3 Replacement Column Pair comes with two additional columns.
Warranty: 1 Year.
Serving as the quickest and most efficient way for you to service your Inogen One G3 System without having to send it in for repair, an Inogen G3 Replacement makes it easy for you to switch out the column pair without the need for tools. Sold as a pair, the columns contain the sieve beds that convert normal air with lower levels of oxygen concentration to medical grade oxygen. Unfortunately, the sieve beds wear down after periods of prolonged use, hence the need for replacements. Inogen recommends replacing your columns approximately every 18 months, though certain operating conditions may necessitate earlier replacement.
