Note: This product cannot be shipped internationally, except for Canada. Sold and used as a pair, the removable Inogen One G4 Replacement Column Pair contains the sieve beds that convert normal air with lower levels of oxygen concentration to supply the patient with a high concentration of oxygen. Unfortunately, these sieve beds wear down after prolonged use and Inogen recommends replacing the columns every 18 months to two years (though in certain operating conditions, earlier replacement may be required). The G4 System will alert you when a replacement is needed and clear, easy-to-read, instructions make it easy to switch out the column pair without tools.
