Description
The Inogen At Home Replacement Column Pair (#RP-402) package includes both (2) columns in the package. Inogen recommends replacing the columns every 18 to 24 months for optimal performance. The removable metal columns provide a quick and easy way to service the Inogen At Home Concentrator without having to send in the product for repair. Clear step-by-step and easy to follow instructions are included with the package, enabling you to easily switch the column pair without any tools  and most beneficial - without having to send the Inogen At Home in for repair.
Since the columns are sold and used as a pair, the columns will also contain the sieve beds which convert the regular air into medical grade oxygen. These sieve beds wear down after prolonged use.
