Welcome to Apex Oxygen, our goal is to bring you the best performing replacement columns at the best price. We offer re-poured replacement columns for your Inogen G3 oxygen concentrators, using the best available technology.  If you are looking to replace your worn out factory columns, we can provide an upgrade for  longer lasting oxygen without the high cost, on an exchange basis. At this time, we are concentrating only on the G3 columns.

                   Apex Oxygen will also buy your used Inogen G3  columns in any quantity. We have Quantity commercial programs for DME, HME providers.  Please contact us for more information.

                   We are a licensed company located in Houston, Texas and serve US and Canadian customers only at this time.
