G3 Replacement Particle Filters (Flow Setting 1-5)

For Inogen One G3 System Flow Setting 1-5: These replacement filters are ONLY compatible with Inogen One G3 systems with a FLOW SETTING range between 1-5. If your replacement filters are found on the top two of the four vents, this option is for you. Two filters are included in each order.  Wash and dry the filters weekly (more often in very dusty environments) to help keep the concentrator working properly. Inogen recommends replacing the filter when it becomes misshapen or when the screen is damaged.  Replacement filters for our portable oxygen concentrators are sold in packs of two.
