Two filters are included ineachorder.
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.
