Inogen One G5 Particle Filter

Replacement eco-friendly particulate filters keep dust, pet hair, and other airborne contaminants away from your oxygen. Removable particulate filters line the air intake screens to filter out dust, pet hair, and other airborne contaminants. They are washable and reusable, making them one of the eco-friendly features of Inogen concentrators. Users should wash and dry filters weekly (more often in very dusty environments) to help keep the concentrator working properly. Inogen recommends replacing the filter when it becomes deformed or the screen is damaged.
