Inogen One G5 Particle Filter

The Inogen One G5 Particle Filter is a washable and reusable filter that covers the air intake screens to keep dust, pet hair, and other air-borne contaminants out of your oxygen. These filters are easy to clean – simply remove them and wash them in warm water with mild soap. Let them dry completely before putting them back on the concentrator. Inogen recommends replacing the filter when it become misshapen or when the screen is damaged.
