The particle filter is designed to filter out large particles with ≥95% efficiency so that the air you breathe is as clean as the air around you. 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.
