This Diffuser Cover snaps over the built in exhalation holes on the Brevida Nasal Pillows Mask elbow. It is an optional item that will reduce sound levels by approximately 5 dBA, and disperse exhaust airflow, when in place.
The Brevida Diffuser Cover is washable and reusable making it a great, eco-friendly, addition to any Brevida mask. It should be washed in warm, mildly soapy water, once a week and then rinsed and air dried before use. The Diffuser Cover should be replaced whenever it appears worn or damaged. For complete instructions review the documentation that came with your equipment.
