This Diffuser Cover snaps over the built in exhalation holes on the Eson 2 Nasal elbow. It is an optional item that will reduce sound levels by approximately 10 dBA, and disperse exhaust to reduce airflow, when in place.
The Eson 2 Diffuser Cover is washable and reusable making it a great, eco-friendly addition to any Eson 2. 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 full usage instructions please review the user manual that came with your item.
