Washable Diffuser Elbow Cover for F&P Eson 2 CPAP/BiPAP Masks

This Diffuser Cover, from Fisher & Paykel, snaps over the built in exhalation holes on the Eson 2 Nasal Mask’s elbow. It is an optional item that will reduce sound levels by approximately 10 dBA, and disperse exhaust to reduce airflow, when in place.
