These filters slot in between the Diffuser Cover and the Elbow on all Eson CPAP/BiPAP Masks. When in place the diffuser will lower the sound level of any Eson Series Mask by approximately 8 dBA!


This package includes 10 diffusers as well as a diffuser cover.

Usage Information: The Diffuser Filter and Elbow Cover are optional items which help to make the Eson Nasal Mask extra quiet. Diffusers are not required for proper operation of the mask.
