Elbow Diffusers with Cover

  • Brand:Fisher & Paykel
  • Part Numbers:400HC228

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.

  • Excellent right up to final delivery

    Web site is hard to work with. On the phone they were excellent. UPS delivered to the wrong house. This isn't CPAP Exchange fault but they should consider using competent delivery services.

  • Good product, shipping too expensive

    The product is good, but shipping such a small package via UPS is way too expensive. You should have an option to use USPS.
