Product Description

The Eson diffuser filters, sold here as a 10 pack with an elbow cover, keep the original Fisher and Paykel Eson nasal mask running quietly, and CPAP Supplies Canada ships them to Eson owners across Canada. The filters use several thin layers to diffuse exhaled air so it leaves the mask softly rather than in a noisy jet.

Why choose these Eson diffuser filters?

  • Ten in a box. A full pack of replacements plus the cover, which is roughly ten months of therapy at one filter per month.
  • Quieter exhale. The layered material minimizes exhalation noise and draft for you and a bed partner.
  • Genuine F&P part. Part 400HC228, sized precisely for the Eson elbow.
  • Easy to change. Slide the old filter out and drop a new one in under the cover.

Replacement schedule

Change the filter about once a month, or sooner if you have been ill or notice the mask getting louder. Rinse and dry the reusable cover as part of your regular mask cleaning.

Frequently asked questions

Do these fit the Eson 2?
These are made for the original Eson mask. The Eson 2 uses its own diffuser, so order that version if you have the newer mask.

Is the cover included?
Yes. The pack includes the reusable elbow cover along with ten diffuser filters.
