Replacement Cushion for Fisher and Paykel Eson Nasal CPAP Mask

With RollFit technology, Fisher and Paykel improves the seal and comfort of your Eson Nasal CPAP Mask. By rolling on the bridge of your nose during CPAP therapy, the Eson will allow for an enhanced freedom of movement so that you can change positions frequently during CPAP therapy without experiencing mask drag on your face, or having negative effects on the seal around your nose. This replacement cushion will allow you to extend the life span of your Eson Nasal CPAP Mask without requiring you to purchase a brand new mask.

Three Different Sizes

You can purchase the cushion in either the small, medium, or large size. The medium and large sized cushions will fit with the same size of headgear, but the small will require the small headgear. If you are attempting to change cushion sizes to better increase your comfort or the seal, you need to know what size of mask you purchased originally so that we can ensure that the new cushion size will fit with your headgear.


The mask rolls on the bridge of your nose increasing the comfort and the performance while undergoing CPAP therapy. The rolling technology allows for a better seal reducing or eliminating leaks, while also allowing for you to move during use without experiencing any type of mask drag or breaking the seal.

Air Diffuser

The air diffuser uniquely locates the exhale ports so that your mask is ultra-quiet during use. Air will flow away from you and your partner with minimal sound so that you can both rest peacefully throughout the night without being interrupted by similar CPAP masks that are much louder.

Key Features

  • Three different sizes - Small, medium, and large to provide versatility with your fit
  • Compatible with headgear - Medium and large cushions work on the same size headgear, small cushions work on the small headgear
  • RollFit - Rolls on the bridge of the nose to allow for an expanded freedom of movement and comfort


Reviewers Tip:

The Eson Nasal CPAP Mask is easy to dissemble and clean as there are only three parts. You should clean the cushion every day as the oils of your skin can cause cushions to break down over time.

Using your Fisher and Paykel Eson Nasal CPAP Mask


If I change cushion sizes to I need a new headgear?

It depends, if you are switching between medium and large you do not need a new headgear size as the medium and large cushions fit on the same size headgear. However if you are switching between a small and either medium or large you will need the small headgear size in order for the cushion to fit.

What kind of supplies do you recommend for cleaning the cushion?

We sell several different sprays and wipes amongst other things that will help with cleaning your cushion. We recommend that you clean your mask, specifically the cushion, daily in order to prevent the oils from your face causing the cushion to break down and require a replacement earlier than normal.

The Eson could possibly be the best mask i have purchased so far, so i purchased a spare Cushion just in case as they are over double the price here in Australia, buy them when i order something bigger and its worth it.
