Extend the life of your CPAP mask with replacement cushion

The cushions for the ResMed Quattro FX CPAP Full Face Mask may need to be replaced periodically. Select the appropriately sized cushion to fit your mask.


The Quattro FX comes in three different sizes, with face cushions built to accommodate each size. Replacement cushions will only fit in masks that are the same size. Large frame masks require a large cushion, medium frame masks a medium cushion, and small frame masks a small cushion.

Cushion Design

The cushion's dual-wall design serves two purposes: the inner wall supports and stabilizes the cushion, while the outer membrane seals around your face. The outer membrane inflates while you breathe, allowing it to remain sealed without stretching across your face and causing sores or red spots.


  • Dual-wall design
  • Comfortable fit without stretch marks or sore spots
  • Inflatable mask expands while you breathe for maximum comfort with minimal disruption

Reviewers Tip:

Replace your cushion every three months or so to ensure that the mask doesn't leak or slip off.

Fitting Your ResMed Quattro


I bought a replacement mask but can't get it to fit.

Face cushions are designed to fit only one mask size. If your replacement cushion does not fit, check to make sure that you ordered a properly sized cushion.

How often should I replace the cushion?

As long as your mask remains sealed, your cushions are probably in working order. When you notice your cushions start to sag, they need to be replaced, as they will no longer fit around your face and will emit air. Cushions will generally need to be replaced after roughly three months of use.
