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.

First, I must convey my appreciation to Respshop for their helpful and speedy service, particularly as I live in Thailand.

Regarding the Quattro FX cushion, I go through these very quickly - it is a Catch 22 situation where I have a number of different masks, but the Quattro FX is the most comfortable for me and I find the others uncomfortable or cumbersome.. However, the cushion is prone to leaks and, even though Resmed state that you do not need to make the mask tight, I find that this is not possible and have to make the mask quite tight. Apart from sleep apnea, I suffer from COPD and chronic sinusitis and have recently undergone lung cancer surgery, so a leaking mask is a hazard for me. Therefore, it is a case of either putting up with a mask that is uncomfortable or continuously purchasing Quattro FX mask cushions regularly. You only have a rating from bad to good, but I would suggest that the mask itself is good, but the cushion material does not give good service. However, this review is to rate the cushion so I give it a halfway mark.

Perfectly fine with me!!! As a matter of fact, I am ordering my fourth replacement cushion today using the summer promotion. Been using CPAPs since '95 and only began the full-face model in November 2011. Once I settled on the Medium size all was fine. Had started with the Large and that was a problem with air on the eyes and this was just after having lasik surgery. I like the brand and would recommend. Nothing in the CPAP world is perfect but this is as close as it gets for me.

I like Quattro FX Mask and Cushion. I have found if you use the RemZzzs CPAP Mask Liners, I get up to 6 months out of the Cushion before I have to replace them. I clean my each day only using Cleanzex Unscented CPAP Mask Wipes, and once a month I do a good wash in soap and water. I have tried a number of mask before I came across this one, and they are the best one I very had...

I agree completely with your other l customers , these cushions must be the worlds most expensive plastic, but try buying the same item in Australia , they are at least 50% more expensive here, 79 Australian dollars I was quoted today, for an item they recommend you change fortnightly. enough said.

This mask is not worth the amount they are charging for it! It doesn't last more tha 2 months! should cost only about $10 for the time it lasts! Absolute ripp off! Please give us a break and reduce the price!

These do not last very long and are quite expensive. I have just purchased the AirFit F10 mask to see if I get better wear and comfort. However, the FX is less claustrophobic and much better for reading

I have a resmed mirage quattro mask (61203). What is a cushion replacement I need ? thanks
Hi there, this is not the replacement cushion for your mask. You require the large cushion replacement for the Mirage Quattro which can be found here: (Model # for size Large is: 61293)
