The ResMed Mirage FX has been a trusty favourite nasal CPAP mask for many years. As the mask gets older, we are finding there is a known issue with the ring that holds the elbow in place.

People will start to notice with an unusual increase in noise or performance from their CPAP mask.

To check whether the ringlet of your mask is ok, simply remove the elbow from your CPAP mask. Run your finger around the inlet give it a gentle pull to ensure that it is firmly in place.

What do I do if the ring has ripped from the cushion?

You can replace your cushion of the Mirage FX.

Alternatively there have been two ResMed nasal CPAP masks released since the ResMed Mirage FX, the ResMed AirFit N20 and the ResMed AirFit N20 Classic

What is the difference between these 2 masks?

The ResMed AirFit N20 is the first release of this mask. It has nothing in front of the eyes, and a nice sturdy headgear. It also uses magnets to secure it making it very easy to put on and off. In our clinic, it has taken over as our predominant nasal mask and we are getting positive reviews form this.

The ResMed AirFit N20 Classic is closer to the Mirage FX in its design. It uses the N20 cushion, but has a skinnier frame than the Mirage FX. The headgear of the AirFit N20 classic is also quite thin and lightweight compared to its counterparts. The N20 classic uses a similar ring and hoop system to the Mirage FX.

So if you have found an issue with the front of your Mirage FX mask, you can either replace the cushion or look to upgrade to a more modern mask. We have seen a smooth transition in our clinic from the Mirage FX to the ResMed AirFit N20 and AirFIt N20 Classic.
