How to fit your mask

Properly fitting your mask is an essential step toward comfortable therapy. ResMed answers your most frequently asked mask fitting questions below.

Q. What’s the correct way to fit a mask?

A. If you experience difficulties in fitting your mask, please refer to your mask user guide for complete fitting instructions. 

Facial muscles change when we lie down and relax even further once we're asleep, so it's always best to fit the mask while you're in your usual sleeping position. 

Q. How can I keep my mask on at night? I often remove it while I'm sleeping without realising it.

A. As each individual adapts to their therapy differently, there may be various contributing factors requiring a personalised approach. You should discuss this with your local ResMed accredited outlet or your doctor. 

Q. Do I have the right mask size? I have to strap it so tight to obtain a seal that it hurts.

A. It's important not to over-tighten your mask. Doing so may be a sign that you have the wrong cushion size or an incorrectly adjusted forehead support. If you're using a ResMed mask that has a MicroFit dial, it's important to note that your clinician has set the dial at the optimal position and adjusting it significantly from that position may cause discomfort. If you experience difficulties in fitting your mask, please refer to your mask user guide for complete fitting instructions or discuss this with your local ResMed accredited outlet or your doctor.

Q. My mask is leaking. What does this mean?

Refer to the troubleshooting section in your mask user guide. Mask leak may indicate one of several things, including:

  • incorrect adjustment
  • incorrect assembly
  • incorrect size
  • your mask is worn out and needs replacement

Contact your local ResMed accredited outlet to determine if one of the above factors is interfering with the proper fitting of your mask.
