What’s the correct way to fit a mask?

Fitting a mask properly depends a great deal on your position. 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 sleeping position. Whether you sleep in a bed with no pillows or in a recliner, you should fit your mask in your usual sleeping position. If you experience difficulties in fitting your mask, please refer to your mask user guide for complete fitting instructions or discuss it with your care provider or equipment supplier.
