Mask Fitting Tips

Proper mask fitting is essential in improving the quality and comfort of your therapy. If your mask does not fit properly, you may experience discomfort and your therapy will not be as effective. Follow these links for suggestions on ensuring that your mask fits comfortably while providing an optimal seal.

*Note: ResMed masks must be sized in the sleep position using the appropriate ResMed sizing template for the respective mask. If the mask is the wrong size, proper fitting is unlikely. Please check with your dealer if you have concerns about proper fitting. You may also refer to our sizing templates, which are available in the Products section or by clicking here.
