"Mask seal" shows you how well your mask fits. Air leak increases if your seal is poor. If your leak is more than 24 L/min, adjust your mask fit.

The better your mask seal, the more points you get. This category can help you know if you need to adjust or change your mask to get a better fit. If your mask seal is poor, it can affect your comfort and the quality of your treatment. Your score reduces as your mask leak increases. You can get up to 20 points for minimal mask leak, 10 to 15 points for moderate leak, and 0 to 10 points for higher leak.

If you use a nasal or nasal pillows mask, it's important to remember to manage air that can leak through your mouth. Mouth leak can give you a dry mouth and affect your therapy.
