What does it mean if there is a sad face next to 'mask seal' in my Sleep Report?

This means that there is a high amount of air leaking from your mask.

This can be due to a poor mask fit or incorrect sizing.

Refer to your mask user guide for complete fitting instructions. User guides can be located here.
