What does LEAK mean on my SEFAM DreamStar Humidifier?
- MMr. Andre DiazSep 2, 2025
If 'LEAK : ++ (or +++ or ++++)' is displayed on the screen of your SEFAM Humidifier, it means the device has detected a high level of leak. Adjust your mask, mask cushion, and/or harness until you achieve a good mask fit.
