For mouth breathers, a full face CPAP mask is typically the best option. This type of mask covers both the nose and mouth, ensuring effective therapy even if you breathe through your mouth during sleep. Full face masks provide a secure seal and consistent airflow, making them ideal for individuals with nasal congestion or those who struggle to keep their mouth closed. They offer comfort, stability, and optimal performance, helping you achieve restful, uninterrupted sleep throughout the night.
