What are the benefits of the different cushion types?

The versatile DreamWear design lets you select a different mask type every night. You can use your full face mask when you have allergies or nasal congestion or find you are breathing through your mouth when you sleep.
Use the nasal cushions if the full face mask makes you feel claustrophobic or you need a higher-pressure setting.
Use the nasal pillows if you have a beard or mustache or breathe through your nose while you sleep.
