Nasal pillows masks are a compact and lightweight option designed for minimal contact with the face. They work best with prescriptions of low-to-moderate pressure settings, since airflow that is direct to the nostrils may be uncomfortable at high settings. Nasal pillows masks are ideal for those who toss and turn in their sleep or sleep on their side/ stomach. They are also suited for those who experience claustrophobia when wearing larger masks or have a lot of facial hair.
