Nasal pillow CPAP masks are among the smallest and lightest masks available, covering just the nostrils with soft, cushioned inserts. They take up far less facial surface area compared to nasal or full-face masks, making them an excellent choice if you prefer a minimalist, low-profile design. Nasal pillows provide a comfortable, secure seal directly at the nostrils and allow for greater freedom of movement during sleep. These masks are especially popular with side and stomach sleepers, as well as users who experience claustrophobia or skin sensitivity from larger masks. With less facial contact and lightweight construction, nasal pillow masks often improve comfort and therapy compliance while delivering effective treatment.
