The EasyFit Full Face Mask from DeVilbiss was designed after studying the facial profiles of 50,000 individuals from around the world. This study helped develop its unique, scallop-shaped cushion that provides excellent comfort. Combined with the lightweight and durable full face mask, this EasyFit Mask creates a superior fit and seal that won’t leak and irritate your eyes. The forehead support uses locking notches that enable you to easily change the angle and fit of the mask so you can optimize your comfort. This CPAP mask also features an exclusive ball-and-socket joint at the tubing connector that reduces hose tension to allow for greater freedom of movement – even for the most active of sleepers. The exhalation vent is incredibly quiet, and doesn’t direct the airflow to your face or your sleeping partner. This mask comes in 4 different sizes (small, medium, large, and extra-large), and also has been approved for multi-patient use.
