The Evora Full Face CPAP Mask delivers full performance with minimal contact, allowing you to move and sleep freely without compromise. The mask has an under-the-nose seal that provides a clear line of sight, while the unique design of the seal keeps the mask comfortably in place. Not just that, but it also features a RollFit Seal, which is a dynamic rolling action that self-adjusts to the contours of the face, creating a secure seal with minimal pressure, improving the effectiveness of the oxygen therapy by reducing potential leaks.
