ResMed's Quattro Air Full Face Mask with Headgear is the next evolution in their popular Quattro mask line. The minimal design makes it 45% lighter than the very popular Mirage Quattro. With only four parts it is easy to maintain and clean. The advanced design of the Spring Air cushion aims to create a secure seal with more comfort at the bridge of the nose. Together, the lightweight frame and cushion mean a more comfortable therapy experience.
