ResMed Airfit P30i Nasal Pillow MaskResmed Airfit P30i Nasal Pillow Mask is designed to feel more natural, with the tubing connection at the top of the head. This allows for more sleeping positions with the tubing out of the way and out of sight. The P30i also features QuietAir vent technology which gently breaks up exhaled air so it spreads out lightly and quietly. The new SpringFit frame has small built in ridges which flex and work together with the size and contours of your face.
