Designed to make sleeping in any position easier, including on your side or stomach, the ResMed AirFit N30i is now newly updated to offer ResMed QuietAir diffused venting technology and a soft, flexible silicone cushion that flexes and adapts as you move around. No front-end tube means the mask stays out of sight and out of the way so you can sleep closer to your bed partner. The SpringFit frame offers a personalized fit, and a quick-release elbow makes it easy to disconnect the mask from the tubing if you need to get up during the night.
