ResMed N30 Nasal Mask Details The N30 Mask is one of ResMed's latest and greatest creations. It takes the comfort of a nasal cradle cushion and places in the minimalist form factor of their P10 Nasal Pillow Mask range. This mask would be great for PAP users that prefer a minimalist approach to their treatment. It is also a great option for side sleepers as it doesn't have a cumbersome frame or headgear that some find uncomfortable during the night, or that may cause marks on their face in the morning.

The nasal cradle design virtually eliminates any soreness experienced from pillow style masks. The N30 mask is easy to slip on and off when going to bed and during the night, so this is one to consider if you frequent the bathroom or have children that cause you to wake frequently during the night. The tension for the headgear can be further adjusted with clips the hold the excess strap.
