How to Size the AirFit N30i and Choose the Right Cushion

The ResMed N30i has two frame sizes (Standard and Small). Each pack includes three cushion sizes.

The specific design of the mask means each size cushion easily clicks into the same frame, so you can swap between them with ease.  As a guide - Start with the small pack for female patients and the standard pack for male patients. The cushion sizes are the same in both packs.
