ResMed AirFit F30i Frame System (Frame + Cushion)

This is the ResMed AirFit F30i frame system: the mask frame, a full face cushion in the size you choose, and the quick-release elbow. Headgear is not included, so add our headgear separately if you need it.

Sizing works in two steps. First, pick your frame size: Small, Standard, or Large. Your frame size matches whatever F30i or X30i mask you already wear, and most people land on Standard. Second, pick your cushion size: Small, Medium, Small-Wide, or Wide. This is a separate, under-the-nose fit, so use ResMed's sizing guide if you're between sizes. There is no Large cushion; Wide is the largest option.

The frame is modular: any frame size pairs with any cushion size, so you can switch cushion sizes later without replacing the frame. This same frame also fits AirFit X30i cushions, not the standard AirFit F30. Need just the frame and elbow with no cushion? That's our frame only option.
