This unique, soft, silicone frame from ResMed is designed for use with all AirFit F30i CPAP/BiPAP Masks. Because the frame is soft it adapts naturally to facial contours without pinching or pressure points; and it will accommodate almost any sleeping position. Three frame sizes -- Small, Medium & Large -- are available.
Usage Information: Frames for the F30i mask are available in three different frame sizes; Small, Medium & Large. Most users will prefer the Standard frame regardless of their cushion size.
