The ResMed AirFit F30i is an under-the-nose full face CPAP mask with a silicone cushion and a tube that connects at the top of your head instead of at your chin. It covers your nose and mouth, runs at therapy pressures of 4 to 30 cm H2O, and ships as a complete system in three frame sizes (Small, Standard, Large) and four cushion sizes (Small, Small-Wide, Medium, Wide).
Because the tube sits above your head, it stays clear whether you sleep on your back, side, or stomach, and the UltraCompact cushion seals under your nose instead of over the bridge, so glasses, reading, and TV before bed are not blocked. The lower headgear clips are magnetic for a quick, secure fit (see the safety note in the FAQs if you or a bed partner has an implanted medical device).
The AirFit F30i, AirTouch F30i, and AirFit X30i share the same tube-up frame, so you can switch to a fabric-covered cushion or a hybrid nasal-and-mouth seal later without buying a new frame. We carry the cushion, frame, and headgear separately, and our full AirFit F30i review covers fit and comfort in more depth. A valid prescription is required; compare it against the rest of our full face masks if you are still deciding.
