ResMed AirFit F40 Full Face Mask

The ResMed AirFit F40 is a compact full face mask whose soft silicone cushion rests beneath your nose and over your mouth, with no hard parts touching your face. It moves as you do, so the seal tends to hold when you roll over.

Night to night, the padded frame stays below your eyes, out of your line of sight. A short, flexible tube takes the drag off the mask, the vent keeps your breathing quiet, and magnetic clips let you take it off and refit it fast.

Key features:

• Smallest front-tube design: ResMed calls the F40 its smallest full face mask with the tube at the front, based on its own comparisons.
• Fits most faces: Three cushion sizes and three headgear sizes fit 98% of the faces measured in ResMed's studies.
• Easy from the start: In ResMed's home trials, every experienced CPAP user found the F40 easy to fit and adjust.
• Quiet for two: Its QuietAir vent ring disperses your breath softly, which ResMed designed with bed partners in mind.
• Bathroom breaks: The elbow unclips with two side buttons, so a trip out of bed doesn't mean taking the mask off.
• Licensed in Canada: Health Canada first licensed the AirFit F40 in August 2024, and its number appears under Specifications.

The AirFit F40 suits mouth breathers, side sleepers, and anyone who wants as little mask on their face as possible while still covering the mouth. For the tube on top of your head instead, look at the AirFit X30i or AirTouch F30i.

Note: Every F40 has magnets in the frame and lower clips, as ResMed offers no magnet-free version. Please contact us first if anyone in your bed uses a pacemaker, a defibrillator, or any implant sensitive to magnets.
