ResMed AirFit F40 Full Face Mask

The ResMed AirFit F40 full face mask represents the future of CPAP therapy. Unlike the F20, which covers the bridge of the nose, the F40 uses an ultra-low profile design that leaves your line of sight completely open. It is engineered specifically for users who move frequently, allowing for comfortable side and stomach sleeping without the mask shifting.

Key Features & Benefits:

• AdaptiSeal™ Technology: The Resmed AirFit F40 Cushion is entirely made of soft silicone. It lacks a rigid plastic frame, allowing the mask to conform perfectly to your face, even at pressures up to 20 cmH₂O.
• Minimal Contact: By sealing under the nose, the F40 prevents the “Red Panda” marks on the bridge of the nose that are common with traditional masks.
• QuietAir™ Venting: The ring-shaped vent gently disperses air, making the AirFit F40 mask whisper-quiet for both the user and their partner.
• Magnetic Clips: Secure your fit in seconds with quick-snap magnets. (Note: Keep magnets 6 inches away from metallic medical implants like pacemakers).
• Short Tube Connection: The flexible short tube with a quick-release elbow allows you to move freely and disconnect for bathroom breaks without removing the whole mask.
• Soft Fabric Headgear: The Resmed F40 headgear is designed with four adjustment points for a secure yet gentle fit, preventing strap marks on the cheeks.

Can I use a ResMed AirFit F40 mask liner?

Is there a non-magnetic version of the F40?

Currently, the F40 is designed with magnets. If you have a pacemaker, ensure the clips are at least 6 inches away. Check our listings for the Resmed AirFit F30i non magnetic as an alternative if needed.

How do I clean my F40 mask?

Soak the cushion and frame in warm water with mild detergent daily. Squeeze the Resmed F40 headgear to remove excess water and let it air dry away from direct sunlight to maintain the silicone’s elasticity.
