ResMed AirFit F40 Full Face CPAP Mask

Lightweight, Low-Profile Comfort with a Secure Under-the-Nose Seal

Experience comfortable and effective CPAP therapy with the ResMed AirFit F40 Full Face CPAP Mask, designed for users who prefer a lightweight, low-profile mask with minimal facial contact. Featuring the innovative AdaptiSeal™ under-the-nose cushion, the AirFit F40 delivers a secure seal while enhancing overall comfort throughout the night.

Its ultra-light 20.4 g flexible frame naturally adapts to your movements, while the QuietAir™ venting system minimises noise and gently diffuses exhaled air for a quieter sleep environment. Magnetic headgear clips make fitting and removal quick and effortless, while the integrated short tube and quick-release elbow allow for greater freedom of movement and easy disconnection when needed.

Important: This mask contains magnets that may interfere with certain implanted or nearby medical devices. Please review the user guide carefully to ensure safe use before starting therapy.

Key Features

AdaptiSeal™ Under-the-Nose Cushion
Ultra-soft silicone cushion provides a secure seal without placing pressure on the bridge of the nose, helping reduce irritation and red marks.
Ultra-Lightweight Frame (20.4 g)
Weighing just 20.4 g, the flexible frame offers a barely-there feel while maintaining a stable and comfortable fit throughout the night.
Soft Fabric-Covered Frame Arms
Gentle, fabric-covered frame arms improve comfort and support natural movement, making the mask ideal for side sleepers.
QuietAir™ Vent Technology
Advanced venting system quietly disperses exhaled air, reducing noise for a more peaceful sleep environment for you and your bed partner.
Magnetic Headgear Clips
Four-point adjustable headgear with magnetic clips allows for quick fitting, effortless removal, and consistent positioning every night.
Quick-Release Elbow
Disconnect from your CPAP tubing effortlessly without removing the mask, making nighttime interruptions more convenient.
Low-Profile Open Design
Compact, minimal-contact design leaves your field of vision clear for reading or watching TV before bed — without the bulk of a traditional full face mask.
Complete Mask System
Includes the frame, AdaptiSeal™ cushion, adjustable headgear, quick-release elbow, and short tube — everything needed for effective CPAP therapy right out of the box.

Q2. Is this kit compatible with all CPAP masks?
A. No. This kit is designed specifically for AirFit™ F40-style full face mask systems and is not compatible with other CPAP mask models.
