AirFit™ F40 Quiet – ResMed Full Face Mask

The AirFit™ F40 Quiet by ResMed is a next-generation full face CPAP mask designed to deliver reliable therapy with exceptional comfort, minimal noise, and a low-profile fit. Ideal for individuals who breathe through the mouth or require higher pressure settings, the F40 combines innovative engineering with user-focused design to make sleep therapy more comfortable and less intrusive.


Key Features

Ultra-QuietAir™ Vent Technology

The F40 Quiet features advanced QuietAir™ diffused venting, gently dispersing exhaled air to significantly reduce noise and airflow disturbance. This creates a quieter sleep environment for both the user and their partner.

Full Face Coverage, Low Profile

The mask covers both the nose and mouth, ensuring consistent therapy even if breathing patterns change during sleep. Despite being a full face mask, its compact, low-profile design reduces facial bulk and improves comfort.

Adaptive Cushion Technology

The soft, flexible cushion is designed to conform smoothly to the face, helping deliver a secure seal while minimizing pressure points and leak risks—even with movement during the night.

Lightweight & Minimal Contact

Built with lightweight materials and a streamlined frame, the F40 reduces facial contact and helps prevent skin irritation, making it ideal for regular, long-term use.

Easy Fit & Adjustability

The adjustable headgear provides a customizable, stable fit, allowing users to find the right balance of comfort and performance with minimal effort.

Compatible with Standard CPAP Systems

The AirFit F40 Quiet works seamlessly with most CPAP, APAP, and BiPAP machines, making it a versatile choice for a wide range of therapy setups.


Who It's For

  • CPAP users who breathe through both mouth and nose
  • Individuals sensitive to mask noise or air drafts
  • Users seeking a modern, low-profile full face alternative
  • Side sleepers needing flexibility and stability
