Updated July 2026 7 min read CPAP Mask Spotlight · UK Guide

Finding a CPAP mask that combines comfort, performance, and freedom of movement can be challenging. Many users want a mask that provides a secure seal without feeling bulky or restricting their sleep.

That's where the new ResMed AirFit™ F40 Full Face CPAP Mask stands out. Designed with ResMed's latest innovations, the AirFit F40 offers a modern full face mask experience with a compact profile, an ultra-soft AdaptiSeal™ silicone cushion, and a flexible frame that moves with you throughout the night — whether you're starting CPAP therapy or looking to upgrade from an older mask.

What's New About the AirFit F40?

A fresh approach to full face design.

Unlike traditional full face masks, the F40 has a minimal-contact design that helps reduce facial pressure while maintaining a reliable seal — and its compact construction gives users a wider field of vision.
