Slip into sleep with the ALL NEW ResMed AirFit F40! The F40 is an ultra-compact full face CPAP mask designed to provide comfort and freedom throughout the night with reduced pressure on the nose. This innovative mask offers a soft silicone cushion and a low-profile structure, allowing you to sleep in any position and move freely.

100% Universal Fit

In a ResMed external clinical study, the AirFit F40 achieved seal and comfort for 100% of patients surveyed, ensuring a snug fit without compromising comfort.

Ultra-Compact Design

The AirFit F40 offers minimal facial contact and maximized comfort thanks to the under-the-nose cradle fit, which reduces bulk, limits feelings of claustrophobia, and keeps an open line-of-sight for your bedtime wind-down.

Easy On-and-Off Magnetic Headgear

The magnetic clips allow for quick and easy fitting or removal of the mask, reducing hassle before bedtime and upon waking. A redesigned quick-release elbow also makes it easier than ever to quickly disconnect for middle-of-the-night bathroom trips.

AdaptiSeal Cushion

The AdaptiSeal silicone cushion adapts to your facial contours, providing comfort and maintaining an effective seal throughout the night.

Flexible Frame Moves With You

The fully flexible frame, covered by soft nylon fabric padding, sits below the eyes for comfort and reduced facial marks. It allows for easier movement during sleep without compromising the seal.

Short Tube Reduces Hose Pulling

The short tube reduces drag and moves with you, providing the flexibility to sleep comfortably in any position and ensuring continuous therapy.

Product Manual: AirFit F40 User Guide

Product Sizing Guide: AirFit F40 Sizing Guide

Using Your Mask for the First Time

Connect the CPAP hose to the mask elbow
Release elbow from the frame by squeezing the quick release tabs
Ensure headgear clips are detached from the frame
Hold the cushion in place under your nose and over your mouth
Pull the headgear over your head
Attach the lower headgear straps using the magnetic clips
Adjust the upper and lower head straps until the mask fits comfortably
Reattach the elbow and hose to complete assembly

Magnetic Clip Warning

This mask uses magnetic clips to secure the frame into place without having to adjust the mask’s velcro head straps. These magnets are not safe when used with certain medical implants including:

Pacemakers,
Implantable Cardioverter Defibrillators (ICD)
Neurostimulators
Cerebrospinal Fluid (CSF) Shunts
Insulin/Infusion pumps
Aneurysm Clips
Flow Disruption Devices
Embolic Coils
Stents
Valves
Electrode
Hearing Aids

Mask Safety Features

The mask has two main safety features, exhaust vent holes and anti-asphyxia valves, which ensure normal breathing and proper exhalation. Avoid blocking these vents to maintain safety and therapy quality. Regularly inspect these areas to ensure they remain undamaged and free of obstructions.

Finding Your Perfect Fit

The AirFit F40 is available in three frame sizes, including small, standard, and large. Most people fit into the standard size, so it's best to start with this headgear and then order the small or large size if necessary.

Cushion sizes are offered in small-wide, medium, and large. If you do not know your cushion size, we suggest ordering an AirFit F40 Starter Pack, which comes with all three cushion sizes, so you can test them out. You can also check out the sizing guide linked above.

Selecting Your Cushion Size

If you currently own an AirFit F40 and are looking to re-order your current mask size, you can find your mask's cushion size by checking the plastic shell of your mask cushion. On this cushion, you will see an SW, M, or L indicating the size of your cushion.
