An easy fit for you

The AirFit F20 was designed to comfortably fit the widest range of faces. Indeed, in an international study, AirFit F20 fit 96.5% of all patients. The mask includes comfort features, such as the adaptive silicone cushion, which aim to provide a secure and comfortable seal for your therapy needs regardless of your face shape or size. 

Patient tested and preferred

Extensively tested and designed to give you the best therapy experience, AirFit F20 is a proven choice among patients. Recent studies have shown that, when comparing against the current market-leading full-face mask, 86% of patients prefer the seal of AirFit F20.

A majority of patients also say they prefer AirFit F20 over the current market leader in terms of stability and ease of use. These features combine to deliver a comprehensively superior mask experience.

With QuietAir, noise is minimized and airflow is so soft you might not feel it at all. You can simply enjoy a more peaceful night’s sleep and the freedom to sleep closer and more naturally with your partner.

Mask Sizing

You can print your ResMed sizing guide here. Remember to print to scale, as you’ll have to cut out your guide from the document you print.

If you prefer, we can also send you a sizing guide by mail, simply send us your posting details.

Once you have your sizing guide:

use a mirror and hold the sizing guide to your face. The top of the guide should correspond with the top of your nasal bridge.

the lower part of the guide indicates which mask size is best for your face. The size that aligns with the crease below your lower lip will be your best fit.

If you’re between sizes, we recommend selecting the larger option for greater comfort.

As an alternative to using a sizing guide, you can also use a straight ruler to measure the distance from the bridge of your nose (between your eyes) to the dip between your lower lip and your chin. Different measurements correspond to the following sizes:

Between 74-86 mm: Small

Between 86-98 mm: Medium

Between 98-110 mm: Large

Fitting Your Mask

Step 1 - Unclip the EasyClick Magnets.

Step 2 - With the mask held against your face, pull the headgear over your head. Ensure the top of the mask cushion is sitting comfortably at the top of your nasal bridge. The bottom of your headgear should settle comfortably at the top of your neck - with the top of the headgear sitting on your crown.

Step 3 - Bring each of the magnets up to meet their corresponding clips on the frame.

Step 4 - Adjust the tabs on the upper headgear straps.

Step 5 - Adjust the tabs on the lower headgear straps.

Step 6 - With your device still switched off, connect your device tubing to your mask elbow.

Step 7 - Connect the elbow to your mask.

Step 8 - To ensure your fit will work with your therapy: switch on your device and position yourself as if you are to begin therapy (e.g. lying down in bed).

Step 9 - Adjust your upper straps.

Step 10 -Adjust your lower straps.

Step 11 - Practice reseating your cushion – pull your mask away from your face, allow your cushion to reinflate, and then resettle the inflated cushion so the cushion membrane is sitting at the top of your nasal bridge.
