Fitting your CPAP mask isn’t just about comfort – it’s about ensuring you receive the full effect of your therapy to improve your sleep quality long term. 

A CPAP mask that doesn’t fit properly can lead to leaks and discomfort, making you less likely to use your mask consistently.¹

In this guide, we look at how to choose the right style and size of the mask, put it on properly, and troubleshoot fitting issues.  

How to get the perfect CPAP mask fit

Finding the perfect fit for your CPAP mask may seem complex, particularly when starting therapy. Your breathing style, sleep position and facial features can change the fit and seal of your mask.¹ 

Because everyone has different needs, a wide range of mask styles and sizes are available. Each has its own fitting process – some may need more adjustment to help you achieve the perfect fit.

Choose the right type of mask 

There are several types of masks to choose from and finding one to meet your needs comes down to individual preferences. 

A full-face mask sits over your mouth and nose, with straps typically around your head and chin, while a nasal mask sits on the bridge of your nose and usually attaches around your head.¹ Oral masks fit in and around the mouth.²

Get the right size

Aside from nasal pillows, most CPAP masks come with sizing guides and mobile apps designed to assist purchasers with achieving the right fit. For example, F&P Healthcare has sizing guides for most of its masks to remove the sizing guesswork for wearers. View our product care resources to access available sizing guides.

How to put your mask on correctly 

The way you put your mask on can make a difference to the quality of the fit. Practice putting on your mask during the day rather than waiting until you’re tired right before bedtime. Below are some steps to ensure a good mask fit:³

1. Loosen the straps, place them over your head and then tighten them gradually. 
2. Ensure your mask sits comfortably on the face – not too high or too low. 
3. Check that you can get one finger under each strap – loosen if necessary.
4. Practice putting your mask on in front of a mirror and ensure that the headgear is adjusted to the same setting on each side. 
5. Lie in your preferred sleeping position to make final adjustments.
6. Test the mask using the device with pressure to check for air leaks.

Achieve a secure seal 

If your CPAP mask leaks, you may not get the full benefit of your treatment.¹ Troubleshooting includes tweaking the fit, trying different mask sizes and styles, and working with your doctor, specialist, or sleep health provider.

Avoid over-tightening straps 

A too-tight mask can distort the shape of components and cause leaks.¹ Instead, aim for a snug but comfortable fit. Modern masks such as F&P Solo™ solve the tightness issue with straps that stretch to fit and remain securely in place to prevent mask movement during sleep. 

Choose a comfortable mask 

While everyone has different preferences, slim, compact masks with fewer straps and components can be more comfortable with less surface area contact around the face and may also be easier to use.¹ 

Pick non-irritating materials 

Choosing a mask with high-quality materials and construction is important. You may wish to avoid open seams, irritating materials, or rigid plastic against your skin. 

Keep your machine, mask and face clean 

Bacteria on your face, mask or CPAP machine can cause skin irritation.⁴ Avoid the issue by washing your face before bed and regularly cleaning your mask, components and CPAP machine.  

Try different masks 

If you’re having issues with fit or comfort, work with your health professional to try a range of masks – a new size or style could be better for you.⁴ 

Use a barrier on your skin 

Avoid mask irritation by using a barrier cream, mask liner or gel pad between your mask and your face.⁴  

Signs your CPAP mask is fitted incorrectly⁴

Your mask leaks air 

If you can feel air moving around your eyes, nose or mouth, your CPAP mask could be leaking.

Your mask is noisy 

This can be a sign of an insecure seal and air draft. 

Your mask hurts 

Feeling physical pain during or after mask-wearing could mean the fit isn’t quite right. 

You wake up with excessive lines, red marks or bruises 

These show that your mask may be too tight in certain areas, which could mean you need a new size, style or looser fit.
