Choosing The Most Appropriate CPAP Mask For You

CPAP Masks

There are a wide variety of CPAP masks available to suit your unique face and preferred sleeping styles.

Finding the right CPAP mask for you is key to the success of your therapy. A well-fitted CPAP mask sits securely on your face, seals well under full pressure, performs in any normal sleeping position, is simple to refit at any hour of the night, and can be cleaned easily.

CPAP masks fit into 3 main categories:

Full Face Masks - A mask that covers your nose and mouth. They are a great choice for stability under higher therapy pressures, mouth breathers and for people with nasal obstructions.

Nasal Masks - A mask that covers your nose. Nasal CPAP Masks are the most popular choice for many CPAP users.

Nasal Pillows Masks - These masks fit directly into the base of your nose, with pillow type cushions that seal around your nostrils. They are light, small and quiet.

What’s the correct way to fit a CPAP mask?
Please note that your mask user guide also contains complete fitting instructions. In general, these factors will affect your fit:

CPAP Mask Position. The fit of a mask depends a great deal on your position: a mask that fits well when you’re sitting up might not fit so well when you’re lying down. This is because our facial muscles change when we lie down and relax even further when we’re asleep. It’s always best to fit the mask while you’re in your sleeping position: whether you sleep in a bed with no pillows or in a recliner, you should fit your mask in your usual sleeping position.

CPAP Mask Size. If you can only get a good seal by tightening the mask until it’s uncomfortable, then you may have the wrong size of mask. Please note that sizing across different masks is not always the same. Talk to one of our CPAP equipment specialist to be re-fitted with the correct size of mask.

CPAP Mask Headgear. Your mask should be as loose as possible while still creating a seal. If you feel your headgear strap is too loose or too tight, you should try re-adjusting it, or replacing your headgear if it is old or worn out.
