Traditional full face masks completely cover the nose and the mouth. This allows users the option to breathe through either.
Some full face masks include a forehead stabilizer that helps improve the cushion seal for active sleepers. The headgear typically
provides four points of contact for stability and making adjustments more easily.
Though sometimes considered "bulkier" than other masks, some users prefer them because the wider surface area helps spread the air pressure out to make CPAP therapy more comfortable. Some manufacturers have recently redesigned their full face masks to sit underneath the user’s nose. These designs greatly reduce facial contact and eliminate the feelings of claustrophobia some full face users experience.

Full Face CPAP Masks Are Best For:
o Mouth breathers
o Back sleepers
o Those with nasal congestion problems
o Users with prescriptions that require a higher pressure setting

Nasal masks fit over your nose only, offering a lighter fit than full face masks. Nasal masks are smaller than full face masks and cover or cradle the nose. Usually, they are triangular or oval shaped to sit just around the nose. It is held in place by headgear that goes around the rest of a user's head. These masks offer minimal contact with the face while still creating a secure seal and stable headgear. A nasal mask is best suitable for users who naturally breathe through only their nose, and not their mouth.
Nasal masks deliver indirect airflow to your nasal area, but not directly into your nostrils like a typical nasal pillow mask would. This type of mask can also sustain a higher pressure setting than a nasal pillow mask. Additionally, users who
experience claustrophobia with full face masks may want to try a nasal mask as they are traditionally less bulky.

Nasal CPAP Masks Are Best For:
o Users with prescriptions that require a higher pressure setting
o Active sleepers
o Users with unique facial shapes

Even more lightweight and minimal than nasal masks, offering a high level of openness and visibility. Nasal pillow masks sit underneath the nose and use two soft pillows that sit inside the nostrils to provide direct airflow. The pillows slightly inflate to create a secure seal and comfortable therapy into the airflow. The unique and slim shape of nasal pillow masks allow for a less intrusive feel on the face, but still deliver effective performance.
This type of mask also is great because having it directly inside a user's nostril minimizes the risk of potential air leaks throughout the night. They offer a much more minimal design than traditional full face and nasal masks. Similar to nasal masks, this type of mask is particularly suitable for users who do not breathe through their mouth and only their nose.
Some users, however, do not like the feeling of the cushion sitting inside their noses. This direct airflow may also dry out a user’s nasal passage more quickly than other masks.

Pillows Masks Are Best for :
o Users who find full face masks claustrophobic
o Users with facial hair
o Users who wear glasses and wear their mask while watching TV or reading
o Users who prefer the smallest CPAP mask.
