There are several types of CPAP masks that can be used to deliver continuous positive airway pressure (CPAP) therapy to treat sleep apnea. The most common types of CPAP masks include:

1. Nasal masks: These masks cover the nose only and are held in place with straps that go over the head and around the back of the neck. They are suitable for people who breathe mainly through their nose.

2. Nasal pillow masks: These masks have two small pillows that fit just inside the nostrils and are held in place with headgear. They are a good option for people who find nasal masks uncomfortable or claustrophobic.

3. Full-face masks: These masks cover the nose and mouth and are held in place with headgear. They are suitable for people who breathe through their mouth or have nasal congestion.

4. Oral masks: These masks fit over the mouth and are held in place with straps that go around the head. They are suitable for people who breathe mainly through their mouth.

5. Hybrid masks: These masks combine the features of a nasal mask and a nasal pillow mask and can be used by people who breathe through their nose and mouth.

6. Total face masks: These masks cover the entire face and are held in place with headgear. They are suitable for people who have a lot of facial hair or who find it hard to get a good seal with other types of masks.

It is important to choose a mask that is comfortable and fits well, as this will help ensure that you are able to use it consistently and get the maximum benefit from your CPAP therapy.
