Optimising mask seal and comfort
To receive effective therapy it is important to have the best seal possible between your mask and your face. If you are experiencing leaks, please ensure that you have followed the fitting instructions carefully. Carry out a quick check after fitting your mask:
•Is the mouth cushion creased? Creases can allow air to leak out of the mask.
•Have you cleaned your mask recently? Oils on the cushion and pillows can affect the seal.
•Are the pillows correctly seated in your nostrils?
•Are your headgear straps overtightened? Try not to alter the upper headgear straps once they have been tightened by your clinician.
•If you cannot establish a comfortable seal, do not overtighten the headgear. Consult your clinician.
•Try another nasal pillow size.
If you cannot resolve any problems, look at the Troubleshooting section, or talk to your clinician.
