Anything special I should do before putting the mask on?
Before wearing your mask, wash your face to remove excess facial oils. This will
allow a better fit and prolong the life of the mask cushion.
Do not use moisturiser when wearing a mask.
My mouth feels dry during treatment—what can I do?
You may experience dryness of the nose, mouth, and/or throat during the course
of treatment, especially during winter. In many cases, a humidifier may resolve
this discomfort. Contact your clinician for advice.
My nose is irritated during treatment—what can I do?
You may experience sneezing and/or a runny or blocked nose during the first few
weeks of treatment. In many cases, nasal irritation can be resolved with a
humidifier. Consult your clinician or equipment supplier for advice.
