Answer
Excessive condensation in your mask or air tubing may occur when the room
temperature is low. To prevent condensation, turn the control dial down to a
lower setting. You may need to adjust your humidity setting from season to
season. The use of a ResMed Tubing Wrap can help reduce the effects of
condensation.
Using distilled water will maximise the life of the water chamber and reduce
mineral deposits.
If you have symptoms of dryness, then your humidity setting may be set too
low to be effective. Turn the humidity control dial up.
If you are still experiencing symptoms of dryness, you may be breathing
through your mouth. Mouth breathing or mouth leaks cause drying and
irritation of the upper airway. If this is a problem, a full face mask or chin strap
may help. Consult your clinician or equipment supplier for details.
