Why does my mask leak in front?

myAir

When you breathe out, you exhale carbon dioxide, which must be removed so that you don't rebreathe air. Your mask has a vent that releases the exhaled air, which you might feel as a light flow of air.

Airflow may also be caused by a mask leak from the top, bottom or sides of the mask. If your mask is leaking, try following the tips in the mask fit video in your Library or ask your physician or equipment provider for assistance.
