My mask seems to leak alot, how can I fix this?

Many issues can cause a mask to leak.  Over tightening, improper size or not replacing the cushion is all reasons a mask can leak.  In order to get the best seal, put your mask on while the CPAP is ON and set to the lowest pressure by using Ramp.  If you experience leaks during the night, pull the mask away from your nose and put it back on.  This inflates the mask again and allows the cushion to form a new seal around your nose.  Full Face masks are for patients who are NOT able to breathe through their nose at night due to congestion or other nasal issues.  Mouth breathing will happen to everyone, no matter what mask you use and is controlled by a chin strap.  Full Face masks will be the toughest mask to get a seal.
