Why does my P30i mask feel too tight or too loose?Updated 2 months ago

An improper fit can make the mask feel uncomfortable or unstable during the night. If your mask feels too tight, loosen the headgear straps slightly to relieve pressure on your nostrils. On the other hand, if it feels too loose and shifts around at night, try tightening the straps just enough to maintain a secure fit without excessive pressure.

Another factor to consider is the frame size—ResMed offers the P30i in Small and Standard frame sizes, and using the incorrect one can affect how the mask fits. If you tend to move a lot while sleeping, you might also benefit from using a CPAP pillow, which helps keep the mask in place and reduces pressure points.
