Severe facial air leakage at pressure of 14+.
Love everything about design except it leaks like crazy on my face at my pressure of 14.8. It leaks at my cheeks on both side making a loud fluttering noise. Tried medium first, but leaked bad. Then switched to large and leaked less, but still a lot of leakage. Tried over-tightening mask in both cases and it helped, but problem still was there. Just the slightest head movement or open mouth action would start the fluttering leak. Very noisy. The mask is very comfortable and I wish I would have had success with it. I use an F30 and would prefer a better fit than it gives me, but I live with it.
