I'm new to all this. My Mirage II was OK for one night, now leaks so much. It works for a few hours during the night and then then it won't seal. I'm thinking when my face is damp after I've washed it, the membrane sticks better. Can I put K-Y on my face to get a better seal? Also the humidifier in my Resprionics is so lame that I have to preheat my water or my nose gets cold! Any comments on that? I am getting a Fisher 432 full face - will see how that goes.
