I'm currently in my ninth mask, and all have leaked just as bad. The problem is not the mask, it's that I'm all over the bed all night long - too much movement. Every time I roll from one side to the other (every 15-20 minutes) the mask dislodges.
I had a big problem with the silicone material. I rolled it between my hands into a thin rope, then tried to place it on the mask cushion (Wisp nasal mask). The silicone just fell off the cushion. It is not sticky, and the cushion is not flat, so there is no way to get it to stay on the cushion as I place it over my nose. Bear in mind that the part of the cushion that is in contact with the skin is just a very thin film so that it will conform to the shape of the face when pressurized. If it was hard plastic I could have stuck the silicone onto it, but the flimsy flap makes it impossible.
Finally, I leaned my head back and placed the silicone around my nose, flattening it down a bit. It still did not stick, but at least it stayed in place long enough to put the mask on. But when I took the mask off this morning the silicone had disappeared. I finally found it on the floor next to the bed.
I bought Mack's ear plugs from a local Walgreen's pharmacy.
For those of you who use silicone ear plug material as a mask sealant, can you give me suggestions for getting it to stay on?
