Airfit F20 foam

Last night was a game changer for me. On the F20 without the foam I always had a mark left on the side of my nose. I resorted to using a Bandaid which leaked at times but still left a mark on my nose. Last night was the first night with the new foam mask. This morning it left no mark whatsoever. I will post long term usage of this mask but so far it gets an A+ from me.
