Same here. I use the Honeywell Saf-T-Fit masks, with the exhaust, either N99 or P100. They have a soft cushion where it touches the face and I find it's far superior in comfort on long flights to masks without the soft inner part. A little more expensive, but I'll never fly with a regular N95 again.
