It sounds like you're using the Resmed P10 nasal pillow. I've tried that before and agree the mesh vents get clogged easily (not just because of condensation, but also because it gets dirty easily). There are other similar pillow masks out there that don't have that problem. I found the Philips Nuance, Philips Dreamwear, and F&P Brevida to not have any venting issues. The Brevida has a cloth mesh that still works when wet, and probably is the best if you want that "resistance" feeling on exhale.
