I have a switft FX. My big concern is I hear (and feel) alot of air coming out of the bottom of vent. It sounds like a leak but both masks have this. I feel around my nose and there is no air leakage ...its only coming from the vent.

I just got a PR Series 1 on a rental and its very noisy too.

My wife has a ResMed and you can't hear it ...it almost like the noise it coming out of the exhale port as I don't feel any leaks around my nose.
