Is my non-magnetic mask compatible with my existing device and settings? 

Yes, since the only update to the non-magnetic variant is the non-magnetic clip, therapy device used with your AirFit™ F20 or AirFit™ F30i still stays the same. If in doubt our ResMed Sleep Coaches* can help you with fitting.
