I’m asking because recently I switched to a new mask and for some reason I feel worse and groggy with headaches while using it. Though the sleep data shows my apneas are under control. I switched from a full face to another full face mask so its definitely not the mask type that is the issue. The new mask is an air touch f20 by resmed. My cpap is BMC luna g II. So now I’m wondering if some cpap masks can be more efficient then others.
