Micro 510 CPAP Machine with Vitera Full Face Mask BundleThis bundle is for people who breathe through their mouth during sleep, deal with nasal congestion, or have tried nasal masks before and kept waking up with leaks. The F&P Vitera covers both nose and mouth. The RollFit XT cushion moves with your face as you shift positions during the night, which helps it hold a seal without needing to be strapped on tightly. That also means less pressure on the bridge of your nose compared to most full face masks.
