The CPAP Pro 'No Mask' provides the ultimate in comfort and convenience for CPAP & BiPAP users. The only part of CPAP Pro that touches the face is the super soft nasal pillows that rest gently on the base of the nostrils. CPAP Pro's custom fit mouthpiece keeps the pillows in place and in perfect alignment throughout the night, no matter how much you twist and turn, so can enjoy a brilliant, restful night's sleep.
