The mask is a great idea but unfortunately, using the liner distorted the shape of the membrane that creates a seal on the face. The result was a unacceptably high level of air leakage even at relatively low levels of air pressure. It may work more effectively with other mask designs but not for AirFit F20 size M. YMMV.
