What is the extra rectangular liner for?
That’s a RemZzzs forehead pad liner. If your mask has a forehead cushion, follow the fitting instructions for how to use appropriately. If your mask does not have a forehead cushion you probably won’t need to use it. Each Month-Supply pack with 30 RemZzzs liners includes (2) forehead liners. Since the forehead liner does not stretch to custom fit your face, it can be used for fifteen days each. You may use all sides of the forehead liner by simply turning it over or refolding.
