Mask assembly kits are a way to refresh your mask without having to purchase the full mask.
About 40 percent of people who use a CPAP machine and just about all BiLevel machine users lose pressure directly from the mouth. This happens usually through leaks from the mouth or via mouth breathing while wearing a nasal mask. The resulting loss in pressure may bring about flu-like characteristics, inadequate sleep therapy, and disrupted sleep. Since the Ultra Mirage full face mask covers both the nose and mouth it prevents pressure loss from mouth breathing thereby improving both your comfort and your sleep therapy.
