The Philips Respironics Dreamwisp Cushion for the DreamWisp CPAP Mask includes a nasal cushion in your desired size: petite, small, medium, large, and extra-large. The cushions are designed to fit almost any facial size and structure. The DreamWisp CPAP Mask Nasal Cushion is engineered to help minimize leaks and provide an open field of vision so you can maintain your nighttime routine-like reading a book before falling asleep. This replacement nasal cushion is intended to fit only the DreamWisp Nasal Mask and will not work with any other mask, including the DreamWear or Wisp masks. Over time, your original CPAP mask cushion will begin to lose its ability to create a quality seal. By cleaning your cushion daily, you can prolong the life of the cushion versus replacing every 3 to 6 months. How often should I replace my DreamWisp Cushion? When it comes to replacing your DreamWisp cushion, advice online varies from “every two weeks” to “every six months.” On average, nasal CPAP mask cushions should be replaced every 1-3 months. If your DreamWisp cushion begins to show signs of aging, like cracks, tears, or warping or starts leaking excessively no matter how you adjust it or tighten your headgear, it’s probably a good idea to replace the cushion. General Tips Section Warnings Do not use household cleaners such as sprays or bleach to clean the mask, as this can cause your therapy air to become polluted and leave a residue. The residue can make you very sick. Do not boil the cushion, as this can weaken or damage the materials used in the mask or cause damage or loss of the product.
