Designed for mouth breathers and those with chronic nasal congestion, oral CPAP masks deliver pressure solely through the mouth. At CPAP Supply USA, we carry unique oral CPAP masks with optional headgear to facilitate your sleep apnea therapy and treatment. Though different from the traditional full face mask, a CPAP mouth mask functions as effectively as other types of CPAP masks, and its unique lightweight structure gives sleep apnea patients freedom of vision and movement. To determine if our oral CPAP masks are right for you, be sure to consult a medical professional. When purchasing from us, you can help verify your prescription either by submitting your physician's contact information or sending in your prescription via fax or email.
