Cushion/Pillows - Cushion/Pillows are the parts that touch your skin and create a seal for your CPAP or Bi-Level Therapy. These can typically be replaced monthly.
Mask Frame - Mask frame is typically the less-flexible plastic portion of the interface that the cushion fits into. New technology has changed the way that many mask frames look recently – but believe it or not, each and every CPAP interface does have a mask frame. Typically, you can replace your mask frame every 3 months.
