CPAP cushions or pillows create a seal between your mask and your face. A good seal is essential to effective therapy, so it's important that you care for your CPAP mask cushions and replace them as needed. Over time, they will lose their elasticity and the quality of the seal will degrade. Silicone cushions should be replaced every 3-6 months, memory foam or gel cushions every 1-3 months, and nasal pillows monthly. Cleaning cushions for CPAP masks to remove oils and bacteria can help extend their lifespan, so we recommend making this part of your weekly routine. You can also wash your face before putting on your mask to reduce potential buildup and skin irritation.
