Why is air escaping from my mask cushion/pillows?

Over time, mask cushions break down, which will cause air to leak around your mask. This is because, once a mask begins to deteriorate, it causes breaks in the seal. These leaks compromise your therapy and can also make your mask noisy. To stop this from occurring, you may need to change your cushion and/or your pillow. These should be replaced every month.
