After you've been diagnosed, your home care provider or doctor will talk to you about choosing the right therapy device and mask for your condition. You can then purchase your mask and device from an equipment supplier (or HME).* Finding the right equipment supplier can make all the difference to your therapy. A good supplier will not only help you set up your equipment, go through the settings on your device and help you find a mask that’s right for you, but they will also be a good source of support throughout your therapy journey.
