Masks
CPAP masks are sold separately, giving you the freedom to choose the one which will best suit your nighttime breathing style and face shape.
Humidifiers
Some machines, like the Sleepstyle, have an integrated humidifier to make your CPAP therapy more comfortable and to reduce condensation in your tube.
Other machines, such as the RedMed Airsense 10 and Löwenstein Medical Prisma SmartPlus, offer an optional humidifier.
