NEW!! The AirTouch N20 features the ResMed UltraSoft memory foam cushion, a breakthrough in CPAP apparatus comfort technology. This innovative new cushion conforms to the unique contours of each face for a truly personalized fit. It is also designed to deliver a light, breathable seal across a wide range of therapy pressures. Existing users of the N20 can purchase the UltraSoft memory foam cushion to try on their existing apparatus, and users who purchase the AirTouch N20 can purchase the silicone AirFit N20 cushion to try if desired. Due to the nature of the foam, it cannot be washed like a traditional apparatus. The foam can be wiped daily, but the cushion is only intended to last 30 days before needing to be disposed and replaced.
