ResMed AirFit™ N20 Nasal CPAP Mask Headgear

The N20 and N20 For Her are nearly identical, except that the N20 For Her model comes in a smaller cushion size, and features lavender colored highlights on the mask headgear as opposed to the standard N20 which is larger and features blue coloring.

The AirFit™ N20 is a nasal mask. Its popularity is primarily based on the fact that based on recent testing, it comfortably fits a remarkable 99% of people in general. This design has been trusted by sleep doctors and CPAP users alike for a number of years now.

First, disassemble your AirFit™ N20 Nasal CPAP Mask. Isolate the frame and headgear from the cushion. Soak the N20 frame and headgear in warm water (approximately 30°C) with mild liquid detergent (like dishwashing liquid) for up to ten minutes.
Please do not use strong chemicals as this can cause the headgear to deteriorate. To ensure a thorough clean, shake the frame and headgear in water. Rinse both components in clean water. Once you have completed this, allow these components to air dry until moisture is no longer present.

Along with technological improvements, users have mentioned that the added swivel and quick disconnect is much more convenient and the nose pillow has a more stable attachment point. People have also reported that exhalation during CPAP therapy is much improved in the N20 over the N10 version.
