The ResMed AirFit P10 For Her nasal pillows mask comes in an extra small size specifically catering to women with smaller nostrils. The ResMed AirFit P10 For Her nasal pillows mask is the quietest mask yet, delivering the performance and reliability of the popular Swift FX mask series in a design that's approximately 50% quieter and 50% lighter.  Engineered to encourage patient acceptance, the AirFit P10 provides a stable seal, excellent usability and extremely high level of comfort, with a QuietAir vent that gently disperses away expelled air at a barely audible level. A recent clinical study also found that patients received more than 40 minutes of additional sleep per night using the AirFit P10 compared to its predecessor.  It is so comfortable and effective, it won a world-coveted Red Dot Award for excellent product design. The ResMed AirFit P10 Nasal Pillows is designed to be as unobtrusive and comfortable as possible, and features a revolutionary new flexi-tube that's ultra light and highly durable, letting patients move around more freely without compromising seal. The AirFit P10 is also 50% lighter than our leading nasal pillows mask. The ResMed AirFit P10 For Her Nasal Pillows mask comes with three sizes of pillows: extra small, small, and medium.
