Drift off to a great night's sleep with the ResMed Quattro Air full face mask. The ResMed Air - Fit F20 'For Her' full face mask is the female version of the Air - Fit F20. Designed specifically to give women a more personalised mask that better suits her unique facial features and adapts to the way she sleeps. Made up of just four parts, it is easy to use, clean and assemble. The dual wall Spring - Air cushion reduces pressure on the face while maintaining a high-performance seal, designed to deliver supreme comfort for your sleep apnea therapy and the Quiet - Air diffuser vent, gently expels air away from the wearer, making it one of Res - Med's quietest full face masks.
