Because the cushions active cell does all the work, the mask is less dependant on headgear tension to achieve and maintain an effective seal. Mirage Activa LT works best with some slack in the headgear-no more overtightening straps! That means quicker fitting time, less callbacks and improved user compliance.
The Mirage Activa LT cushion is not your average cushion. Once therapy is switched on, the cushion is drawn to the face, creating a suction effect-gently, yet securely, creating an unwavering seal. As users move or their therapy pressure changes throughout the night, the cushions active cell automatically expands and contracts, delivering the most effective, comfortable seal.
