Quattro™ FX For Her Full Face CPAP Mask Assembly Kit

The Quattro™ FX For Her Full Face CPAP Mask Assembly Kit works with the Headgear For Quattro FX For Her Full Face CPAP Mask which is streamlined and designed to rest lower on the back of the head allowing for use with a pony tail.

The Quattro FX For Her offers less contact with the face to create a more comfortable fit. This allows for a more natural field of vision and the design works well for side sleepers.

The Quattro FX For Her offers the flexible Spring Air dual wall cushion along with the Swing Seal fitting technique which helps provide a good seal. When the air moves through the cushion the outer layers inflates over the face rather than stretching.

The popular features of the original Quattro are included on the Quattro FX, such as the 360 degree elbow rotation, the set and forget headgear clips and the quiet exhalation vent design.

This product is the mask only and does not include the headgear. The headgear can be purchased separately Headgear For Quattro FX for Her Full Face Mask. Or, purchase the entire mask and headgear Quattro™ FX For Her Full Face Mask with Headgear.

The mask system does not contain latex, PVC or DEHP materials.

Where do I find the size?

The size of the mask frame is located in three separate locations.

1. Turn the mask upside down. The flat bottom of the mask frame and mask cushion needs to face the user. A clear letter embossed between the ports cap and the edge of the mask frame will indicate the size of the mask frame.
2. Turn the mask to face the user. Look below the swivel to identify a blue letter, which represents the size of the mask frame.
3. With the mask facing the user, locate the lower connection points for the headgear. A clear letter is embossed on the top of the connection point, where the headgear clip meets the mask frame.

The size of the full face cushion is located on the flat bottom of the cushion. Turn the mask upside down with the headgear facing away from the user. Located on the bottom silicone flap to the right side of the name of the mask, an embossed clear letter will specify the size of the full face cushion. The letter is larger than the word ResMed and Quattro™ FX.

Quattro and Quattro FX mask frames, cushion clips and cushions are NOT interchangeable. Individual cushions are NOT interchangeable within each mask. The size must correspond for the mask to work properly. For more information visit the Mirage Quattro FX Full Face Mask Cushion and Clip.

Sizing Help
