The ResMed QuattroFX is the unobtrusive alternative to traditional full face masks. Sporting a headgear and frame design that starts midway on the nasal bridge, the Quattro FX provides patients with a clear line of vision and feeling of openness that helps encourage compliance. Compact, lightweight and quiet, the Quattro FX makes therapy acceptance easier for patients. Recommended replacement annually, with cushion being replaced as needed for proper seal. Wipe down once a day with a damp cloth and wash in warm, soapy water once a week with a gentle soap.Quiet: built-in vents quietly and gently direct exhaled air away from you and your bed partner for a quieter, more relaxing sleeping environment.
Simple: set-it-and-forget-it headgear keeps your settings in place, and is designed to avoid the sensitive area around the back of your neck.
Flexible: the air tube features a 360??rotating connection that easily adjusts when you change position and move in your sleep.
