Ultra Quiet: The Mirage Quattro has built-in vents which disperse air gently and quietly so you and your partner can enjoy a good night's sleep. This improved vent design reduces noise by over 50%. The Mirage Quattro's range of set-and-forget options mean that the mask can be precisely adjusted (even while its being worn) to create a perfect fit that stays perfect every time you take off the mask and put it back on.
One Handed Adjustment: There’s no need to take off your mask to use the MicroFit dial. You can simply adjust the dial with one hand while wearing the mask, and even while lying down!
