The Zest™ Q boasts of being the first interface to bring Fisher and Paykel into the spotlight. It comes with an advanced diffuser which allows for better sleep for your partner, by directing air away from him/her. Following on the success of the nasal Zest range, the Zest™ Q rides on the successes of the Flexifit™ 405, Flexifit 406™, and Flexifit 407™ range. If any of the Flexifit were to your liking, you could simply upgrade to the Zest Q.
The Zest Q also features the FlexiFit™ which is a type of cushion that provides the wearer with maximum comfort. Furthermore, the cushion is made out of Flexifoam which can self-adjust on the nose, needing no extra help on your part.
If needing to know the size of what you are using currently for replacement the sizing is located under the elbow and is quite difficult to see.
