The Fisher & Paykel Zest Q range of nasal masks takes the best of Zest and offers an over-the-nose solution that's extremely quiet, fits better, feels lighter, and, as always, is easier to use. Available with or without headgear. One of the unique features is just how quiet it is. The F&P Zest Q minimizes partner disturbance with the Advanced Air Diffuser to ensure a better sleep life. The refined Air Diffuser design ensures minimal noise and efficient exhaust dispersal. Use with the cover for extra quiet, or use without the cover. Incorporating Fisher & Paykel Healthcare's proven variety of features and benefits, the F&P Zest Q Nasal Mask comes in three separate sizes, and is an Out-of-Box solution fully assembled and ready for use.
