The Ninja CRISPi DualZone Glass Air Fryer is the first glass air fryer with DualZone Technology—cook 2 foods, 2 ways, and finish at the same time. Two independent 4-qt CleanCrisp DualZone Glassware Containers (8-qt total capacity) are designed for nontoxic cooking and storing with no PFAS or PTFE and thermal-shock-resistant glass that goes from fridge to fryer in minutes. Smart Finish staggers start times so two dishes with different cook times finish at the same time, while Match Cook mirrors Zone 1 settings onto Zone 2 for full-capacity double-batch cooking. With 6 customizable functions—Air Fry, Bake, Dehydrate, Max Crisp, Roast, and Recrisp—plus heat-safe handles and counter-safe feet, this nontoxic glass system is designed for use on granite, laminate, marble, and butcher block countertops.
