Instant Vortex Plus air fryer remembers your settings, which makes it easier for you to prepare your meals with the touch of a button. It also features a unique Dehydrate button. Air frying replaces hot oil with super-heated circulating air to produce the same crunchy taste and texture that makes deep-fried food so good. It uses up to 95% less oil to prepare the healthy version of your favorite fried foods, and a whole lot more.
