I think it is smaller capacity, has a "fryer basket" and maybe hence can concentrate the power more effectively on the small space so is faster? IDK, the NuWave used to be sold as an air-fryer too, but I've never air-fried in a "real one" so I can't personally compare. I just find that the much larger "Oven" and throw everything in the dishwasher is way more useful for way more foods and types of cooking (like if I want to bake a potato etc).
