Well, it depends on the model. But most of the models of Crux Air Fryers have been noticed to be BPA-free. Since the aim of air fryers is to cook food in the healthiest and most nutritious form, they mostly have BPA-free construction because the BPA chemical is the main chemical that disturbs hormones in the human body. Consider the model and check for the construction and composition details before judging whether your Air Fryer is BPA-free or not.
