The non-stick containers in most air fryers are coated with Teflon, made with "forever chemicals" (PFAS).
I'm sorry.
I upgraded my kitchen to a stainless steel (Breville) toaster oven with an air fryer function, to avoid air fryer appliances / PFAS, and also the oven on my gas stove (carcinogenic benzene).
PFAS are worth avoiding wherever you can to the extent it's possible.
