I recommend getting one that doesn’t have a pfas/teflon coating on the basket. There are some with glass bottoms, but they don’t look as convenient as the drawer/basket type. Some drawer models have ceramic coatings.
Also, a convection toaster oven can work as an air fryer. These usually have an “air fryer” setting. Probably not as convenient as the drawer/basket models, but they have the advantage of being multipurpose.
Hope this is helpful.
