Air fryers are made from plastic materials with a metal basket. Some higher-end air fryers are made with stainless steel materials. While stainless steel air fryers last longer than plastic air fryers, they are more prone to scratches.
It's important to consider the best material when selecting an air fryer because it affects food taste, safety, and durability. Metal is the most common material for an air fryer basket because it heats well and won't melt. The material you choose also affects the price. Higher-end materials, like stainless steel, cost more than plastic materials. On average stainless steel air fryers can be 30% more expensive than plastic air fryers.
Some have concerns over plastic air fryers, especially if the plastic contains chemicals. These chemicals may peel with high heat which can be dangerous. If you're concerned with these potential health risks, it may be a good idea to go with a higher-quality unit made with metal or stainless steel materials.
