Frequently Asked Questions
Do most air fryers have PFAS in them?
Many conventional air fryers use PTFE (a PFAS compound) to coat the basket and drip tray for non-stick performance. Some newer models use ceramic or stainless steel instead. The key component to check is the non-stick coating on the cooking basket — that is where food contact happens at high temperatures.
Why are air fryers a bigger PFAS concern than regular pans?
Air fryers operate at very high temperatures (up to 450 degrees Fahrenheit) with intense circulating air. PTFE coatings begin to degrade and release toxic particles at temperatures above 500 degrees Fahrenheit, and localized hot spots in air fryers can approach those levels. The combination of extreme heat, confined space, and long cook times makes PFAS-coated air fryer baskets a higher-risk exposure than a standard pan on the stovetop.
What should I look for in a PFAS-free air fryer?
Look for air fryers with stainless steel baskets (no coating needed), ceramic-coated baskets (PFAS-free non-stick), or explicitly labeled PFAS-free and PTFE-free models. Avoid any air fryer that only claims to be 'PFOA-free,' as this does not mean it is free of all PFAS compounds.
