What Ninja says and does about PFAS
For Ninja, the answer depends on what you bought and when. SharkNinja’s own California disclosure list shows PTFE as the nonstick coating on Ninja air fryers made before 15 August 2024, while the air fryers listed for units made after that date, or bought after 1 January 2025, show aluminum and no PTFE. Its NeverStick Premium cookware lists PTFE, FEP and PFA, while its Ceramic Pro and Extended Life Ceramic cookware list aluminum and stainless steel with no PTFE.
