BetterWhy it matters: For air fryers, basket material is the single biggest factor in our safety scoring - it accounts for 60% of the safety pillar, which itself carries 50% of the overall V4.2 score. We evaluate whether baskets use PTFE coatings, stainless steel, borosilicate glass, or ceramic, and check for Prop 65 warnings and third-party PFAS testing. Ninja's undisclosed material basket scored 9.8/10 here.

The Instant Vortex Plus 6-Quart Air Fryer uses a undisclosed material basket. PTFE-coated nonstick may contain trace PFAS compounds, which is reflected in its 6.5/10 safety score in our V4.2 rubric. For a PFAS-free alternative, look for models with stainless steel or borosilicate glass baskets.
Between these two, the Ninja Crispi Pro 6-in-1 Glass Air Fryer AS101CY (undisclosed material basket, 9.8/10 safety) uses materials I'm more comfortable with at high heat. The Instant Vortex Plus 6-Quart Air Fryer's undisclosed material basket scored 6.5/10. In our V4.2 rubric, basket material accounts for a significant portion of the safety pillar, which carries 50% of the overall score.
For families, capacity comes first: check the capacity specs for your family size. Overall, I'd lean toward Ninja for most families.
304 stainless steel is inherently PFAS-free and won't off-gas at any cooking temperature. Nonstick coatings (PTFE/Teflon) are stable below 400°F but can begin degrading above that threshold. In our V4.2 rubric, stainless and borosilicate glass baskets consistently score higher on the safety pillar. That said, a well-maintained nonstick basket from a reputable brand still meets safety baselines - it's a question of margin, not danger.
We use our V4.2 deterministic rubric with four weighted pillars: Safety (50%), Efficacy (20%), Usability (20%), and Value (10%). For air fryers, safety evaluates basket material composition, Prop 65 compliance, third-party certifications, and PFAS testing. Efficacy covers cooking performance, temperature accuracy, and capacity-to-wattage ratio. Usability scores noise levels, cleanup ease, and warranty terms. Every score is reproducible - the same product data produces the same score.
