Typhur Typhur Dome 2 Air Fryer earns R3's top pick at 8.2/10
After scoring both air fryers across our V4.2 rubric, I'm giving the edge to Typhur by 0.5 points. The Typhur's ceramic nonstick basket earned a 7.1 safety score in our V4.2 rubric, where safety carries 50% of the overall weight. At $499 vs $100, the premium reflects stronger safety and performance scores. That said, the Granitestone's borosilicate glass basket still meets our safety baseline - so if Granitestone's price or features fit your routine better, it's not a bad choice.

Why 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. Granitestone's borosilicate glass basket scored 9.2/10 here.

The Granitestone Big Boss 16Qt Large Glass Air Fryer uses a borosilicate glass basket with a stainless steel crisper plate. Stainless steel and glass are inherently PFAS-free materials, so this model passes our material safety screen.
Between these two, the Granitestone Big Boss 16Qt Large Glass Air Fryer (borosilicate glass basket, 9.2/10 safety) uses materials I'm more comfortable with at high heat. The Typhur Dome 2 Air Fryer's ceramic nonstick basket scored 7.1/10. 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: Granitestone offers 16-qt vs Typhur's 5.6-qt. For cleanup, both are dishwasher-safe. Overall, I'd lean toward Typhur 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.
