You want the most powerful glass air fryer available -- 1800W is best-in-class.
You need 450F max temperature for high-heat cooking like searing.
You accept nano-ceramic crisper plates and the glass container design tradeoff.
The 6-in-1 functionality with two container sizes adds versatility for your kitchen.
You are noise-sensitive -- 72 dB is the loudest air fryer tested, louder than a normal conversation.
The 300-dollar price point seems high when the cheaper Crispi 4-in-1 has the same safety profile at 180 dollars.
You want zero coating risk -- nano-ceramic has limited transparency per Sustainably Kind Living.
You require independently verified PFAS-free testing or UL/ETL certification.

“Are the materials my food touches actually safe, and has anyone independently verified that?”
The full reasoning is in the verdict above.

Criteria
Aluminum without food-grade qualifier — unconfirmed whether anodized, treated, or raw. Raw aluminum can leach into acidic foods. Score 4 reflects disclosed material without food-grade certification.
nano-ceramic: engineered nano-scale particles (1–100nm) have documented enhanced penetration risk under abrasion vs standard ceramic — SKL explicitly rejected Ninja Crispi for 'nano-ceramic with limited transparency'. proprietary-not-disclosed: 'nonstick' without coating name — cannot assess PFAS/PTFE content. Both score 1 per opacity principle.
“Will this air fryer actually crisp food well and heat up fast enough for weeknight cooking?”

Criteria
Serious Eats 34-model test: square baskets 'consistently outperform round for crisping quality' — more surface area, better airflow. Glass-bowl-convection-rack provides 360° airflow. Both represent optimal cooking geometry.
“How easy is this to clean, how loud is it, and will it last?”

Safety standards and ingredients related to Ninja Crispi Pro 6-in-1 Glass Air Fryer
A low-temperature setting (typically 95-170F) on select air fryers that slowly removes moisture from food to create dried snacks like fruit chips, beef jerky, dried herbs, and yogurt drops. The dehydrator function lets families make preservative-free snacks at home with no added sugar or artificial ingredients.
A rotating spit or tumbling basket feature found primarily in oven-style air fryers that slowly turns food for even browning on all sides. The rotisserie function combines slow rotation with convection heating to cook whole chickens, roasts, and larger items with consistent results in one appliance.

All confirmed food-grade material families: borosilicate glass (chemically inert, heat-resistant), 304/316/18-8/18-10 stainless (FDA 21 CFR compliant, non-reactive, corrosion-resistant). Explicit grade confirmation required to score 10 — 'stainless' alone maps to score 8. Both families recommended by primary sources as safest available.
Brand self-reports PFAS-free or PTFE-free without naming a certifying body or publishing a test report. SKL: 'PFAS-free does not guarantee a product is completely non-toxic.' No evidentiary weight, but positive claim is better than silence.
Fastest preheat, strongest temperature maintenance. Tom's Guide top pick (Ninja Pro) at 1750W rated 'supremely powerful'.
Loud — Ninja Pro at 72 dB (loudest in Tom's Guide testing).
1 year: baseline industry standard.
