9Qt 8-in-1 Dual Air Fryer vs Crispi 4-in-1 Portable Glass Air Fryer Cooking System: which is safer?

Where these two actually differ

• We flag PTFE fume risk (nonstick coating degradation), Coating flaking and particle inhalation and Bacterial growth in hard-to-clean dual chamber on the Cosori and not on the Ninja.
• We flag Thermal fracture or stress in glass cooking vessel, Plastic housing off-gassing (VOCs and formaldehyde) and Electrical hazard or heating element degradation on the Ninja and not on the Cosori.
• The Cosori is Nonstick-coated basket and trays; coating type undisclosed where the Ninja is Glass cooking vessel with stainless steel and plastic components, which is most of the difference in these two grades.
• The gap is 60 points, wide enough that this is not a close call, and the Ninja is the one to buy.
• We are less certain about the Cosori grade, at 35% confidence against 75%, because it discloses less.
