De'Longhi Livenza Air Fry Convection Oven vs Crispi 4-in-1 Portable Glass Air Fryer Cooking System: which is safer?

Where these two actually differ

• We flag PTFE (Teflon) fume release under thermal stress, Coating degradation and microparticle ingestion and Bacterial or mold growth in heating chamber on the Delonghi 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 Delonghi.
• The Delonghi is Stainless steel housing; interior cooking surfaces unspecified (likely non-stick or ceramic-coated) 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 Delonghi grade, at 35% confidence against 75%, because it discloses less.
