Where these two actually differ
- We flag PTFE thermal decomposition and fume emission and Coating degradation and microplastic/particle inhalation on the Instant Pot 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 Instant Pot.
- The Instant Pot is Nonstick air fryer basket coating, composition unspecified by brand 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 Instant Pot grade, at 35% confidence against 75%, because it discloses less.
