Where these two actually differ
- We flag Stainless steel corrosion and metal leaching, Silicone gasket degradation and off-gassing and Bacterial growth in water reservoir or seal cavities on the Instant Pot and not on the Tiger.
- We flag PTFE fume inhalation (nonstick coating), Coating degradation and microparticle release, Aluminum leaching from bowl interior and Unidentified PFAS in coating formulation on the Tiger and not on the Instant Pot.
- The Instant Pot is Stainless steel pot with no nonstick coating where the Tiger is Inner cooking bowl with nonstick coating (type unspecified); aluminum/steel body, 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 Instant Pot is the one to buy.
- We are less certain about the Tiger grade, at 45% confidence against 82%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
