Where these two actually differ
- We flag Sealing ring degradation and odor absorption, Stainless steel surface pitting and corrosion, Pressure release valve clogging and Thermal injury from steam or pressure release on the Instant Pot and not on the Presto.
- We flag Nonstick coating identity and degradation risk, PTFE fume inhalation (if PTFE-based) and Coating leaching into acidic or fatty foods on the Presto and not on the Instant Pot.
- The Instant Pot is Stainless steel pot/bowl, no nonstick coating disclosed where the Presto is stainless steel cooking surface, unspecified nonstick interior coating, 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.
Both products run through the same public rubric: 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 →
