Where these two actually differ
- We flag PTFE coating degradation and fume inhalation, Coating peeling and microparticle ingestion and PFAS exposure from nonstick manufacturing and use on the Calphalon and not on the Our Place.
- We flag Iron leaching from bare metal surface and Rust formation from improper storage or care on the Our Place and not on the Calphalon.
- The Calphalon is Hard-anodized aluminum with PTFE-based nonstick coating where the Our Place is carbon steel (bare metal, no coating), which is most of the difference in these two grades.
- The gap is 95 points, wide enough that this is not a close call, and the Our Place 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 →
