Premier Hard-Anodized Nonstick Frying Pan Set vs Rio Ceramic Nonstick Frypan: which is safer?

Where these two actually differ

• We flag PTFE fume risk (if coating contains fluoropolymers), Coating degradation and particle shedding and Brand transparency and consumer recourse on the Calphalon and not on the GreenPan.
• We flag Ceramic coating degradation and peeling, Aluminum leaching from base metal and Coating adhesion loss and metal exposure on the GreenPan and not on the Calphalon.
• The Calphalon is Hard-anodized aluminum with nonstick coating (type unspecified) where the GreenPan is ceramic nonstick coating, which is most of the difference in these two grades.
• The gap is 75 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
• We are less certain about the Calphalon grade, at 35% confidence against 82%, because it discloses less.
