Instant Pot Stainless Steel Inner Pot vs. De Buyer Mineral B Carbon Steel Pan

Materials

• 18/8 stainless steel interior
• No non-stick coating

Common claims

• Food-grade stainless steel
• Multi-function cooker
• No PTFE coating

Concerns / watch-outs

• Some models offer non-stick inner pots as accessories — avoid those and stick with the stainless insert
• Gasket/seals are silicone; replace per manufacturer schedule

Notes

The standard stainless insert is one of the cleanest cooking vessel options. Avoid the optional non-stick insert accessories if PFAS avoidance is a priority.

Cleaner alternatives

• stainless steel
• enameled cast iron

Materials

• 99% carbon steel
• Natural beeswax finish

Common claims

• Made in France
• Professional grade
• PTFE and PFAS-free

Concerns / watch-outs

• Requires seasoning before first use; reactive to acidic foods until well-seasoned
• Heavier than standard carbon steel pans

Notes

De Buyer Mineral B is widely regarded as one of the best carbon steel pans available. The beeswax protective coating burns off during seasoning leaving pure seasoned carbon steel — completely coating-free in use.
