Instant Pot Stainless Steel Inner Pot vs. Unglazed Clay Cooking Pot

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

• Natural clay
• Unglazed interior

Common claims

• Traditional cookware
• Chemical-free
• Mineral-rich cooking

Concerns / watch-outs

• Glazed clay pots may contain lead or cadmium in older or imported pieces — verify lead-free glazes
• Requires soaking before first use; thermal shock can crack the pot

Notes

Unglazed clay is extremely inert and imparts no harmful compounds. For glazed versions, verify the glaze is lead-free before purchase.
