What Is the Instant Pot Omni Plus Interior Made Of?
The Instant Pot Omni Plus 18L features a stainless steel interior rather than a traditional non-stick coated basket.
Unlike PTFE-based coatings, stainless steel does not rely on fluoropolymer compounds to create a non-stick surface. Instead, it uses raw metal construction designed for durability and high-heat resistance.
This makes it appealing to buyers who want to completely avoid non-stick coatings in their cooking chamber.
Does Instant Pot Omni Plus Contain PTFE or PFAS?
The cooking interior itself is stainless steel and does not use traditional PTFE-based non-stick coating.
However:
• External housing still contains plastic
• Heating elements are metallic
• Electrical components are standard appliance materials
The key difference is that food-contact surfaces do not rely on Teflon-style coatings.
For buyers seeking zero coating contact with food, this is a significant advantage.
Is Stainless Steel Safer Than Ceramic?
Stainless steel offers several advantages:
✔ No non-stick coating to flake
✔ Extremely durable under high heat
✔ Long lifespan with proper care
However, stainless steel is not naturally non-stick.
You may need:
• Light oil for certain foods
• Slightly more cleaning effort
• Proper preheating technique
Compared to ceramic-coated baskets, stainless steel prioritizes durability over convenience.

Real-World Safety Considerations
Users commonly report:
• No chemical smell during first use
• Strong build quality
• Even heating across multiple cooking modes
Because it functions more like a countertop oven, airflow and heat circulation may differ from basket-style air fryers.
If properly maintained, stainless steel interiors can last significantly longer than coated baskets.
Who Should Buy the Instant Pot Omni Plus?
This model is ideal for:
✔ Buyers avoiding all traditional non-stick coatings
✔ Families needing larger 18L capacity
✔ Users wanting oven-style versatility
✔ Long-term durability over convenience
Who Should Avoid It?
This may not be ideal if:
✖ You prefer compact basket-style air fryers
✖ You want ultra-lightweight design
✖ You prioritize easy non-stick cleanup

Final Verdict: Is Instant Pot Omni Plus PFAS-Free?
The stainless steel interior of the Instant Pot Omni Plus avoids traditional PTFE-based non-stick coatings.
While no appliance is entirely free of synthetic materials, the food-contact cooking chamber itself does not rely on fluoropolymer coatings.
For buyers prioritizing durability and minimal coating exposure, it remains one of the strongest stainless steel alternatives available in 2026.
