Instant Pot Omni Plus vs Breville Smart Oven: Which Is PFAS-Free?

The Instant Pot Omni Plus vs Breville Smart Oven comparison is one of the most relevant matchups for families looking for a non-toxic oven-style air fryer in 2026. Both are countertop oven units with air fry capability, both are popular, and both claim non-toxic credentials — but the interior materials and coating specifics differ in ways that matter for PFAS-conscious households. Here’s the complete breakdown.

Instant Pot Omni Plus vs Breville Smart Oven: Key Differences

Are Both Actually PFAS-Free?

Both the Instant Pot Omni Plus and Breville Smart Oven use stainless steel interiors with stainless steel racks — no coating on the cooking chamber walls or primary cooking surfaces. This means neither unit has PFAS, PTFE, or PFOA concerns in the food contact zone, which is the critical standard for non-toxic oven-style cooking.

The distinction worth noting: some Breville models include a nonstick-coated drip tray. This tray sits below the rack and catches grease — it’s not a direct food contact surface during normal cooking, but it does mean a nonstick element exists in the unit. For the most PFAS-conscious households, replacing the drip tray with an unlined stainless alternative or a foil-covered tray is worth considering. The Instant Pot Omni Plus uses a stainless drip tray throughout. Our full breakdown on PFAS-free air fryer materials explains why every component in the cooking chain matters.

A stainless steel interior with stainless rack — no coating anywhere in the cooking chamber is the standard both units aim for.

Instant Pot Omni Plus: Where It Wins

Better Value for Non-Toxic Family Cooking

The Instant Pot Omni Plus 18L delivers stainless steel interior performance at a mid-range price point that the Breville lineup can’t match. For families who want a PFAS-free oven-style air fryer without a premium price tag, the Omni Plus is the most practical entry point.

More Cooking Functions for the Price

At 11 cooking functions — air fry, roast, bake, broil, toast, dehydrate, reheat, rotisserie, slow cook, proof, and steam — the Omni Plus covers every cooking method a family needs in a single unit. The function range at its price point is hard to match.

Fully Stainless Throughout

The Omni Plus uses stainless steel on interior walls, racks, and drip tray — no nonstick coating anywhere in the unit. For households where eliminating every nonstick element is the priority, this matters.

Breville Smart Oven: Where It Wins

Superior Build Quality and Precision

Breville’s engineering quality is a step above the Instant Pot in terms of build materials, temperature precision, and consistency. For serious home cooks who want precise temperature control and even heat distribution across the full cooking chamber, Breville consistently outperforms in this area.

Better Browning and Crisping Performance

The Breville Smart Oven’s heating element placement and convection system produce more even browning than the Omni Plus — particularly noticeable for baked goods, roasted proteins, and anything where consistent surface color matters. For air frying specifically, the Breville’s results are slightly more consistent across the full rack.

More Durable Long-Term

Breville units are built to last longer than the Instant Pot Omni Plus in typical household use. For a household that wants to buy once and use for 5–7 years without issues, the Breville’s premium build quality justifies the higher price over the long term.

Both units use stainless steel racks — the cooking performance differences show up in heat distribution and precision rather than material safety.

Which Is Better for Non-Toxic Family Cooking?

For most families prioritizing non-toxic cooking on a practical budget, the Instant Pot Omni Plus is the stronger recommendation. It delivers a fully stainless interior, broad function range, and family-friendly capacity at a price that makes the upgrade from a nonstick basket fryer accessible rather than prohibitive.

For households willing to invest in premium performance — and who cook seriously enough to notice the difference in heat precision and build quality — the Breville Smart Oven is worth the premium. Just verify the specific model’s drip tray material and replace if nonstick-coated for a fully PFAS-free setup.
