A: Yes, the interior walls of the Ninja Double Stack are stainless steel, and the interior, food‑contact components are made with materials considered food‑grade.

A: Great question! For the Ninja Double Stack Air Fryer, some accessories are coated while others are not. The crisper plates are made from non‑stick aluminum and feature a nano ceramic coating, which helps prevent food from sticking and makes cleanup easier. Any included baskets or roasting pans use the same ceramic nonstick surface. The wire racks, by contrast, are made of stainless steel and are completely uncoated. All of the coated accessories are designed for everyday cooking and are PFAS‑free, including being PTFE‑free and PFOA‑free, so you can cook with confidence knowing that traditional nonstick chemicals are not used.

A: The Ninja Prestige Smart XL doesn't have a specific "numerical grade" assigned to it in a standard industry format. Its an 1800-watt electrical appliance, and all of its food-contact components qualify as food grade.

A: You can use parchment paper, aluminum foil, reusable silicone mats, or disposable oven liners in the Ninja Double Stack XL Countertop Oven to reduce cleaning time.

Always place the unit on a heat-resistant surface, keep flammable items away, and allow 15–30 minutes for cooling. Use oven mitts or heatproof gloves when handling the door or trays, and ensure proper ventilation by leaving a few inches of space around the oven to prevent overheating.
