Frequently Asked Questions

Most air fryers still use coatings made with PFAS and PTFE, also known as Forever Chemicals. Ours doesn’t. Every food-contact surface in the Wonder Oven Pro is made from safe, high-performing materials like stainless steel and ceramic nonstick coatings. That means no toxic fumes, no hidden chemicals, just healthier cooking.

Simply put, it’s the best of both worlds: crispy air frying plus the everyday versatility of a toaster oven. With a user-friendly digital interface, you set exact temperatures and times for consistent results. Rapid air circulation creates golden, crisp textures with little-to-no oil, while the oven handles everything from roasting veggies to baking cookies to homemade pizza nights.

If you already love your kitchen setup, maybe not. But if you want one compact appliance that can air fry, bake, roast, toast, and more (without heating up your whole kitchen) the Wonder Oven Pro might be the only upgrade you need.

Air frying cuts down on oil while still giving you crisp, golden results. Steam infusion keeps food juicy inside and crisp outside, giving leftovers that fresh-out-of-the-oven feeling. Faster preheats save you time, and digital precision makes it easier to nail recipes on the first try.

Yes. Every Wonder Oven comes with a 100 day risk-free trial. Cook, test, experiment, and if it’s not the right fit, send it back — no hard feelings.

Both are multifunctional countertop air fryer toaster ovens with steam infusion technology. The Pro has a larger 30 L interior (vs. the standard-sized 12 L), a digital control panel for exact time and temperature settings, and eight cooking modes instead of six. You also get 3 cooking tiers (vs. 2), two wire racks, and a deeper bake pan to catch grease. Both are non-toxic, compact, powerful, and come in a range of stylish shades.

Can’t decide? Here’s a quick and easy breakdown:

Cooking for two? The standard-sized Wonder Oven — the classic — will fit the bill.
Cooking for a family? The Large Wonder Oven is probably more your speed.
Prioritize precision for more involved recipes? The Wonder Oven Pro is what you need.
