Focus on capacity, cooking functions, and the type of convection system. A larger quart size (e.g., 24‑26 qt) lets you handle whole chickens or 12‑inch pizzas, while a compact model saves counter space. Look for dual‑speed fans or super‑convection for faster, more even crisping, and check if the unit includes extra tools like rotisserie spits or dehydration trays.

Premium models often add dual‑zone cooking, more preset programs, and higher‑end finishes such as stainless‑steel French doors, which let you cook two dishes at different temperatures simultaneously. Budget‑friendly units like the Chefman or NutriChef provide solid air‑fry performance but usually have a single cooking zone and fewer accessories. The price gap reflects these added conveniences and build quality rather than a huge difference in basic air‑fry capability.

Dual‑zone ovens let you bake a main dish in one compartment while crisping a side in the other, saving time and avoiding the need for multiple appliances. This is especially handy for families or entertaining when you need different temperatures at once. If you rarely cook multiple items together, a single‑zone model will likely meet your needs at a lower price.

A dual‑speed fan offers both regular and high‑velocity airflow, giving you control over how quickly heat circulates for delicate baking versus rapid crisping. Super‑convection models, like the Breville Smart Oven Air Fryer Pro, push more air through the chamber, reducing cooking time by up to 30 % and producing a more uniform golden crust. For everyday use, the extra speed can make a noticeable difference in texture, especially for fries, chicken wings, and pastries.

Extra functions add versatility: a rotisserie (found on Chefman and some Emeril models) is great for evenly cooked whole birds, while dehydration lets you make jerky or fruit snacks without a separate appliance. Steam infusion, like in the Our Place Wonder Oven, can keep baked goods moist and improve flavor in meats. Choose based on your cooking habits—if you love experimenting with snacks and low‑oil roasting, a model with multiple functions offers better long‑term value.

Higher‑priced units typically include premium materials, larger capacities, dual‑zone technology, and more preset programs, which can streamline cooking and reduce the need for additional gadgets. Mid‑range models often strike a balance, offering solid performance and essential accessories such as rotisserie spits at a more accessible cost. Evaluate whether the extra features will be used regularly; if not, a well‑reviewed mid‑range oven can deliver comparable results for less money.

Look for removable, dishwasher‑safe trays and non‑stick interiors that simplify cleanup, as seen on the Cuisinart and Ninja models. Some ovens include extra accessories like drip trays, baking pans, or glass cooking bowls—make sure they are easy to disassemble and store. Regularly cleaning the fan and heating elements will preserve air‑flow efficiency and extend the appliance’s lifespan.
