Preheating is not always required, but it may help improve the cooking consistency for certain foods by ensuring even heating from the start. Some air fryers include a preheat function, while in other cases, you can run the air fryer for a few minutes to allow it to preheat.

Air fryers can be used to prepare a wide variety of foods, including vegetables, meats, seafood, frozen foods, and snacks. They are commonly used for dishes such as fries, chicken, and roasted vegetables. You can also explore different recipes to make the most of your air fryer.

The air fryer baskets and crisper plates can be cleaned with warm water, mild soap, and a non-abrasive sponge. We recommend cleaning the basket after each use to remove food residue and grease. The exterior and heating elements can be wiped down as needed. We recommend allowing the appliance to cool completely before cleaning. For detailed cleaning instructions, refer to your air fryer's user manual or our blog.

Foods with excessive batter, very wet mixtures, or lightweight leafy greens may not cook well in an air fryer. Additionally, certain items may require adjustments to prevent burning or uneven cooking. Follow recommended air fryer cooking guidelines to help achieve better results.

Yes, aluminum foil can be used in an air fryer, but it should be done so carefully. The foil should not block airflow or cover the entire basket, as proper air circulation is important for cooking performance. We recommend keeping the foil secured and avoid placing it too close to the heating elements.

Always follow the guidelines in your user manual for safe use. For best results, use aluminum foil only when appropriate for the recipe and ensure that food is placed securely on top.
