Q: QuestionCan this unit be placed and used in the space designed for a microwave oven? Or does it need open air for venting?

Asked 2 months ago by StacieS.

• A:Answer The Prestige Air Fryer requires proper ventilation for safe operation. Ensure the air fryer has at least 4 to 6 inches of clearance on all sides and above to allow proper airflow, and avoid placing it in enclosed cabinets or tight spaces where heat and steam can build up. For best results, always place it on a stable, heat-resistant surface with good air circulation.

Q: QuestionWill it accommodate my 15 inch pizza stone?

Asked 3 months ago by Baker.

• A:Answer Thanks for your question! The Prestige Smart XL is designed to cook up to a 12‑inch pizza, and the interior width is approximately 13.9 inches. Because of this, a 15‑inch pizza stone will not fit inside the oven. We recommend using a 12‑inch pizza stone or pan for proper airflow and best cooking performance.
