2. Check and Remove Food Residue
Food particles, grease, or oil splatters can cause smoke when heated. Ensure no debris is stuck on the heating element or in the basket. Use a soft brush or cloth to clean hard-to-reach spots.
3. Use Proper Liners and Placement
- Use recommended liners like the Cosori Air Fryer Liners or Air Fryer Paper Liners, but never during preheating or without food on top.
- Place liners carefully to prevent them from flying up and touching the heating element.
- Avoid overfilling the basket, allowing hot air to circulate freely.
4. Adjust Cooking Temperature and Time
High temperatures (close to 450°F) can cause smoking, especially if food or grease is present. Lower the temperature slightly and monitor the process. Use the controls or your smartphone app to make precise adjustments.
5. Prevent Grease and Oil Buildup
Regularly check for and remove excess grease or oil that can accumulate during cooking. Proper cleaning and avoiding excess oil can significantly reduce smoke production.
