2. Remove and Inspect the Basket
- Take out the fryer basket and inspect it for grease, food debris, or residue that might be causing smoke.
- Check the heating element at the top for any buildup or splatters.
3. Clean Thoroughly
- Wash the basket, tray, and any removable parts with warm, soapy water. Use a non-abrasive sponge to remove grease or food particles.
- Clean the heating element gently with a soft cloth or brush if needed, being careful not to damage it.
4. Check Food and Liners
If you’re using liners, ensure they are placed correctly and not touching the heating element. Never place liners during preheating or without enough food on top to prevent them from flying up and causing smoke.
5. Use Proper Liners and Cooking Techniques
- Consider using disposable liners like the Cosori Air Fryer Liners or the Air Fryer Paper Liners to catch excess grease and crumbs.
- Avoid overcrowding the basket, which can cause uneven cooking and excess smoke.

Frequently Asked Questions
Why is my COSORI air fryer smoking even after cleaning?
Residual grease or food debris on the heating element or basket can cause smoking. Ensure thorough cleaning and check for food splatters near the heating element.
Can I use liners to prevent smoking?
Yes, disposable liners or silicone mats can catch drips and crumbs, reducing grease contact with the basket and heating element, thus lowering smoke risk.
Is preheating with an empty basket safe?
No, preheating with nothing inside can cause grease or food residue to burn and produce smoke. Always preheat with food or liners in place.
What should I do if my air fryer continues to smoke after cleaning?
Inspect the heating element for damage, check for trapped grease or food debris, and consider replacing or deep cleaning. If issues persist, contact customer support.
