Clean the Air Fryer Thoroughly
Use warm, soapy water and a non-abrasive sponge to clean the basket, tray, and inside surfaces. For stubborn grease, soak the parts or use a mixture of baking soda and water. Avoid abrasive cleaners that could damage the surface.
Check and Use Proper Liners
- Ensure you are using liners designed for your COSORI model, such as the Cosori Air Fryer Liners or similar products.
- Never place liners during preheating, as they can fly up and contact the heating element.
- Place food evenly on liners to prevent them from flying up.
Adjust Usage Habits
Do not overfill the basket—leave space for hot air to circulate. Use the recommended temperature settings and avoid preheating with liners in place.
Perform Regular Maintenance
Clean the heating element and interior after each use. Regular maintenance prevents grease buildup, reducing smoke risk over time.

Frequently Asked Questions
Can I use foil or liners to prevent smoke?
Yes, but only use oven-safe, non-flammable liners like the Cosori air fryer liners or parchment paper liners. Never preheat with liners in place, and ensure food covers them to prevent contact with the heating element.
Why is my air fryer smoking even after cleaning?
Residual grease or food debris in the heating element or basket can cause smoking. Regular cleaning and avoiding overfilling can prevent this.
Is it safe to run the air fryer empty to burn off residue?
It’s generally safe to run the air fryer empty at high temperature for a few minutes to burn off residue, but monitor closely and ensure proper ventilation. Always unplug afterward to inspect or clean.
How often should I clean the heating element?
Inspect and clean the heating element after every 5-10 uses or when you notice smoke or residue buildup. Use a soft brush or cloth to remove any grease or debris.
