Clean the Interior Thoroughly
- Remove all accessories, such as racks and liners.
- Wipe down the interior and heating element with a damp cloth to remove grease and food residue.

- Ensure all parts are dry before reassembling.
Check and Clean the Air Intake and Exhaust
- Inspect the air intake and exhaust vents for obstructions or built-up grease.
- Use a soft brush or compressed air to clear any debris or dust.
- If available, remove and clean filters according to your model’s instructions.
Use Proper Liners and Avoid Overfilling
Always place disposable liners (such as Cosori Air Fryer Liners) to catch grease and food drips, preventing buildup. Do not overfill the basket, as excess food or grease can cause smoke and uneven cooking.
Perform a Test Run
After cleaning and checking all parts, run the air fryer empty at 400°F for 10 minutes. Observe if smoke persists. If smoke continues, repeat cleaning or inspect for damaged parts.
