Check and Clean the Basket and Trays
- Remove the basket and trays from the air fryer.
- Wash them thoroughly with warm soapy water, paying close attention to any grease or food buildup.
- Dry all parts completely before reassembling.
Use Appropriate Liners and Avoid Overfilling
Use only liners compatible with your COSORI model, such as the Cosori Air Fryer Liners or other FDA-approved liners. Never preheat with liners in the basket to prevent trapping heat.
Do not overfill the basket — leave space for proper air circulation to prevent excess smoke from trapped grease or juices.
Prevent Oil and Food Residue Buildup
Apply a light coating of oil when needed, and wipe away excess grease after each use. Regularly clean the interior surfaces, including the heating element, to prevent residues that can burn and produce smoke.
Ensure Proper Use During Preheating
Always preheat your air fryer with an empty basket without liners or food to burn off any residual grease or food particles. Avoid preheating with liners in place, as this can cause overheating and smoke.
