Clean Your Air Fryer Thoroughly
- Unplug the unit and let it cool completely.
- Remove the basket and tray, then wash them with warm soapy water, paying special attention to corners.
- Wipe the interior, heating element, and fan with a damp cloth. Use a soft brush for stubborn grease.
- Ensure all parts are dry before reassembling.
Use Liners Properly
- Always place liners at the bottom of the basket only after adding food to prevent them from flying up during preheat.
- Use liners that are compatible with your COSORI model, like the Cosori Air Fryer Liners or Air Fryer Paper Liners, to reduce grease splatter and smoke.
- Avoid preheating with liners in place, as this can trap heat and grease, causing smoke.
Adjust Your Cooking Habits
- Don’t overfill the basket; leave space for hot air to circulate evenly.
- Use lower temperatures or shorter cook times if smoke persists, especially with greasy foods.
- Check that your food is dry before cooking to minimize splatter and smoke.
Additional Tips & Warnings
- Regularly clean the grease filter if your model has one, to prevent buildup.
- Never leave the air fryer unattended while in use, especially if you notice smoke formation.
- Use recommended accessories and avoid using aerosol sprays or non-food-grade materials inside the basket.
