Air fryers are generally very safe appliances, but like any kitchen tool that generates high heat, there are important safety rules to follow. These 10 guidelines will keep you safe and extend the life of your air fryer.
Rule 1: Give It Room to Breathe
Your air fryer needs at least 5 inches of clearance on all sides, especially behind the exhaust vent. Never operate it: - Under cabinets or shelves - Against a wall (blocking the vent) - Near curtains, paper towels, or anything flammable - On a stove top (the burners could accidentally turn on)
Rule 2: Always Use It on a Heat-Resistant Surface
The bottom and sides of an air fryer get hot during operation. Place it on: - Stone or granite countertops - A heat-resistant mat or trivet - A wooden cutting board (as a buffer)
Never use it on a plastic surface or tablecloth.
Rule 3: Never Use Aerosol Cooking Sprays
Aerosol sprays (like PAM) contain propellants that damage the non-stick coating on your air fryer basket over time. Instead, use a refillable oil sprayer with regular olive or avocado oil.
Rule 4: Do Not Overfill the Basket
Overcrowding is not just a cooking mistake — it is a safety issue. Too much food blocks airflow, which can cause: - Uneven cooking (cold spots where bacteria survive) - Excess smoke from trapped grease - Food touching the heating element
Rule 5: Never Cook Anything with a Wet Batter
Liquid batter (like beer batter) will drip through the basket, pool at the bottom, and create smoke. Only use dry breading (flour, breadcrumbs, panko) in the air fryer. If you want battered food, freeze it first so the coating sets.
Rule 6: Drain Grease from the Drip Tray
When cooking fatty foods (bacon, chicken thighs, sausages), grease collects in the drip tray below the basket. If it builds up excessively, it can smoke or potentially catch fire. Drain the tray between batches when cooking high-fat foods.
Rule 7: Check Food with a Meat Thermometer
Do not guess whether meat is cooked through. Use an instant-read meat thermometer and cook to these internal temperatures: - Chicken: 165°F (74°C) - Pork: 145°F (63°C) - Beef (medium-rare): 130°F (54°C) - Fish: 145°F (63°C)
Rule 8: Unplug When Not in Use
Always unplug your air fryer after use. This prevents accidental activation and reduces the risk of electrical issues.
Rule 9: Clean After Every Use
Grease buildup causes smoke and can become a fire hazard over time. After every use: - Wash the basket and drip tray with warm soapy water - Wipe down the interior with a damp cloth - Check and clean the heating element periodically

Rule 10: Never Submerge the Base in Water
The base unit contains electrical components. Only the removable basket, tray, and accessories should be washed with water. Wipe the base with a damp cloth only.
Bonus: What to Do If Your Air Fryer Smokes
Smoking usually means one of three things: 1. Excess grease — drain the tray and reduce fatty foods 2. Food debris — clean the basket and heating element 3. Too much oil — use less oil next time
If you follow these rules, your air fryer will serve you safely for years. Need help choosing a safe, reliable model? Check our expert reviews.
