If you have just unboxed a brand-new appliance and noticed a chemical odor, you are likely asking: why does my air fryer smell like plastic? This is one of the most common complaints among air fryer owners in 2026. While it can be alarming, especially when you are preparing food for your family, the “new car smell” of the kitchen world is usually a temporary issue that can be solved with a few simple steps.
As a kitchen efficiency expert based in Austin, I have tested dozens of models, from budget units to the high-end machines in my Best Air Fryers of 2026 guide. Almost all of them have a “break-in” period.
Here is the professional breakdown of why does my air fryer smell like plastic and exactly how to fix it before your next meal.

The Top 3 Reasons Why Your Air Fryer Smells Like Plastic
Understanding why does my air fryer smell like plastic starts with knowing how these machines are manufactured.
- Protective Factory Coatings: Manufacturers apply a thin layer of food-grade oil or wax to the internal heating elements to prevent rusting during shipping. When you turn the unit on for the first time, this coating burns off, creating that “burning plastic” scent.
- The “Off-Gassing” of Plastic Housing: High-heat appliances use durable plastics. During the first few heat cycles, the plastic parts can “off-gas” as they settle into their new temperature range.
- The Protective Film: Many users overlook small pieces of blue or clear protective tape hidden inside the unit or around the heating element.
5 Simple Fixes: How to Get Rid of the Plastic Smell
If you want to stop wondering why does my air fryer smell like plastic and start cooking, follow these steps:
1. The “Initial Burn-Off” Cycle
Never cook food in a brand-new air fryer immediately.
- The Fix: Take the unit outside or near an open window. Run it empty at 400°F for 20 minutes. Let it cool, then repeat once more. This forces the factory coatings to evaporate without ruining your dinner.
2. The Lemon and Vinegar Steam Bath
This is my favorite new air fryer smell hack.
- The Fix: Place a small oven-safe dish inside the air fryer basket. Fill it with 2 tablespoons of white vinegar and 1 tablespoon of lemon juice. Run the air fryer at 400°F for 10 minutes. The acid in the steam will neutralize the chemical odors.
3. Deep Clean with Dawn Powerwash
Sometimes the odor is trapped in the silicone bumpers on the tray.
- The Fix: Remove the basket and the tray. Use a high-quality degreaser (like Dawn Powerwash) and let it sit on the surfaces for 10 minutes before rinsing with hot water. Check out my guide on How to Clean a Burnt Air Fryer Basket for more deep-cleaning tips.
4. Check the Heating Element
If the smell persists, the answer to why does my air fryer smell like plastic might be physical.
- The Fix: Unplug the unit, wait for it to cool, and turn it upside down. Use a flashlight to check the heating coil for any stray pieces of plastic packaging or tape that might be melting.
5. The Charcoal Filter Method
If your 2026 model has a built-in air filter (like some newer Ninja or Instant models), ensure the charcoal filter is seated correctly. Sometimes the filter itself can have a slight odor until it has been used once or twice.
Troubleshooting Table: Air Fryer Odors
| Odor Type | Likely Cause | Is it Dangerous? | The Fix |
|---|---|---|---|
| Sharp Plastic | Factory Coating | No (if temporary) | 20-min Burn-off Cycle |
| Burning Rubber | Melting Wire/Tape | Yes (Unplug it) | Check Heating Element |
| Old Grease/Acrid | Burnt Food | No | Deep Clean Heating Coil |
| Chemical/Sweet | New Plastic Off-gassing | No | Lemon & Vinegar Steam |
Is the Plastic Smell Toxic?
A very common follow-up to why does my air fryer smell like plastic is whether the fumes are dangerous. Most reputable brands use BPA-free, food-grade plastics. While the smell is unpleasant, it is generally not toxic as long as you are doing the “burn-off” cycle in a ventilated area. However, if the smell continues after 5-10 uses, it may indicate a defective unit, and you should contact the manufacturer.
