A new air fryer that smells like plastic is usually normal. The plastic housing, the nonstick basket coating and leftover factory residue give off an odor the first few times the unit gets hot, and it fades with a few empty test runs, good ventilation and a wash. A plastic smell that shows up later, or comes with dark smoke, is a different story and means you should unplug the unit.
This guide explains where the smell comes from, the exact steps to clear it, how to tell harmless break-in odor from a real problem, and what to do if the smell will not go away.
TL;DR
- A faint plastic or chemical smell during the first few uses is common and is caused by the plastic housing and the nonstick-coated basket heating up, according to Tom’s Guide.
- Remove all packaging, wash the basket and tray, then run the empty unit hot in a well-ventilated spot. Repeat until the smell is gone.
- Smell that returns later in the unit’s life, usually means old grease or a part touching the heating element, not new-appliance odor.
- Dark smoke, a hot cord or plug, or a smell of truly burning plastic means unplug it, let it cool and call the manufacturer.
- Never use a recalled or damaged air fryer. Check the U.S. Consumer Product Safety Commission (CPSC) recall list for your model.

Why a new air fryer smells like plastic
An air fryer is a small oven with a powerful heating element and a fan, wrapped in a plastic shell, with a nonstick-coated basket inside. Almost every material in it is new, and new materials carry traces of manufacturing: mold-release agents, protective oils, adhesives, and the coating itself, which is baked onto the basket at the factory.
When you run it for the first time, the element heats quickly and the fan pushes hot air across all of those surfaces. Anything volatile on them evaporates, and you smell it. That process is what people call off-gassing. It is the same reason a new shower curtain, a new car or a new set of cookware can smell strongly for a while.
Tom’s Guide notes that it is common for an air fryer to smell of plastic during its first few uses, and that the plastic housing and the PTFE-coated basket are the usual causes once the appliance reaches high temperatures (Tom’s Guide). Tasting Table adds useful context: ideally the manufacturer would heat each unit before it ships, but time pressure at the factory often means some residual odor is left for the buyer to clear (Tasting Table).
The usual suspects, part by part
| Source of the smell | What it smells like | When it shows up |
|---|---|---|
| Plastic housing, handle and vents | Hot plastic, sometimes slightly sweet | First 3 to 5 uses, strongest while preheating |
| Nonstick-coated basket and tray | Chemical, “new pan” odor | First uses, stronger on an empty, hot unit |
| Packaging residue (tape, foam, film) | Sharp, burnt-plastic | The first time the element heats, if anything was left inside |
| Factory oils and protective coatings on the element | Oily, metallic | First runs, fading quickly |
| Old grease on the element or fan housing | Stale, acrid, “burnt” | Any time after weeks or months of use |
The first four are break-in sources and should fade. The last one is a cleaning problem, which we cover below.
How to get rid of the plastic smell: step by step
These steps work for most new units. Always follow your own manual first, because temperatures and run times differ by model.
1. Unpack everything
Take out every piece of packaging from inside and around the unit: foam, plastic film on the basket, cardboard under the tray, twist ties, and any sticker on the heating area. A bit of leftover film or tape is one of the most common reasons a brand-new air fryer smells like burning plastic. The COSORI manual says to remove all packaging first and, if needed, clean the heating coil of food debris, and to contact Customer Support if a plastic smell remains after a test run (COSORI TurboBlaze manual). That manual is for one model, but the logic applies to any air fryer.
2. Wash the removable parts
Wash the basket and rack in hot, soapy water and wipe the base and sides with the same solution. Avoid metal utensils and harsh scrubbers, which can scratch the coating, a point Tom’s Guide makes as well (Tom’s Guide). Dry everything fully before putting it back. If you want the full routine for the basket, our guide to cleaning an air fryer basket without wrecking it walks through it.
3. Ventilate the room
Open a window, turn on the range hood and, if the weather allows, place the unit near an open door or on a porch or patio. Tom’s Guide recommends doing the first test run in a well-ventilated area so any residual fumes disperse (Tom’s Guide). Keep pets, especially birds, out of the room. Birds are known to be very sensitive to fumes from heated nonstick coatings.
4. Run it empty, hot, and for a while
Put the empty basket in, set the temperature to the maximum your manual allows (many models top out around 400°F) and run it for 10 to 15 minutes. Some manufacturers publish similar guidance, for example 10 to 15 minutes at a high setting, repeated three or four times before the smell is gone. Let the unit cool completely between runs.
Two cautions apply here:
- Do not exceed the maximum temperature in your manual. Nonstick PTFE coatings begin to break down above about 500°F, according to Poison Control, and normal air fryer settings are designed to stay well below that.
- Never leave the unit running unattended in a closed room. Stay close, and stop the run if you see smoke.
5. Repeat, then cook something
Most people find the smell drops sharply after the second or third run. Once it is barely noticeable, cook something strongly flavored the first time, such as potato wedges or chicken thighs. Strong food aromas cover any faint leftover note, and the first real cook helps seat the coating.
Quick fixes people ask about
- Lemon or vinegar in the basket. Some people wipe the basket with diluted white vinegar or a lemon slice after washing. It helps with stale smells, though it will not remove a manufacturing odor that is still baking off. Rinse well and dry.
- Baking soda. A paste of baking soda and water on the basket, rinsed off after a few minutes, helps lift grease odor. Do not scrub a nonstick surface hard.
- Taking it outside. Some owners run the first test cycle in the yard or garage. If you have a safe, dry, covered outlet and the unit is supervised, it keeps fumes out of your living space. Keep it dry and never use an extension cord not rated for the load.
How long does the smell last?
For most people, a few uses. A reasonable expectation is that the odor fades over the first three to five runs, with the strongest smell during the first one or two. If you are still smelling plastic after five or six full hot cycles, or the smell is getting stronger instead of weaker, stop guessing and check the signs in the next section.
If you bought a larger or more powerful model, the smell can seem stronger simply because more heating element and more coated surface are working at once. Size matters for airflow too: an air fryer that is too small for the amount of food, or one that is overfilled, runs less efficiently. The USDA advises against overfilling the basket, since crowding limits air circulation and causes uneven cooking (USDA FSIS). Our air fryer size guide helps you pick the right capacity for your household.
Normal smell or warning sign?
Use this as a rough sorting tool. It is not a replacement for your manual.
| What you notice | Most likely cause | What to do |
|---|---|---|
| Mild plastic or chemical odor on first 3 to 5 uses, fading each time | Normal break-in | Ventilate, run empty cycles, wash parts |
| Sharp plastic smell on first run, then gone after removing film | Leftover packaging | Unplug, cool, remove packaging, rerun |
| Smell returns after cooking greasy or sugary food | Grease or sauce residue | Deep clean basket, tray, and under the element |
| Smell stays strong after many hot cycles | Possible defect | Stop using, contact customer support |
| Dark smoke | Burning food or an electrical problem | Unplug immediately, wait for smoke to clear |
| Hot or damaged cord or plug, melted housing | Hardware fault | Stop using, contact the manufacturer, check recalls |
A new-appliance odor is usually most noticeable when the unit is empty and heating up, and it should get weaker every time. A smell of genuinely burning or melting plastic that gets stronger is not off-gassing.
When the smell comes back months later
A plastic smell that appears later in the life of your air fryer is rarely about the factory. It typically comes from one of three things.
- Grease and food debris near the heating element. The COSORI manual explains that food particles and grease, especially under the heating element, can burn and produce persistent smoke or odors, so keep the unit clean to prevent odors and fire hazards (COSORI TurboBlaze manual). After the unit is unplugged and fully cool, wipe the element and the area around it with a damp, soapy cloth.
- Something touching the element. Parchment, foil or a liner that lifts in the airflow can touch the element and scorch. Use only liners that are perforated and weighted down by food. Our piece on preventing air fryer liner fires with perforated silicone explains how.
- Worn or damaged parts. A cracked handle, warped basket or coating that is flaking all deserve attention. A scratched, peeling basket should be replaced rather than used.
If the smell is more of an overall burnt odor than plastic, our guide to the air fryer burnt smell covers causes and fast, safe fixes. If you see smoke while cooking, read what to do when an air fryer is smoking and the longer explainer on why an air fryer keeps smoking.
Is the smell harmful?
A short-lived new-appliance smell in a ventilated room is not generally considered a hazard, and it is the reason manufacturers tell you to run a test cycle first. The thing to avoid is overheating nonstick coatings.
Poison Control explains that “Teflon flu” (polymer fume fever) comes from inhaling fumes from burning polymer products, usually overheated nonstick cookware. Symptoms include chills, fever, fatigue, headache, body aches, chest tightness and airway irritation (Poison Control). Its advice is to keep the kitchen well ventilated and to avoid high temperatures with nonstick cookware, because PTFE coatings begin to break down above about 500°F (Poison Control).
Practical takeaways:
- Stay within the temperature range in your manual.
- Do not run the unit empty for long stretches beyond the break-in runs your manual recommends.
- Ventilate during the first uses.
- If anyone in the home develops flu-like symptoms, chest tightness or breathing trouble after exposure to fumes, call Poison Control at 1-800-222-1222 or seek medical care. Do the same for children, people with asthma and anyone who is pregnant if they react to the smell.
You may also see air fryers advertised as using no PTFE, with ceramic or stainless steel baskets. If coatings worry you, those are worth browsing. Note that they can still have a brief new-appliance smell from the plastic housing and factory residues.
When to stop using the air fryer
Some situations are not troubleshooting. They are reasons to stop.
- Dark smoke. The COSORI manual says dark smoke means food is burning or there is a circuit problem. Unplug the unit right away and wait for the smoke to clear before removing the basket. If the cause is not burnt food, contact customer support (COSORI TurboBlaze manual).
- A damaged cord, plug or body. Do not use a damaged or malfunctioning unit, or one with a damaged cord or plug. Contact customer support (COSORI TurboBlaze manual).
- A persistent plastic smell after test runs. If it remains after the test run, the manual says to contact customer support.
- A fire inside the unit. The National Fire Protection Association (NFPA) advises turning off the heat and keeping the door closed until the appliance is cool, opening it only when you are sure the fire is out. After any appliance fire, a licensed professional should check or service the unit before it is used again (NFPA). For a fire you cannot immediately control, get everyone out and call 911.
Check for recalls
If a plastic smell comes with overheating, melting or a handle that softens, check whether your model has been recalled. In 2024 the CPSC announced a recall of certain Insignia air fryers and air fryer ovens because they could overheat, melt or break handles, and shatter oven doors, creating fire, burn and laceration hazards (CPSC). Consumers with those units were told to stop using them immediately and follow the recall instructions for a refund (CPSC).
Search your brand and model on CPSC’s recall page whenever you buy a new unit, and again if it starts behaving oddly. The model number is on the label on the bottom or back.
When you shop, it is also worth looking for appliances that are certified. NFPA says heating and cooking equipment should be listed by a nationally recognized testing laboratory (NFPA). The listing mark, such as UL or ETL, is usually on the rating label and the product page.
Our perspective: smell is a design and quality signal
We look at air fryers the way a home cook does. A new one should be a pleasure to open, not something you have to air out for a week. When we curate air fryers, we favor models that are easy to clean, with removable parts that wash without fuss and baskets that are straightforward to reach, because most smells that come back after the first week are a cleaning problem, and a machine you can clean easily is a machine you will keep clean.
We also think the first-use ritual is worth embracing rather than resenting. Washing the parts, running one or two empty cycles with the window open, and then cooking something simple takes about 45 minutes in total, and it gives you a baseline: you learn how your unit smells and sounds when it is healthy. That makes any change obvious later.
Our advice when choosing: pick the right size for your household, read the manual’s break-in instructions, look for a listing from a recognized testing lab, and check the recall list before you buy. A well-made air fryer that fits your kitchen is built to give you fast, healthier meals without the guesswork. See how that fits into daily life in our piece on why air fryers save time in the kitchen.

Shopping for an air fryer you will enjoy using
If your current unit still smells after repeated test runs, or you are replacing one you no longer trust, we keep a curated selection of air fryers chosen for style, ease of use and easy cleanup. Browse them on our air fryers page, where you can compare options and follow through to the retailer.
If you are deciding between a single and a dual-basket design, our dual basket air fryer review looks at whether the counter space is worth it.
Habits that keep the smell away for good
A few simple habits do more than any hack.
- Wipe after every use. Once the basket has cooled, wash it with hot, soapy water. Grease baked on repeatedly is the biggest source of a stale burnt smell.
- Check the element monthly. With the unit unplugged and cool, turn it upside down and wipe the area around the element with a damp cloth. Remove crumbs and splatter.
- Do not overfill. Crowded food drips grease on the element and blocks airflow. The USDA’s guidance on not overfilling the basket is about even cooking and safety alike (USDA FSIS).
- Go easy on oil sprays and sugary glazes. They leave a sticky film that smokes the next time the unit heats. If you use spray, wash the basket thoroughly afterward.
- Preheat only when it helps. Some recipes benefit and some do not. Our guide to whether you need to preheat an air fryer explains when it matters, and you should never preheat a unit with food residue still in it.
- Avoid common mistakes. Blocked vents, loose liners and cooking right against a wall all cause trouble. Our list of 12 air fryer cooking mistakes covers them.
- Leave space around the unit. Keep it on a heat-safe, level surface with room around the vents, as your manual specifies.
What about other cookware that smells?
New nonstick pans can give off a similar first-heat odor. The same rules apply: wash first, ventilate, stay within the maker’s temperature limit and do not preheat an empty pan on high. If you are updating your cookware as well, see what to know before upgrading your cookware set or browse our cookware sets.
FAQ
Is it normal for a new air fryer to smell like plastic?
Yes. A faint plastic or chemical smell during the first few uses is common, because the plastic housing and the nonstick-coated basket give off odor as they reach high temperature. It should get weaker with each run. If it does not fade after several hot test cycles, contact the manufacturer.
How do I stop my air fryer from smelling?
Remove all packaging, wash the basket and tray in hot, soapy water, then run the empty unit at a high setting for 10 to 15 minutes in a ventilated room. Repeat as needed, letting it cool between runs. For later smells, clean the basket and the area around the heating element.
Is air fryer off-gassing dangerous?
A brief new-appliance odor in a ventilated room is generally not the concern. The real risk is overheating nonstick coatings: Poison Control notes that PTFE starts to break down above about 500°F and that fumes can cause flu-like symptoms. Stay within your manual’s limits, ventilate, and call Poison Control at 1-800-222-1222 if anyone becomes ill.
My air fryer smells like burning plastic. What should I do?
Unplug it and let it cool. Look for leftover packaging, film or a liner touching the element, and clean any food debris from the heating area. If the smell remains after a test run, or you see dark smoke, stop using it and contact the manufacturer’s customer support. Also check CPSC recalls for your model.
Can I use the air fryer if the smell does not go away?
We would not. If a plastic smell lasts through several hot test runs, or comes with smoke, a hot cord or a melted part, stop using it and contact customer support about a repair, replacement or refund. A unit that smells strongly after a proper break-in may have a defect.
