Air Fryer Smells Like Plastic or Burning? What to Do

If a new air fryer smells like plastic, most makers that address it call that normal at first, and the rest say a smell can appear in the first uses. The fix they give is the same in outline: remove every bit of packaging, wash the basket, then run the fryer empty with the test run in your manual. A smell that is strong, gets worse, smells electrical or comes with dark smoke is a different problem: unplug the fryer.

Below is what eight makers say, how far their burn-off settings differ, and when to stop using the appliance.

What Air Fryer Makers Say About the Plastic Smell

Each row comes from the maker’s own manual or support page. The settings are not interchangeable, so treat your brand’s row as a pointer to your own manual.

Among the makers that give a time, the spread runs from 350°F for about 5 minutes (GoWISE) to a 30-minute cycle at the highest temperature (Gourmia). The Ninja row covers the AF100 only; other Ninja models have their own guides. For one of Instant’s small basket models, see the Instant Vortex Mini 4-quart review.

Why a New Air Fryer Smells Like Plastic

Philips points to the materials: plastic housing and drawer, and a PTFE-coated pan and basket heating up for the first time. COSORI’s manuals and Swan point to residue from manufacturing, and COSORI’s blog adds packaging left behind, such as stickers, plastic film, foam inserts or tape.

PTFE is not in every basket: Ninja says the AF100 basket coating is PTFE-free ceramic, and Philips itself also names the plastic housing. For more on coating types, see what to do when an air fryer basket coating flakes.

Is the Plastic Smell Harmful?

That has not been established either way. Gourmia is the only maker here that calls the smell harmless; COSORI, Chefman and Swan call it normal, which is a different claim. Philips explains the materials without saying whether the smell is harmful.

I found no regulator page on air fryer first-use odour, so I cannot tell you it is safe. I would do what COSORI’s blog asks anyway: open a window or turn on a kitchen vent for the first empty cycle, and do not leave the appliance unattended.

How to Get Rid of the Plastic Smell in a New Air Fryer

1. Remove all packaging. COSORI says to remove temporary stickers and all plastic from the basket; Gourmia includes the tape securing the basket.
2. Wash the basket and crisper plate, and wipe the unit inside and out.
3. Run the test run in your manual, with the basket empty. If your manual gives none, COSORI’s blog suggests a short empty cycle at a moderate cooking temperature.
4. Let it cool and air out. Leave the basket or drawer open, since odour can be trapped in the closed drawer.
5. Repeat only if your manual allows it. COSORI’s blog says not to run repeated long high-heat cycles back-to-back unless the manual says it is safe.
6. Contact the maker if it does not fade. COSORI’s manuals say to contact Customer Support if the smell does not decrease after the test run.

How Long the Smell Should Last

Gourmia and Swan say the first few uses, and GoWISE says a few minutes. Instant’s South African FAQ says most people do not notice the smell after the first use, though some are more sensitive to it. COSORI’s blog treats an odour in the first one to three heating cycles as usually normal, and says the timing depends on the model, materials, cleaning, ventilation and storage time. None of the makers here promises the smell will be gone by a set number of uses.

When to Stop and Unplug the Air Fryer

COSORI’s blog lists the signs that mean unplug it and let it cool:

• Smoke that is not clearly from food.
• A strong burning or melting smell.
• Visible warping, bubbling, discoloration or damaged parts.
• Electrical smells, sparks or unusual noises.
• A smell that continues after several proper cleaning and empty heating cycles.

COSORI, Gourmia, Instant and Ninja all say to unplug immediately if you see dark or black smoke, and COSORI’s manuals say dark smoke means food is burning or there is a circuit problem. White smoke is different: COSORI calls white smoke from heating fat or splashing food normal. If you can see smoke as well as smell it, why an air fryer smokes goes through the causes.

COSORI’s blog also says not to repair electrical or heating parts yourself. If the maker confirms a fault and the fryer is out of warranty, the best air fryers guide covers replacements.

Why an Older Air Fryer Smells Like Burning

COSORI’s blog says a smell that appears after several uses may not be a new-appliance smell at all. Swan’s checklist: switch off, unplug and let it cool fully, check the heating element for grease, food residue or debris, and check that no packaging, paper or plastic has touched the element. If the smell continues after that, Swan says to contact its customer service.

The Instant 10-qt oven manual warns that splatter built up around the element risks smoke and fire, and says that if you smell smoke, touch Cancel and unplug. Cleaning the element is covered in how to clean an air fryer. COSORI also says never to put parchment in without food on top, because the air can lift it onto the heating coils; the liner rules are in can you put parchment paper in an air fryer.

Common Mistakes, and the Lemon Debate

The usual mistakes are a missed piece of film or foam, and cooking while the smell is still strong, which COSORI’s blog says not to do. The lemon trick is less clear-cut, because COSORI disagrees with itself.

COSORI’s UK FAQ suggests heating sliced lemons at 200°C if a smell lingers, yet the UK guide that same FAQ links to says to avoid heating lemon juice or acidic mixtures unless your manual says it is safe. Neither COSORI manual I read mentions lemon at all.

Instant goes the other way. Its South African Vortex FAQ, passing on advice from Instant’s global head office, says to put 2 cups of water, 1/4 cup of white vinegar and a cut-up lemon in the drawer, run the highest temperature for 20 minutes and leave it to cool overnight. COSORI’s blogs say not to treat vinegar as a universal fix, and Instant’s manuals mention vinegar only in a cold baking soda spray for grease. I would use any of these methods only if your own manual names it.

Check Whether Your Air Fryer Has Been Recalled

A burning or melting smell can also be a known fault. The US Consumer Product Safety Commission’s recall 23-130 covers about 2 million COSORI air fryers in 3.7 and 5.8 qt sizes, because a wire connection can overheat. CPSC recall 24-159 covers about 187,400 Insignia air fryers and air fryer ovens, which can overheat and melt or break the handles.

Both notices say to stop using the recalled units immediately. The model number is on the label underneath, so compare it with the list on each notice.

How This Page Was Put Together

This page is based on maker manuals, maker support pages and two CPSC recall notices, not on testing; I do not own or test air fryers. Beyond the sources linked above, it draws on COSORI’s US blog, its UK blog and a second Swan page.

What I could not establish: whether the first-use smell is harmful, what the manufacturing residue is, and how many uses it takes to go. Maker pages change, so treat your own manual as the final word.

The Verdict

A mild plastic smell from a new air fryer is what the makers that address it expect, and the cure is unpacking fully, washing, and the empty test run in your own manual. A strong, worsening or electrical smell, or dark smoke, means unplug it and contact the maker, after checking the recall notices. For every other guide on the appliance, see the air fryer hub.

Frequently Asked Questions

Why does my new air fryer smell like plastic?

Makers give two reasons. Philips says the plastic housing and PTFE-coated basket can release some smell during the first uses, and COSORI and Swan put it down to manufacturing residue burning off. Packaging left inside is the other common cause, so check for film, tape and foam.

Is it safe to use an air fryer that smells like plastic?

Gourmia calls the first-use smell harmless, and COSORI, Chefman and Swan call it normal, but I found no regulator ruling either way. I would run the empty test run with a window open first, and not cook while the smell is strong or getting worse.

How long does the new air fryer smell last?

Makers say the first few uses; GoWISE says a few minutes. None of them gives an exact number. If the smell is still strong after several cleaning and empty cycles, COSORI’s blog says to contact customer support rather than carry on using the fryer.

Does lemon get rid of air fryer smells?

COSORI gives both answers: its UK FAQ suggests sliced lemons at 200°C for 15 minutes, while its blogs say to avoid heating lemon or acidic mixtures unless your manual allows it. Instant’s South African FAQ suggests a lemon, vinegar and water cycle. I would follow your own manual.

Why does my air fryer smell like burning plastic?

On an older fryer, check for packaging, paper or plastic touching the heating element, and for grease on it, with the fryer unplugged and cool. If the smell is electrical, comes with dark smoke or will not go after cleaning, stop using it and contact the maker.

Is my air fryer part of a recall?

Check the model number on the label underneath against the CPSC notices. Recall 23-130 covers about 2 million COSORI air fryers for an overheating wire connection, and recall 24-159 covers about 187,400 Insignia air fryers and ovens. Both notices say to stop using the recalled units.
