Is It A Myth Or Reality That Toaster Ovens Emit Toxic Emissions?

Toast, a simple yet beloved breakfast staple, is often prepared using the trusty toaster oven. But have you ever wondered if your toast has a side of toxic emissions? I’ve seen a question swirling around for years about whether toaster ovens emit harmful chemicals. Many people wonder whether their morning toast is worth the potential health risks.

In today’s article, I’m with you, Tammy E. Edison, as a kitchen appliance specialist. Today, I’ll tell you the science behind toaster oven emissions. Also, I will tell you some truths and lies that you don’t know now.

First of all, I will clear Three sources of toaster oven emissions.

3 Sources of Toaster Oven Emissions

I have found information from many studies that toaster ovens can emit toxic substances. From our research team, we have a post on the topic Are taster ovens toxic” I hope you will get more information from this post. However, there are three, which I’m sharing below:

Heating elements and electrical components

You will be surprised to know that these components can release volatile organic compounds (VOCs) when heated. VOCs are a class of chemicals that irritate the lungs and airways. Not only that, the American Lung Association says in a report that (VOCs) can even cause cancer.

Food particles and oils

Heated food particles and oils can decompose, releasing harmful substances like acrolein. Acrolein is a known irritant that can cause respiratory distress. The popular forum site “Wikipedia” states that “Acrolein is a toxic chemical and is a strong irritant to the skin, eyes, and nasal passages.

Non-stick coatings

Some toaster ovens have non-stick coatings that contain perfluorooctanoic acid (PFOA). PFOA is a chemical that has been linked to an increased risk of certain types of cancer.

Now, I am going to tell you about the misconceptions or myths about toaster oven emissions.

What Are the Misconceptions About Toaster Oven Emissions – (7 Myths)

Below, I’m telling you about seven misconceptions. Know the truth about these misconceptions, and be careful.

Myth 1: Toaster ovens emit harmful chemicals with every use

Reality: Toaster ovens can emit some chemicals, but the amount is usually very small and unlikely to cause harm. Emission levels can vary depending on the type of toaster oven, the food being cooked, and how often the oven is used. Generally, toaster ovens emit chemicals for the three reasons I mentioned above.

Myth 2: All toaster ovens emit the same amount of chemicals

Reality: The amount of chemicals emitted by a toaster oven depends on several factors, including:

  • The type of oven,
  • What food is cooked and
  • How often is the oven used?

Some toaster ovens are designed to emit fewer chemicals than others. So, the truth is that not all toaster ovens emit the same amount of chemicals.

Myth 3: Toaster ovens are only dangerous if they are old or damaged

Reality: The idea that only old or damaged toaster ovens emit harmful chemicals is false. Even new toaster ovens can emit some chemicals, although emission levels are generally lower than older ovens. This is because newer toaster ovens are often designed to emit fewer chemicals. They have new heating elements and non-stick coatings that don’t release harmful substances.

But it’s true, and I’ve found that damaged toaster ovens emit more chemicals than new, undamaged ones. Because, damage to the heating element or non-stick coating releases more harmful substances. For example, if the non-stick coating of a toaster oven is cracked or chipped, it releases more PFOA. Which is a chemical associated with cancer.

Myth 4: Toaster ovens are only dangerous if they are used in a closed room

Reality: The United States Environmental Protection Agency reports that ventilation helps reduce the level of chemicals in the air by reducing pollutant levels. Toaster ovens can emit some chemicals even if used in a well-ventilated room. Toaster ovens emit chemicals called VOCs. These chemicals evaporate easily and become airborne. Even if a room has plenty of fresh air, VOCs can still build up to levels harmful to human health. (Although (VOCs) discussed above.)

Myth 5: There is no way to reduce the amount of chemicals emitted by toaster ovens

Reality: Absolutely right. Even though we can’t fully stop chemicals from being emitted by the toaster oven. But I can help you with some practical steps. Follow my simple five steps to decrease the release of harmful chemicals greatly.

  • Choose a Low-Emission Toaster Oven
  • Minimize Toaster Oven Usage
  • Regular Cleaning and Maintenance
  • PFOA-Free Non-Stick Coating
  • Adequate Ventilation

Myth 6: Toaster ovens emit harmful chemicals even when they are not being used

Reality: Toaster ovens only emit harmful chemicals when turned on and heated up. Once the oven attains the target temperature, the emissions will come to a halt.

Myth 7: Toaster ovens are only dangerous for people with respiratory problems

Reality:  Right! People with breathing problems like asthma or allergies can be more affected by the chemicals from toaster ovens. When cooking, certain chemicals called volatile organic compounds (VOCs) are released. These chemicals can irritate your airways and lungs. This can make you cough, wheeze, or have trouble breathing. Even short-term exposure to these chemicals can trigger respiratory issues. Especially for those with pre-existing conditions.

Are There Identifiable Sources of Misinformation Regarding Toaster Ovens? 

Are There Identifiable Sources Of Misinformation Regarding Toaster Ovens?

There are several identifiable sources of misinformation regarding toaster ovens. I have divided these sources broadly into two categories:

  • Unintentional misinformation
  • Intentional misinformation

Unintentional misinformation

I have often noticed that some people often spread wrong information unknowingly. Because they don’t know what science says about toaster ovens. For example, some people may believe that toaster ovens emit harmful chemicals. Because they’ve heard that other kitchen appliances like ovens and microwaves can do that. However, emission levels from toaster ovens are generally much lower than other appliances.

Intentional misinformation

Such misinformation is spread intentionally, often with the intent to harm or deceive. For example, some companies make false claims about the safety of their toaster ovens to boost sales. But as a user and kitchen appliance expert, I can never give such misleading information. Even some people spread the wrong information about toaster ovens to keep people away from using them.

Next, I will tell you what the scientific research says about toaster ovens.

What do scientists say about toaster oven emissions?

What Does Scientific Research Reveal About Toaster Oven Emissions?

Many studies have looked at toaster oven emissions and how they can affect our health. A few days ago, I read an article, a study published in the “Journal of Environmental Science and Technology” found that VOC emissions from toaster ovens were generally low. But, certain factors, such as food type and cooking temperature, can increase emissions. A different study published in the journal Indoor Air looked at how toaster oven emissions affect people with asthma. The study showed no significant changes in breathing difficulties.


Hopefully, from the above discussion, I have clarified the myth or reality that toaster ovens emit toxic emissions. Although it is true that the toaster oven emits some toxic emissions. But if you want to take steps to reduce your exposure to these emissions, follow these steps, such as:

  • Using a low-emission toaster oven,
  • Ventilation and regular cleaning of the kitchen,
  • You can effectively protect your health and
  • Enjoy the convenience of toaster oven cooking.

So, hopefully, I have been able to provide you with comprehensive information from today’s informative post. If you have any opinions about this, you can tell me in the comment box. Each and every one of your opinions is very valuable to our team. Thanks for being with me.
