What You'll Learn
Some electric wall ovens are PFAS-free
Per- and poly-fluoroalkyl substances, or PFAS, are a group of synthetic chemicals that have been linked to various health and environmental risks. PFAS are commonly used in non-stick coatings and other consumer products due to their grease and water-resistant properties. While some electric wall ovens may contain PFAS, it is important to note that there are PFAS-free alternatives available.
Toaster oven fryers, for example, are marketed as being free of PFAS, as well as other chemicals such as BPA, PTFE, PFOA, and lead. These ovens typically have anodized aluminum interior walls, with stainless steel fry baskets and oven racks. While they may not have a non-stick coating, they offer a safer alternative for those concerned about the potential hazards of PFAS.
Another PFAS-free option is the Panasonic 1.2 Cu. Ft. 1200-Watt Countertop Microwave Oven with Inverter Technology. This oven is specifically mentioned as containing no PFAS, although it does contain other chemicals listed on the California Department of Toxic Substances Control's Candidate Chemical list. This transparency in chemical disclosure is essential for consumers making informed decisions.
The Elite oven, represented by GreenPan, is another example of a PFAS-free option. The interior of the oven is made of galvanized steel, while the oven and broiler racks are stainless steel. The crumb tray, basket, baking, and pizza accessories are ceramic-coated over aluminum, eliminating the need for chemicals like PTFE, PFOA, or any other type of PFAS. GreenPan also assures that their products are BPA-free and do not contain any nanoparticles that could leach into food during cooking.
While these PFAS-free options exist, it is important to exercise caution when purchasing "non-toxic" cookware. Some manufacturers may make misleading claims about their products being "PFOA-free" or ""FDA-approved," without disclosing the presence of other PFAS chemicals. It is always advisable to conduct thorough research and consult trusted sources before making a purchase, especially when considering the potential health and environmental implications.

PFAS-free alternatives to electric wall ovens
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been linked to various health and environmental risks. These chemicals are often found in non-stick coatings on electric wall ovens and other cookware, but there are PFAS-free alternatives available.
One option for a PFAS-free electric wall oven is the Panasonic 1.2 Cu. Ft. 1200-Watt Countertop Microwave Oven with Inverter Technology. This oven is made of stainless steel and does not contain any PFAS, according to the manufacturer. It is important to note that the oven may contain other chemicals listed on the California Department of Toxic Substances Control's Candidate Chemical list, but Panasonic provides a link for more information on these substances.
Another option for a PFAS-free oven is the GreenPan Elite Convection Air Fryer Oven. This oven has a non-stick coating that is silica-based, rather than PFAS-based. The interior of the oven is made of galvanized steel, while the oven racks and broiler rack are stainless steel. The crumb tray, basket, baking, and pizza accessories are ceramic-coated over aluminum. GreenPan states that their Thermolon coating does not contain any nanoparticles, so there is no risk of them leaching into food during cooking. However, it is worth noting that GreenPan did not disclose how they galvanize their steel, which may be a concern for some consumers.
In addition to these specific PFAS-free options, there are also materials that are inherently PFAS-free, such as cast iron, carbon steel, and stainless steel. For example, the Calphalon cast-iron pan and the Matfer Bourgeat Black Carbon Steel pan are both rated highly for their cooking performance and ease of cleaning. These types of pans can often be used on the stovetop and in the oven, providing versatility and value.
When considering PFAS-free alternatives to electric wall ovens, it is important to be cautious of misleading claims. Some companies may market their products as ""PFOA-free" or "FDA-approved," but these statements do not always mean that the product is completely free of PFAS. It is always a good idea to do your own research and look for independent testing or reviews that support the manufacturer's claims.

PFAS in non-stick coatings
PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals that have been linked to various health and environmental risks. They are often used in non-stick coatings on cookware due to their ability to repel grease and water. However, it is important to note that not all non-stick coatings contain PFAS, and some products may claim to be PFAS-free when they are not.
A study by the Ecology Center found that undisclosed PFAS coatings are common on cookware, with 79% of tested non-stick cooking pans and 20% of tested non-stick baking pans coated with PTFE (polytetrafluoroethylene), a polymer form of PFAS. PTFE, also known as Teflon, is typically made using several hazardous PFAS that have been linked to the pollution of drinking water worldwide. The study also found that product claims and omissions on packaging could mislead buyers into purchasing PTFE-coated pans when they believe they are buying a PFAS-free alternative. For example, while pans labelled "PTFE-free" were indeed free of PFAS, those labelled "PFOA-free" did not necessarily mean PFAS-free.
To address this issue, organisations like the Green Science Policy Institute have compiled lists of PFAS-free products to help consumers make informed choices. Additionally, some manufacturers have started using ceramic coatings, which offer a relatively non-stick surface without the toxic chemical load associated with PFAS. However, ceramic coatings are known for having shorter lifespans than their PFAS-coated counterparts.
It is worth noting that even if PFAS do not become gases in the oven, there are still concerns about their use during disposal. Certain PFAS can persist in the environment for extended periods and contaminate groundwater and drinking water. Furthermore, specific PFAS can accumulate in living organisms, leading to toxic effects, including reproductive toxins, carcinogens, and endocrine disruptors.
While some toaster oven fryers and air fryer ovens are marketed as being BPA, PTFE, PFOA, PFAS, and lead-free, it is important to carefully review product specifications and conduct personal research to ensure the absence of these chemicals.

Health risks of PFAS
PFAS, a group of manufactured chemicals, have been used in various industries and consumer products since the 1940s due to their unique properties. While PFAS have beneficial applications, they also pose significant health risks.
One of the primary concerns with PFAS is their persistence in the environment and their ability to accumulate in living organisms, including humans, animals, and plants. Certain PFAS have been identified as having long-lasting effects in the environment, contaminating groundwater and drinking water sources. This contamination leads to human exposure through drinking water and the consumption of affected plants and animals.
The health risks associated with PFAS exposure are wide-ranging and can affect multiple systems in the body. Some of the potential health effects include:
- Reproductive issues: PFAS exposure has been linked to decreased fertility and increased high blood pressure in pregnant women, which can lead to pre-eclampsia.
- Developmental delays in children: Exposure to PFAS may result in low birth weight, accelerated puberty, bone variations, and behavioral changes in children.
- Increased cancer risk: Certain PFAS have been associated with an elevated risk of developing specific types of cancers, including prostate, kidney, and testicular cancers.
- Immune system dysfunction: PFAS exposure can reduce the body's ability to fight infections and decrease vaccine response, leading to overall immune suppression.
- Increased cholesterol levels: Studies have suggested a link between PFAS exposure and higher cholesterol levels, which can contribute to cardiovascular issues.
- Risk of obesity: There is a potential association between PFAS exposure and an increased risk of obesity.
- Endocrine disruption: Certain PFAS have been identified as endocrine disruptors, which can lead to hormonal imbalances and related health issues.
It is important to note that the specific health effects of PFAS exposure can vary depending on the type of PFAS, the level of exposure, and individual factors. Additionally, the long-term effects of low-level PFAS exposure, especially in children, are still being studied.
While it may not be possible to completely avoid PFAS exposure, taking proactive steps to reduce exposure can help limit the potential health risks associated with these chemicals.

PFAS in drinking water
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been linked to various health problems, including cancer. PFAS are slow to break down and can accumulate in the environment and in living organisms, including humans, animals, and plants. This has resulted in PFAS contamination in drinking water, particularly in areas near military bases, airports, and industrial parks that have used PFAS for firefighting or other purposes.
In recognition of the potential health risks associated with PFAS exposure, the U.S. Environmental Protection Agency (EPA) has established Maximum Contaminant Levels (MCLs) for six types of PFAS in drinking water: PFOA, PFOS, PFHxS, PFNA, HFPO-DA, and PFBS. Public water systems are required to monitor for these PFAS and have until 2027 to complete initial monitoring. By 2029, water systems that exceed the MCLs must take action to reduce PFAS levels and notify the public. The EPA expects that its final rule on PFAS in drinking water will prevent exposure for approximately 100 million people and reduce thousands of serious PFAS-related illnesses.
Despite these efforts, there is ongoing debate and legal challenges regarding PFAS regulations. Industry groups have filed lawsuits challenging the EPA's rules on PFAS and lead in drinking water, arguing that the regulations are too stringent. These cases are pending in the U.S. Court of Appeals and could have a significant impact on public health protections. Additionally, there are concerns about the accuracy of product labelling and the potential for PFAS exposure from non-stick cookware and other consumer products.
To reduce PFAS exposure, individuals can take steps such as using recommended water filters and being cautious of products that may contain PFAS. While some companies advertise their products as ""non-toxic" or "PFOA-free," independent testing has shown that these claims may not always be accurate. For example, a study by ConsumerReports found measurable amounts of PFOA and other PFAS in a PTFE-coated frying pan that was marketed as PFOA-free.
