Have you heard the term “PFAS” being thrown around and wondered, “What is PFAS?” and “Why is everyone talking about them?”
It may seem like you need a PhD to understand what PFAS are. But don’t worry. We’re breaking it down into manageable pieces.
In this guide, we’ll discuss what PFAS are, the risks they pose, where they commonly hide in your home, and most importantly, practical strategies to minimize exposure.
Spoiler Alert: PFAS are harder to avoid than you might think!
What is PFAS (Perfluorinated Alkylated Substances)?
PFAS is an acronym that describes a group of chemicals referred to as “PerFluorinated Alkylated Substances”, a large group of man-made chemicals that have been around since the 1930s.
PFAS first appeared with DuPont’s invention of Teflon, a revolutionary non-stick coating. Teflon’s remarkable ability to repel grease and grime quickly made it a household name.
PFAS have a distinct chemical makeup that makes them especially hazardous. Simply put, PFAS are carbon chains where hydrogen atoms are replaced with fluorine atoms. This unique structure gives them the non-stick, waterproof, and stain-resistant properties that companies love.
For decades, PFAS have been used in a wide range of products, from non-stick cookware to waterproof clothing, promising to make our lives easier and more convenient.
As awareness of the potential health risks linked to PFAS grows, their convenience is giving way to a disturbing reality– these “forever chemicals” pose a significant threat to our health and environment.
So what can you do? The best thing to do is to arm yourself with as much information as you can about these toxic chemicals. And we’re here to help you do just that!
We’ll get into the basics of what makes these chemicals so dangerous, explore the potential health risks they pose, and talk about how they are impacting our environment.
We’ll also tell you the most common sources of PFAS in your home, from the kitchen to the living room, and provide you with practical tips on how to reduce your exposure.

Why are PFAS called “forever chemicals”?
Unfortunately, the strong carbon-fluorine bond is also what makes PFAS so problematic. These ultra-strong bonds are practically indestructible, which is why they’ve earned the nickname “forever chemicals.”
This bond is one of the strongest in organic chemistry, allowing PFAS to resist degradation from natural processes like heat, sunlight, and microbes. In fact, PFAS can linger for thousands of years before they begin to break down.
For this reason, PFAS begin to accumulate in the environment and in our bodies over time, with some compounds having half-lives of over eight years in humans. The persistence of PFAS means that we’re constantly being exposed to them through contaminated food, water, and air.
While “forever” might sound like an exaggeration, it comes pretty darn close to describing the long-lasting nature of PFAS and the challenges we face in addressing their environmental and health impacts.
How did PFAS become so widespread?
So, what is it about PFAS that has led to their widespread use? It all comes down to their unique properties.
PFAS are highly effective at repelling both water and oil, making them ideal for use in products that need to resist moisture and stains. They are also heat-resistant, which has made them valuable in applications where high temperatures are involved like electric cables.
As the popularity of PFAS soared, companies eagerly explored new applications beyond cookware, incorporating PFAS into waterproof clothing, stain-resistant carpets and furniture, food packaging, and more.
Common Sources of PFAS In Your Home
1. Kitchen
Non-stick cookware is one of the most common sources of PFAS, particularly those made with Teflon or other PTFE coatings. While these pots and pans make cooking and cleanup easier, they can also leach PFAS into your food, especially if they’re scratched or overheated.
Food packaging such as microwave popcorn bags, pizza boxes, and fast-food wrappers, are treated with PFAS to make them grease-resistant. Some plastic food storage containers may also have PFAS in their non-stick coatings.
Kitchen textiles like stain-resistant tablecloths or oven mitts, can contain PFAS to repel water and oil.
2. Living Room & Bedroom
Water and stain-resistant sofas, armchairs, and carpets are often treated with PFAS to repel spills and stains. Water and stain-resistant curtains may also contain these chemicals.
Mattresses and pillows are often treated with PFAS to make them waterproof or stain-resistant, particularly mattresses marketed for children or people with allergies.
Clothing items, like rain jackets or waterproof shoes, can contain PFAS.
3. Bathroom
Personal care products including some brands of dental floss, shaving cream, and cosmetics like waterproof mascara and long-lasting foundation may contain PFAS. Certain hair products, particularly those designed for smoothing or anti-frizz, can also have these chemicals.
Menstrual products and disposable diapers are other potential sources of PFAS in the bathroom. Some toilet papers have even been found to contain PFAS.
4. Children’s Items
Toys like stuffed animals, particularly those marketed as stain-resistant or waterproof, may have PFAS in their materials.
Changing pads and crib mattresses are other potential sources.
Clothing items like water-resistant jackets, bibs, or shoes can also expose children to PFAS.
Art supplies like certain markers or paints, might have these chemicals.
5. Other Household Sources
Outdoor gear, like tents, sleeping bags, and water-resistant clothing, is a common source. Some cleaning products, particularly those designed for stain removal, may also contain PFAS.
In the garage or shed, you might find PFAS in certain paints, wood finishes, sealants, and lubricants. Water-resistant fabrics used for outdoor furniture or accessories can also be a source.
What are the health risks of PFAS exposure?
Cardiovascular and Metabolic Effects
Increased Cholesterol Levels: Studies have shown that exposure to certain PFAS, particularly PFOA, PFOS, PFNA, and PFDA, can lead to higher levels of cholesterol in the blood which can lead to heart disease and other cardiovascular issues.
Changes in Liver Enzymes: PFAS exposure can lead to liver damage by accumulating in liver cells, disrupting normal liver function, and inducing oxidative stress, inflammation, and cellular damage, ultimately potentially causing conditions such as fatty liver disease, liver fibrosis, and even liver cancer.
Reproductive and Developmental Effects
Decreased Fertility: Some studies have suggested that PFAS exposure may be associated with reduced fertility in both men and women.
Pregnancy-Induced Hypertension: Exposure to PFAS during pregnancy has been linked to an increased risk of high blood pressure and preeclampsia.
Developmental Delays in Children: PFAS exposure in utero or during early childhood has been associated with potential developmental delays, lower birth weights, and other health effects.
Decreased Immune System Function
Reduced Ability to Fight Infections: PFAS may weaken the body’s immune response, making it harder to fight off infections and illnesses.
Decreased Vaccine Response: Studies have shown that PFAS exposure can reduce the body’s antibody response to certain vaccines, particularly in children.
Cancer Risks
Increased Risk of Kidney & Testicular Cancer: Some studies have found an association between PFOA exposure and an increased risk of kidney and testicular cancer.
Potential Increased Risk of Other Cancers: While the evidence is less clear, some research has suggested potential links between PFAS exposure and other types of cancer, such as prostate and breast cancer.
Thyroid Disease
PFAS exposure has been associated with thyroid dysfunction and disease. These chemicals can interfere with thyroid hormone production and metabolism, potentially leading to hypothyroidism or other thyroid problems.
How do PFAS enter the body and cause health problems?
So, how exactly do these PFAS chemicals in our homes make their way into our bodies and cause health issues? There are a few main routes of exposure to be aware of.
Ingestion: If you live in an area with PFAS-contaminated drinking water, you could be consuming these chemicals every time you take a sip. Certain foods, like fish caught in contaminated waters, meat and dairy from exposed animals, and vegetables grown in tainted soil, can also be sources of PFAS. Even food packaging, like greaseproof paper or microwave popcorn bags, can leach these chemicals into your meal.
Inhalation: Another way PFAS can enter your body is through inhalation of contaminated dust. These chemicals can accumulate in indoor dust, especially in spaces like fire stations or homes with a lot of PFAS-containing products.
Absorption: Lastly, dermal absorption from products is a potential route of exposure. Things like stain-resistant carpets, water-repellent clothing, and even some personal care products can allow PFAS to sneak in through your skin.
What are the environmental impacts of PFAS?
PFAS aren’t just a problem for our health – they’re also wreaking havoc on the environment. These chemicals have spread far and wide, leaving a trail of contamination in their wake.
One of the most concerning aspects of PFAS is its global distribution. They’ve been detected in air, water, soil, and wildlife all over the world, even in remote areas far from any sources of pollution.
This just goes to show how easily these chemicals can travel and stick around in the environment. They can linger in soil for decades, slowly leaching into groundwater over time. This means that even if we stop using PFAS today, we’ll still be dealing with the consequences for generations to come.
As if that wasn’t bad enough, PFAS are also working their way up the food chain. They bioaccumulate in animals, particularly in fish and other aquatic life. So, when we eat contaminated seafood or meat, we’re getting a concentrated dose of these chemicals.
Ways To Reduce Your PFAS Exposure
1. Purchasing PFAS-Free Products When Possible
- Look for products that are explicitly labeled as PFAS-free or PFC-free. These are your best bet for avoiding these chemicals.
- Support brands that are taking a stand. Some companies, like Patagonia and AXIOLOGY, have committed to phasing out PFAS in their products. Vote with your wallet and choose these brands when possible.
- Opt for alternative materials. When it comes to cookware, consider switching to cast iron, stainless steel, or ceramic options instead of non-stick pans.
2. Explore Water Filtration Options
- Invest in a reverse osmosis system. These systems are highly effective at removing PFAS from drinking water.
- Try activated carbon filters, while not as thorough as reverse osmosis, activated carbon filters can still reduce PFAS levels in your water.
- Consider ion exchange treatment. This method can be effective for certain types of PFAS, so it’s worth looking into.
3. Consider Lifestyle Changes To Minimize Exposure
- Choose fresh produce whenever possible, and avoid food that comes in plastic packaging and grease-resistant packaging.
- Ditch the plastic food storage containers and opt for glass or stainless steel instead.
- Say no to waterproof everything. Avoid waterproof fabrics and sprays, as these often contain PFAS. Look for alternatives that use natural fibers instead.
- Dust and vacuum regularly. PFAS can accumulate in household dust, so make sure to clean frequently to reduce your exposure.
- Skip the drive-thru. Minimize your consumption of fast food and takeout, as these often come in PFAS-laden packaging.
