What Are PFAS Chemicals—and How Can You Reduce Your Family’s Exposure?
PFAS chemicals have been making headlines lately, and for good reason. Known as “forever chemicals,” PFAS are found in everything from food packaging to waterproof jackets—and they don’t break down easily in the environment or in our bodies. These chemicals have been linked to serious health concerns, yet they continue to show up in our homes, products, and even our water. So what exactly are PFAS, and how can you protect your family?
Let’s break it down and give you some easy, actionable steps to cut down your exposure.
What Are PFAS?
PFAS (per- and polyfluoroalkyl substances) are a group of man-made chemicals used for their water-, grease-, and stain-resistant properties. They’ve been around since the 1940s and are commonly found in:
Nonstick cookware (like Teflon pans)
Water-resistant clothing
Stain-resistant carpets and upholstery
Fast food wrappers and microwave popcorn bags
Certain cosmetics and personal care products
Drinking water (especially near industrial sites or military bases)
According to the EPA and EWG, PFAS exposure has been linked to:
Hormone disruption
Weakened immune systems
Developmental issues in children
Certain cancers
Liver damage
Reduced vaccine effectiveness
Why PFAS Are Called “Forever Chemicals”
PFAS are nicknamed “forever chemicals” because they don’t naturally break down. Once released into the environment, they can linger in soil, water, and our bodies for decades. That means even low levels of exposure can build up over time—making it especially important to reduce contact wherever possible, particularly for children and pregnant women.
5 Actionable Steps to Reduce PFAS Exposure at Home
Reducing PFAS doesn’t require a complete lifestyle overhaul. Small swaps can go a long way. Here’s how to start:
1. Ditch Nonstick Cookware
Switch to cast iron, stainless steel, or ceramic cookware instead of nonstick pans, which are often coated with PFAS.
2. Check Your Water
PFAS contamination in drinking water is a growing concern. Invest in a water filter certified to remove PFAS, such as certain activated carbon or reverse osmosis systems.
3. Rethink Food Packaging
Limit packaged and fast food, especially items like microwave popcorn, takeout containers, and greasy wrappers that are often treated with PFAS.
4. Choose PFAS-Free Products
Look for personal care and household items labeled “PFAS-free” or “fluorine-free.” This includes makeup, waterproof clothing, stain-resistant furniture, and even dental floss.
Bonus tip: Use resources like EWG’s Skin Deep Database and Healthy Living app to screen products.
5. Avoid Stain-Resistant Treatments
Skip stain-resistant sprays on furniture, rugs, and clothing—these are often PFAS-based. Choose natural or untreated fabrics when possible.
The Takeaway: Awareness Is Power
PFAS are nearly everywhere—but with a little awareness, you can significantly reduce your family’s exposure. The goal isn’t perfection—it’s progress. Every small swap helps limit your risk and lowers your toxic load over time.
