The 3-Minute Guide to PFAS
Everything you need to know to get started, without the overwhelm.
Key takeaways
- PFAS are synthetic chemicals found in many everyday products
- They don't break down naturally, which is why they're called "forever chemicals"
- You can reduce exposure by making gradual product swaps
- Start with high-impact swaps: cookware, food storage, and personal care
What are PFAS?
PFAS (per- and polyfluoroalkyl substances) are a family of thousands of synthetic chemicals. They're valued for making products non-stick, waterproof, and stain-resistant. The problem? They're incredibly persistent and have been linked to health concerns.
Where are they found?
Common sources in your home include:
- Non-stick cookware (Teflon and similar coatings)
- Stain-resistant fabrics and carpets
- Waterproof clothing and outdoor gear
- Some food packaging (especially greaseproof wrappers)
- Certain cosmetics and personal care products
- Some dental floss
Why should I care?
PFAS have been associated with various health effects in studies, including thyroid issues, immune system effects, and reproductive concerns. While research is ongoing, many scientists and health organisations recommend reducing exposure where practical.
The good news
You don't need to panic or throw everything out. Many excellent PFAS-free alternatives exist, often at similar prices. Making gradual swaps as products wear out is a sensible, sustainable approach.
Your first 3 swaps
These are the highest-impact changes you can make. Start here:
Replace your everyday frying pan
Non-stick pans are one of the most common PFAS sources. Cast iron, stainless steel, or ceramic-coated pans are excellent alternatives.
Browse cookware recommendationsSwitch to glass or stainless steel food storage
Some plastic containers can contain PFAS, especially for hot foods. Glass and stainless steel are safer options.

Some dental floss contains PFAS for the "glide" effect. Natural fibre or PFAS-free options work just as well.
