Aunt Flow Period Products are PFAS-Free

September 17, 2025

No “forever chemicals,” no problem… Aunt Flow period products are PFAS-free! You deserve period care that’s made with you and the planet in mind. That’s why we’re committed to ensuring our products are crafted with clean, safe and non-toxic ingredients. Because what you put in your body matters.

What are “Forever Chemicals”?

PFAS (Per- and Polyfluoroalkyl Substances), also known as toxic “forever chemicals,” are a group of chemicals that repel water, dirt and oil. They are found in non-stick pans, waterproofing and some period products.

Why Does This Matter?

PFAS are commonly referred to as “forever chemicals” because they don’t break down easily. Instead, they stick around in the environment and build up in our bodies. They can impact hormones, immunity, fertility and cancer risk.

Luckily, you don’t have to worry about PFAS in Aunt Flow period products

founder + ceo

Hi! I’m Claire. I founded Aunt Flow after getting my period in public without the supplies needed.

At 18 years old, I dedicated my life to developing a solution to ensure businesses and schools could sustainably provide quality period products, for free, in bathrooms. Our products are made with organic cotton and we are constantly working to reduce our environmental impact! Since 2021, we've donated MILLIONS of period products to menstruators in need. I call this people helping people. PERIOD.®
