Meet The Cora Ball
The World’s First Microfiber Catching Laundry Ball!
Protect the ocean environment with this easy-to-use laundry ball that catches microfibers shedding off our clothes in the washer.

We Are Eating Our Clothes!
Rachel Miller (Cora Ball founder) noticed a problem. Every time we do laundry, our clothes shed tiny, unseen microfibers (including plastic), which go down the drains of our washing machines and into our waterways. That’s not great for the animals living in those waters or for us!

How the Cora Ball Works

Most washing machines don’t have filters that can catch fibers too small for the human eye to see AND allow water flow. That’s where the Cora Ball comes in.

Cora swooshes around in laundry and just like coral, allows water to flow, while picking up those little pieces of microfiber and catching them in her stalks. An independent study investigating the effectiveness of the Cora Ball done at the University of Toronto showed that the Cora Ball catches 26% of the microfibers from flowing down the drain!

The Microfiber Problem

The single biggest pollution problem facing our ocean is microfiber: trillions of pieces of tiny fibers flowing into the ocean–every time we use our washing machines! One fleece jacket could shed up to 250,000 pieces per garment wash. The worst part? We are ALL contributing to this problem.

But we can all also be part of the solution!

If 10% of U.S. households use a Cora Ball, we can keep the plastic equivalent of over 30 million water bottles from washing into our public waterways every year. That’s enough water bottles to reach from New York City to London!


  • One Cora Ball is usually enough for most households. For large families with large washing machines, you can use up to three.
  • You don’t need to clean the Cora Ball after every wash. You’ll be able to see tangles and then it’s time to clean.
  • Once you’ve cleaned up your tangles, simply throw the remnants in the trash.
  • The Cora Ball is made from 100% recycled soft and stretchy plastic and will last for years and years.
  • The Cora Ball is $40
