Cora Ball

What is
Cora Ball?

One innovative solution to microfiber pollution.

With every load of laundry, tens of thousands of microfibers sluff off of your clothes.

Despite the conception that only clothing made from polyester shed these evil microfibers, the reality is that ALL fabrics shed microfibers! However, to put this in perspective, a polyester shirt sheds up to 700,000 fibers per wash (source). Washing machines do nothing to stop these microfibers from going into the water stream and waste water treatment plants don't stop these fibers from reaching the ocean.

Want to learn more about ways to minimize your microfiber pollution? We teamed up with microfiber pollution scientist, Samantha Athey and wrote a blog post. Check it out here!

One easy way to limit your microfibers is by using a Cora Ball! According to a recent paper published out of University of Plymouth, The Cora Ball prevents 31% of the microfibers per load from washing downstream (Napper et. al., 2020)

What is Cora Ball?

Laundry Ball

The Cora Ball is a new kind of laundry ball. Inspired by the way coral filters the ocean, the Cora Ball collects our microfibers into fuzz we can see, so we can dispose of microfibers in the right way. Together, we keep these microfibers out of our waterways and our ocean. Just toss the Cora Ball into your washer and start protecting the ocean, its creatures and our human food web!

How Does it Work?

Toss the Cora Ball in your washing machine with your load of laundry. It swooshes around in the laundry and just like coral, allows water to flow, while picking up those little pieces of microfiber and catching them in its stalks. When you have tangles big enough to grab, you just move the stalks to the side and pinch the tangles to pull them out and throw them in the trash bin (we are working on finding a way to upcycle or recycle them, until then just do the same thing with this lint that you do with your dryer lint).

Things to Remember

The Cora Ball is safe to use in any washing machine, front loader, top loaders (with or without a center spindle), a hybrid, or whatever you have that washes your clothes. The Cora Ball works best with your everyday clothes. Please separate your delicates, knits, fine fabrics, anything with tassels, fraying threads or spaghetti straps. There is a chance that these clothes, fabrics, threads or straps work their way into the stalks and wrap, pull or worse.


But... it's made of plastic.

We thought the same thing! The Cora Ball is made of 100% recycled and 100% recyclable soft and stretchy plastic. The plastic will maintain its physical and chemical properties in the temperature extremes of both residential and commercial washers and dryers.

Is the Cora Ball recyclable?

Yes! Please do not put it in your blue bin. We hope you will use it long into the future, but if you are done with your Cora Ball, please contact Cora Ball.

Does it cause the clothes damage or make more microfibers?

According to Napper et. al. 2020, the Cora Ball helps reduce fiber shedding off of clothes, so the Cora Ball effectively protects your clothes helping them last longer while also protecting the ocean.

The items that do have potential to get past the rings and stuck in the stalks are: lace, crocheted/chunky knits, tassels or items with fraying ends - all of which could still be in the same wash, we recommend they are put in a wide mesh bag for delicates.
