Cora Ball

Microfiber Laundry Ball


Inspired by the way coral filters the ocean, the Cora Ball was invented to reduce the amount of microfibers released from clothing while collecting any microfibers shed during the washing process. Peer reviewed studies have shown the Cora Ball to be effective at reducing up to 31% of microfibers that would otherwise flow out of washing machines.

Make an impact by using the Cora Ball to reduce microplastic pollution in our waterways and oceans!


  • 100% recycled plastic (Cora Ball has a take-back program, which grinds down old Cora Balls to add to new ones!)


Diameter: 4"


  • Toss the Cora Ball in with each load (one will do per washer). Works in both top loaders and front loaders.
  • Use Cora Ball when washing clothes made of synthetic materials like your fleece, outdoor gear, sportswear and swimwear
  • Microfibers can accumulate on your ball and tangle with hair and larger fibers. Grab the fuzz balls and dispose them in the trash.

Pro Tips

Microfibers are smaller than the eyes can see, so if you're not seeing fibers in the stalks, don't fret. Keep in mind that the ball is still working to reduce shedding from happening in the first place.

Use the Cora Ball together with the Guppyfriend Washing Bag as an individual-level solution for reducing microfiber and microplastic shedding.
