Inspired by the way coral filters the ocean, NatGeo Explorer Rachael Z. Miller invented the Cora Ball. This device not only reduces the amount of microfibers shed by clothing but also catches what is shed during the laundering process.

Microfibers wreak havoc in the environment in spite of their microscopic size. To give you a sense of how small microfibers are, many microfibers need to accumulate before reaching the size of a grain of salt (see photo).

Even though captured microfibers might not be visible to the naked eye, you can trust that the Cora Ball is making a difference. It reduces up to 31% of microfibers that would otherwise flow out of washing machines and into our environment.

• The results of research published in the peer-reviewed journal Science of the Total Environment show the Cora Ball is effective at reducing 31% of the microfibers that would otherwise flow out of the washing machine after washing a load of laundry. This is an increase over the existing peer-reviewed study rate of 26% (McIllwraith, 2019).

This laundry ball works best for loads without straps, ties or loose threads that could snag or get tangled in the ball. It is 100% manufactured and assembled in the USA and will last you many years.

Make a positive impact by using the Cora Ball to reduce microfiber pollution in our oceans!
