Hello Dani,
Thank you for being an Ocean Protector! Great job loading your washer 3/4 to full! This is known to reduce the amount of microfiber produced off your clothes in the first place, helping them last longer and causes less pollution.
Cora Ball is optimized to prevent microfiber pollution by preventing fiber fragmentation off our clothes and also to tangle and collect fiber. Cora Ball may tangle long human and pet hair, but that is not the primary purpose. You can read more about how Cora Ball works to prevent microfiber pollution here: https://bit.ly/36EaktH
We hope you will continue to use your Cora Ball with optimism and confidence, as we believe every amount of microfiber that is diverted from going downstream is a triumph - whether that is the invisible benefit of your clothes shedding less or because the Cora Ball is collecting those fibers that do break off. Thank you for taking part in this collective action with tens of thousands of others.
