The Cora Ball is a human scale solution to microfibre pollution. This fantastic invention was inspired by ocean coral, and works to catch up to a third of microfibres per laundry load. The aim of this is to help prevent these fibres from entering the rivers, seas and oceans where they can be ingested by marine wildlife, or gradually form larger pieces of harmful microplastic over time.

The Cora Ball is made from 100% recycled and recyclable soft and stretchy plastic, and is designed to last for many years. 

Simple to use, the Cora Ball goes into your washing machine with the rest of your laundry and works to collect and trap micro plastic and synthetic fibres as it moves around inside your machine. In prime conditions, the Cora Ball collects microfibres that are too small for the eye to see, and over time a fuzz of microfibres can be formed and be disposed of in the right way, away from the ocean.

Important information - please read this before you purchase your Cora Ball:

The Cora Ball is suitable for all types of washing machines, including top loaders and washer dryers and is gentle on your clothes.

There are some items we don't recommend washing with the Cora Ball including lace, chunky knits and clothing with tassels or fraying ends. The Eco Shop will not take any responsibility for the clothing of Cora Ball users. 

Whilst we believe in this product and use it ourselves, we will not guarantee how much fuzz you will see within a specific timeframe of using the Cora Ball. The amount of microfibre collected will vary per household and depends on a number of things, including the type of clothes you are washing (some types of clothes will shed more microfibres than others), whether you use a front loader or top loader washing machine, how much water you use in the wash and at what temperature, the spin speed setting, whether you use powder or liquid, the type of water in your area, whether or not you have pets, and whether you use fabric conditioner. Just because fuzz is not seen by your eyes does not mean it is not being collected, or that microfibre is not being saved from the ocean. 

Cora Ball are working with some brilliant people to figure out where exactly that sweet spot is between catching and shedding fibres, which will help determine both how to maximize the use of the Cora Ball and how we can do the most to minimize the damaging effects of microfiber pollution.

Cora Ball have also been doing efficiency studies. There are also two independent groups doing this work. At this point it is known that the Cora Ball will collect up to 35% of the microfibers in each load of wash and eventually tangles them into what look like balls of fuzz that are a combination of fibers and often hair. When there is enough aggregated, you can simply clean the Cora Ball like you are cleaning a hairbrush by pulling the fibers off and throwing them in the garbage.

If you would like to take part in their study, here is a link to their survey. When Cora Ball have collated the data, they will reach back out to those who have taken part. Cora Ball are hoping to help customers get the most out of their Cora Ball and also contribute to the body of data about the best way to wash clothing, so that together we can minimize shedding (and thus, a slower working Cora Ball will be a good sign!).
