Who can use it?
Anyone can use the Cora Ball, in any washing machine; front loaders, top loaders with and without the center spindle, anywhere.
Where can you get a Cora Ball?
You can get a Cora Ball here online! Please sign up for our mailing list. Soon, you will be able to pick one up at your local green home store, at outdoor retailers (who sell a lot of fleece and technical clothing), with your laundry detergent, in new washing machines and more! Stay tuned! Here is a list of our first shops located across the globe!
Can I wash all of my clothes with it, even delicates?
We do NOT RECOMMEND that you wash anything with lace, tassels, chunky or wide-knit, crocheted sections, or fraying threads. The stalks on the Cora Ball might catch these delicate items and potentially cause damage. The good news is that these items are not contributing much microfiber, so leaving the Cora Ball out of the wash for your delicates is OK. Sometimes a bra or bikini strap will wrap around the Cora Ball; don’t worry, it is easy to unwind and unless the straps are made of lace, they will be fine (we’ve been testing with our own delicates for over a year and except for lace, have not had trouble).
How many Cora Balls should I use?
For most homes, one Cora Ball will do the job. For families, especially with a large washing machine, we recommend up to 3.
How much fiber does it collect?
According to a recent paper published out of University of Toronto, The Cora Ball catches 26% of the microfibers per load from washing downstream. The effectiveness depends on several factors including what items are in the load, wash settings, wash frequency and the presence of pet hair (which helps catch fibers)! We are constantly testing to learn how it works best so we can share with Cora Ball users.
Can I see the fibers it collects?
On the days you wash your heavier items, like fleece, sweatshirts, etc., you are likely to see the fibers stuck in the Cora Ball. Sometimes, after everyday clothing loads, you may not see much. It may be there accumulating and tangling up with hair and larger fibers, it’s just too small to see and you will be able to remove it when the tangles do get big enough to grab.
How does it catch tiny fibers?
The fibers tend to tangle together into fuzz balls that you can see and pick out of the Cora Ball. When we look at a microscope image from a pinch of what a Cora Ball collected from a 3-load test, we can see different colors and sizes all bunched together.
Do I have to clean it after every wash?
No, you do not need to clean the Cora Ball after every wash. We recommend, cleaning when it’s easy to clean - you’ll see big tangles of hair and fiber, then you can go for it.
How do you clean it?
When you have tangles big enough to grab, you just move the stalks to the side and pinch the tangles to pull them out. They come out easily.
Where do the fibers go?
The only option at the moment is to put the fibers in the trash, along with your dryer lint. It’s the same stuff. At this point, we cannot recycle laundry lint (from the washer or the dryer). But, Rozalia Project, and our partners, are working hard to figure this out. We look forward to the day when we can upcycle all of this material into new clothes or something durable and long lasting. Until that happens, the trash is better than straight to our public waterways.
What is the Cora Ball made of?
The Cora Ball is made of 100% recycled and 100% recyclable soft and stretchy plastic that 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 us.
How long will my Cora Ball last?
We have spec’d a material that is meant to last a long time and we hope the Cora Ball lasts for years and years of washing and catching microfibers. It was designed as a long-lasting and durable product, not for just a few uses.
Does it cause the clothes damage or make more microfibers?
We are driven by concern for plastic and man-processed fibers entering the marine environment, and for the longevity of your clothes, so we have 3 design strategies to keep the Cora Ball from making more microfibers themselves. Shape: the rings on the outside are smooth and round and that is what comes in contact with the clothes; Material: the material is extremely soft and stretchy - softer than some of your clothes! Finally, Motion: the Cora Ball moves with your clothes around the wash, not against them.
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.
Can I put the Cora Ball in the dryer?
Yes, you can. If you accidentally throw your Cora Ball in the dryer, not to fear! We chose a material that can withstand the heat and action of a dryer.
Why is international shipping so expensive?
We agree that shipping outside the US is incredibly expensive and wish we had more control over that. We have two suggestions: One is to see if you have a friend who might be interested in getting a Cora Ball too - to get the per Cora Ball shipping rate down. The other is to stand by - we've had a great reception about this product and are looking for international distributors. Once we have those relationships, the shipping will come way, way down for you, or even better, you will be able to purchase a Cora Ball at a shop near you in person.
Are there customs, taxes, VAT or other fees for international shipments?
There very well could be. We are eager to offer Cora Balls to ocean conscious global citizens everywhere, but every country has different customs laws. We declare the value that you paid on the customs forms and advise you to look into your country's policies prior to purchase.
What if my package was sent back to Cora Ball?
This can happen in the event that your delivery service deems the package unclaimed. The time period varies by location and country. We’ve had packages sent back from apartment building’s’ mailrooms, and because of nonpayment at customs offices in international location. In the event this happens, we are happy to reship your Cora Ball(s) to you. We will email you a link for re-shipping fees.
If you know you are going to be away when your Cora Ball is likely to arrive, we recommend making a plan for someone to collect your packages.
My tracking number says delivered, but I do not have a package. What do I do?
Unfortunately, this has happened. Our experience is that it was either delivered to the wrong location or was stolen.
If the post office has delivered your package, but it has gone missing, please try the following:
- You can first file a claim with the shipping company if you selected insured priority mail
- Follow up with the credit card company you used to purchase your Cora Ball. Often, they replace the goods you purchased in the event of theft or loss.
Has there been any independent testing of the Cora Ball?
Yes! There's an independent test investigating the effectiveness of the Cora Ball out of Dr. Chelsea Rochman’s lab at the University of Toronto. It was lead-authored by Hayley K. McIlwraith and is now published in the peer-reviewed journal, Marine Pollution Bulletin.
The results: the Cora Ball is an effective solution for microfiber pollution! In their words, “These results suggest that these two technologies added to washing machines [Cora Ball and the Lint Luv-R] could be an effective way to reduce microfiber emissions to the environment. While further investigations are needed to understand the relative contributions of microfibers from other textile products and their pathways to the environment, we know that textiles laundered in washing machines are one source of microfibers and that effective mitigation tools currently exist.” The paper itself is behind a paywall, but Forbes also covered it with a great summary here.
