Questions & Answers
How much of the microfibres does the guppy bag collect?
Asked by: Anna P
There are a lot of variables to answering this question, please check out this explanation from our website > https://www.kathmandu.co.nz/summit-journal/sustainability-behind-the-label/guppyfriend
And here is some info from guppyfriends own testing:
The Guppyfriend washing bag reduces fiber loss during washing in two ways:
1. The Guppyfriend Washing Bag reduces the amount of breaking fibers significantly. The Fraunhofer Institute UMSICHT has confirmed an average amount of a) 79% for partly synthetic clothes, and b) 86% from completely synthetic textiles. The lifetime of the apparel is extended.
2. Fibrous residues and lints caused by washing are retained by the Guppyfriend Washing Bag and therefore do not pollute the wastewater. The determined fiber retention capacity in all test was above 90%, - mostly close to 100%. Nanoparticles, like production residues, often found on cheaper textiles can not be hold back by the Guppyfriend Washing Bag.

Much bigger than I expectedQuite expensive but I had voucher about to expire so half price. Really pleased with quality. Never thought about putting towels and bedding in wash bags so may have to get some more

It works!I've used the GuppyFriend bag for a few washes now and I can confirm that it works. The microfibres do build up in the seams, but are easy to clean out. At least now I have the confidence that I'm not contributing to the pollution of our waterways!

Collects microplasticsIt works really well and I use it for school uniforms etc. Need a tissue to wipe it clean and dispose of microplastics safely in the bin rather than waterways.
