The GUPPYFRIEND® Washing Bag is the first pragmatic solution that prevents microplastic fibers from entering rivers and oceans through the washing of synthetic textiles. The broken fibers collect in the corners of the washing bag after washing and can be easily removed and disposed of.

How to use the Guppyfriend washing bag

Learn more about the Guppyfriend Washing Bag


A large part of our clothing contains synthetic materials. During washing, tiny plastic fibres break and enter rivers and oceans via the waste water and thus harm our environment. This is exactly where the Guppyfriend washing bag comes in. According to the Fraunhofer Institute UMSICHT, on average 86% fewer fibres of synthetic clothing break when washed with the washing bag. The fibres that do break collect in the corners of the washing bag after washing and can be easily removed and disposed of.

- It reduces fiber shedding and protects your clothes.
- It filters the few fibers that do break and doesn’t lose any fibers itself.
- It helps you remember not to dry your garments which protects their integrity and helps them last longer.
