The Guppyfriend Washing Bag is a scientifically proven at home solution for filtering out microplastics from synthetic clothing in your washing machine water. The microplastic fibers that break down during a wash are caught by the bag and easily removed, preventing them from entering our rivers and oceans!

The U.S. National Oceanic and Atmospheric Administration (NOAA) and the European Chemicals Agency defines synthetic microfibers or microplastics as any type of plastic less than 5 mm in length. These microfibers are commonly washed into our natural ecosystems when simply doing laundry.

The Guppyfriend has been scientifically proven 86% effective at reducing synthetic microfibers from shedding into our rivers and oceans and it protects your clothes. They will not harm the intact fibers in your clothes and help in the fight against microplastic pollution! 

The Guppyfriend Washing Bag was tested over a period of three years by scientific institutes, universities, representatives of the outdoor and textile industry, as well as retailers. These tests served as a basis for offering the Guppyfriend Washing Bag as a temporary solution against microplastic pollution. In particular, the Washing Bag was tested with the following scientific and independent institutes: German Textile Research Centre North-West, DTNW, Fraunhofer Institute UMSICHT, and the University of California at Santa Barbara as part of the Patagonia research program. On average the Guppyfriend Bag was determined to be 86% effective when washing completely synthetic clothing.

Plastic fibers that break off during washing are retained in the bag and can be easily removed by hand. It is best to dispose of the collected fibers in a closed container. This reduces the chance of the small and very light synthetic fibers being blown away during waste collection and ending up in the environment.

Polyamid 6.6 Untreated. This is a high-tech material and is particularly tough and resistant to alkalis. The fabric itself doesn't shed any microplastic fibers because it is made of monofilaments. These are more like stable sticks than threads, which are made from several fibers and are typically used for textiles. The binding tape consists of long staple fibres. Even if these should become detached from the bond, it is unlikely that they will break off.
The Guppyfriend Washing Bag works to prevent the shedding of microplastic fibers from entering our wastewater, rivers, lakes, oceans, and soils.

It is a great solution for laundering your clothing if they're not made from natural fibers, such as cotton, linen, hemp, etc.
This washing bag comes in a paper sleeve with a paper information packet in a cardboard box.
Remove zipper and recycle as a textile. The cardboard box and paper leaflet are recyclable in paper recycling.
