Guppy Friend Bag

  • $48.50

Product Description

The Guppyfriend Washing Bag is the most effective hands-on solution against microplastic pollution from washing. The Guppyfriend washing bag is the first pragmatic solution that prevents microplastic fibres from entering rivers and oceans through the washing of synthetic textiles. The broken fibres collect in the corners of the washing bag after washing and can be easily removed and disposed of.


  1. It reduces fibre shedding and protects your clothes
  2. It filters the few fibres that do break
  3. It’s a daily reminder to change our buying habits and washing rituals


Product details

  • size: 29.1 x 19.7 in (74 x 50 cm)
  • material: polyamid 6.6 untreated


How to Use 

  1. Put synthetic textiles into the Guppyfriend washing bag
  2. Close the Guppyfriend washing bag and put it in the washing machine. Add other, non-synthetic, textiles and wash as usual.
  3. Take the textiles from the Guppyfriend washing bag while they're still wet.
  4. Remove the collected fibres from the inside of the filter fabric by hand and dispose of them in the residual waste. 


Instructions for use:

  • Fill to about ⅔ full so that the textiles can easily move around in the bag
  • Add other (non-synthetic) garments to the machine or a second filled Guppyfriend to avoid imbalance
  • Wash cold or warm with 104F / 40°c maximum
  • Use liquid and natural detergents without synthetics
  • Remove coarse dirt and pet hair before washing
  • Close the zipper all the way


Please do not:

  • Rinse under running water. The collected microplastic fibers would be washed into the environment
  • Wash with sharp-edged objects to avoid damaging the material
  • Iron your bag. This can damage the filter material (the crumpled surface is not a problem)
  • Use in the tumble dryer. It can damage the material and broken fibers can get out of the bag
  • Hang/dry in direct sunlight to avoid damaging the materials
