GUPPYFRIEND Microplastic Filter Washing Bag


Regular price HKD260.00
29 in stock

The Guppyfriend is a scientifically approved solution against microplastic pollution from washing.

  • Reduces fiber shredding and protects your clothes – tests confirmed that on average 86% less fibers break off when washing with a Guppyfriend.
  • Filters the few fibers that do break to prevent them from entering the water system
  • Doesn’t lose any fibers itself

Suitable for use with any clothing made from synthetic materials including polyester, nylon, acrylic. You can also use to wash clothing made from natural fibers in order to increase their lifespan.

Size: 50 x 74 cm

With each wash, plastic fibers from synthetic textiles can break off and make their way from washing machines into the water system, ultimately landing in oceans and rivers.

It is a predicament we are very aware of: whilst we are removing plastics from oceans and landfill through the use of post-consumer recycled yarns, we don't want our garments to create pollution issues through the shedding of microfibers.

This can be reduced by adjusting washing practices:

  • Wash on a cool wash (30 degrees)
  • Reduce spin cycle or skip this altogether
  • Wash for a shorter amount of time
  • Use less detergent
  • Don’t wash heavy items such as shoes or backpacks with clothes, as these will create more friction in the machine
  • Use a microfiber filter bag such as Guppyfriend to wash clothes
  1. Put synthetic textiles into the Guppyfriend Washing Bag.
  2. Wash your clothes as usual.
  3. Take out your wet textiles after washing.
  4. Remove the released microfibers from the upper corners inside the bag and dispose of them properly.
  • Wash the filled washing bag together with lose textiles.
  • Fill up to 2/3 – the textiles need to move inside the bag.
  • Wash cool at 30 degrees, but at a maximum temperature of 40 degrees/warm.
  • Always slide the zipper into the designated slot at the end.
  • The bag is self-cleaning, you just need to remove any collected microfibers. Don’t rinse under running water.

What is the Guppyfriend made from?
Apart from the zipper the bag is entirely made of Polyamide 6.6. The material is untreated, undyed, and does not contain any additives. Recycled material doesn´t work (yet) for this kind of high-tech mesh. But the washing bag is designed in such a way that it can easily be recycled with identical materials at the end of its lifecycle, just separate the cover with the zipper from the fabric to do so.

Does the Guppyfriend lose microfibers itself?
The mesh is made out of monofilaments, which are more like sticks than threads, and thus does not release fibers itself. On rare occasions, depending on the mechanical condition of your washing machine, the binding tape around the bag may release a few fibers. 

Does the Guppyfriend affect other garments in the washing machine?
No, you can do your laundry as you would without the washing bag. Continue to separate lights and darks.

Can Guppyfriend be used in the tumble dryer?
No. When there is no water in the bag, the material becomes statically charged and the microfibers will be able to move through the holes in the bag. We recommend hang drying your clothes wherever possible.
