Guppyfriend Washing Bag


The GUPPYFRIEND™ Washing Bag is a scientifically proven solution to avoid microfibers making their way from washing machines into our waterways. Synthetic materials give off microfibers (small plastic particles) when washed, which are too small to be retained in the sewage treatment plants and eventually end up in our rivers and oceans.

This washing bag is a practical and effective way to reduce plastic pollution. It is a self-cleaning fabric bag, made of Polyamide 6.6, which is a micro-filter material.

How it works

Simply put your synthetic garments into the GUPPYFRIEND™, close it up, place it into the washing machine and wash as usual. Hang-dry your clothes afterward and remove the released microfibers from hems inside of the bag. Dispose of it properly.

GUPPYFRIEND Waschbeutel ist klasse!

Ich nutze den Guppyfriend Waschbeutel nicht nur für meine synthetische Kleidung, sondern auch für empfindliche Kleidung aus Naturfasern um diese beim Waschen weniger zu strapazieren. Beides klappt wunderbar und die aufgefangenen Fasern lassen sich leicht entnehmen und entsorgen. Ich finde der Beutel ist ein tolles Utensil um seine Textilien zu schonen und gleichzeitig die Mikroplastikemissionen zu reduzieren.

Nice but should only be used with light fabrics

The bag itself is great, the quality is amazing. Only if you put in clothes, that tend to soak a little bit of water, the water also stayes after washing, leaving the clothes dripping wet and I have to wring them out in order to be able to hang them up for drying. So I decided to use it on the light synthetic garments like work out wear, which workes amazingly.
