Guppyfriend Wash Bag


The GUPPYFRIEND Washing Bag is an effective, scientifically proven, and patented solution to stop microplastic pollution. Use it when washing clothing which contains synthetic fibers such as Polyester. No need to use it when washing natural fabrics such as Wool, Organic Cotton, Tencel and Linen. 

It reduces fibre shedding and protects our clothes.

It filters the microfibres that do break and doesn’t lose any fibres itself.

It’s a daily reminder to change our buying habits and washing rituals.
