The Guppy Friend washing bag is designed to capture microplastics released when you wash synthetic clothes in the washing machine. These tiny plastic particles, which otherwise end up in our water and food chain, are captured in the laundry bag. Put your clothes in the laundry bag and run a wash on low speed to also save water and electricity. After washing you can remove the captured fibres from the hem and dispose of them in the non-recyclable waste. Don't worry! The washing effect will not be reduced, because water can penetrate through the pores unhindered. The bag also helps to extend the life of your clothes with less fiber loss!
