Summary

Six devices designed to reduce microfiber release from laundry were tested, with an external filter (XFiltra) capturing about 78% of fibers and the Guppyfriend bag reducing release by about 54%. The study shows that current capture devices have meaningful but incomplete efficacy, and better solutions are needed across both product design and washing infrastructure.

Study Type Environmental

The washing of synthetic clothes is considered to be a substantial source of microplastic to the environment. Therefore, various devices have been designed to capture microfibres released from clothing during the washing cycle. In this study, we compared 6 different devices which varied from prototypes to commercially available products. These were designed to either be placed inside the drum during the washing cycle or fitted externally to filter the effluent wastewater discharge. The aim of this study was to examine the efficacy of these devices at mitigating microfibre release from clothing during washing or at capturing any microfibres released in the wastewater. When compared to the amount of microfibres entering the wastewater without any device (control), the XFiltra filter was the most successful device. This device captured microfibres reducing their release to wastewater by around 78%. The Guppyfriend bag was the second most successful device, reducing microfibre release to wastewater by around 54%; it appeared to mainly work by reducing microfibre shedding from the clothing during the washing cycle. Despite some potentially promising results it is important to recognise that fibres are also released when garments are worn in everyday use. Researchers and industry need to continue to collaborate to better understand the best intervention points to reduce microfibre shedding, by considering both product design and fibre capture.

Pore-size and polymer affect the ability of filters for washing-machines to reduce domestic emissions of fibres to sewage

This study tested whether washing machine filters could meaningfully reduce the emission of synthetic textile fibers into sewage. Results showed filter effectiveness varied significantly by pore size and fiber type, and current consumer filters did not eliminate fiber emissions, suggesting they are insufficient as a standalone solution for microplastic pollution from laundry.
