ClearDevelopment and Efficiency Evaluation of Microplastic Removal Filter for Laundry Machines
Researchers developed a four-stage filter for laundry machines designed to capture microplastics released during washing. Over 50 tests, the filter achieved an average microplastic removal rate of 98.5%, along with 92% removal of chemical oxygen demand. The most common microplastics in laundry wastewater were polyethylene (57%), followed by PET and nylon, highlighting both the scale of laundry-related microplastic pollution and the effectiveness of filtration solutions.
Sustainable Filtering Systems to Reduce Microfiber Emissions from Textiles during Household Laundering
This study evaluated sustainable filtration systems for capturing microfibers released from synthetic textiles during household washing, assessing their efficiency in reducing the entry of these microplastic fibers into wastewater.
Evaluation of MiniPlast Filters for Microplastic Removal from Laundry Wastewater
Researchers evaluated MiniPlast in-washing machine filters for capturing synthetic microfibers released during laundry cycles, finding that the filters significantly reduced microplastic emissions in wastewater and could serve as a practical household intervention for reducing microfiber pollution.
Are we overestimate the contribution of microplastics from industrial laundry? Microplastic exploration in an industrial laundry: Quantification and elimination
Researchers investigated microplastic contributions from an industrial laundry in Sweden and tested two filtration technologies for removal. Both drum filtration and ultrafiltration achieved over 90% microplastic removal efficiency by mass, with polyester and smaller fragments being the most prevalent particles. However, a mass balance analysis revealed that local town wastewater contributed even more microplastics than the industrial laundry, suggesting that the contribution from industrial laundries may be overestimated.
Improvement of a microfiber filter for domestic washing machines
Researchers improved a microfiber filter designed for domestic washing machines to more effectively capture synthetic microfibers and microplastics released during laundry cycles, testing filter performance across different fabric types and washing conditions. The enhanced filter design achieved higher capture rates of microfibers compared to existing solutions, representing a practical household-level intervention to reduce microplastic emissions to wastewater.
Microplastics from textile origin – emission and reduction measures
This paper reviews the emission of fibrous microplastics from synthetic textiles during washing and their pathway through wastewater treatment plants into aquatic environments. It also summarizes available reduction measures such as laundry filters and fiber-releasing fabric design modifications.
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.
A Janus branch filter for washing machines: Simultaneous removal of microplastics and surfactants
Engineers developed a Janus-membrane branch filter for washing machines that simultaneously removes microplastics (capturing 78–89% of dreg by weight) and surfactants from laundry wastewater in a single step. This is a promising household-scale solution to one of the largest sources of microplastic release into waterways, since synthetic textiles shed enormous quantities of plastic fibers with every wash.
Removal of Microplastics from Laundry Wastewater Using Coagulation and Membrane Combination: A Laboratory-Scale Study
Researchers characterized microplastics in raw domestic laundry wastewater (9,000–11,000 particles/L, dominated by polyester fibers) and tested whether combining coagulation with ultrafiltration membrane filtration improved MP removal. The combined process significantly enhanced removal compared to coagulation alone, highlighting laundry wastewater as a major MP source amenable to treatment at scale.
Transport and retention of laundry microplastic fibres in slow sand filtration systems
Slow sand filtration — one of the most energy-efficient water treatment methods — was tested for its ability to remove laundry-derived microplastic fibers from washing machine effluent, with results showing 92–95% removal at the lowest flow rate tested. Fine sand filters slightly outperformed coarse sand, and the top layer of the filter did most of the work. Given that laundry wastewater is a major source of microplastic fiber pollution entering waterways, these results support slow sand filtration as a practical, low-cost add-on treatment to prevent fiber release.
Reuse of Water in Laundry Applications with Micro- and Ultrafiltration Ceramic Membrane
Microfiltration and ultrafiltration ceramic membranes were compared for the treatment of laundry wastewater containing microfibers, with both membranes achieving high microfiber removal while the ultrafiltration membrane provided better water quality for reuse. The study supports ceramic membrane filtration as an effective approach to capturing textile microplastics at the point of washing.
Capturing microfibers – marketed technologies reduce microfiber emissions from washing machines
Researchers tested three commercially available microfiber capture devices installed in washing machines and found that they significantly reduced the number and mass of microfibers released in laundry effluent. The results support the potential of in-machine filtration as a practical intervention to reduce microfiber pollution from domestic laundering.

A filtration system study in Galle, Sri Lanka investigated microfiber removal from hotel laundry wastewater, finding that synthetic microfibers from tourist accommodation laundry represent a significant and poorly managed pollution pathway to local aquatic ecosystems.
STEM Approach in Assessment of Microplastic Particles in Textile Wastewater
A multidisciplinary STEM approach was applied to characterize microplastic particles in both household laundry wastewater and industrial textile effluents. Microplastics were detected in significant quantities in both streams, with fiber shapes predominating. The study demonstrates that textile manufacturing and laundry are important but underregulated sources of microplastic pollution in wastewater.

The impact of a large textile laundry facility on the overall influx of microplastics and their removal in two wastewater treatment plants in the Netherlands
Researchers measured microplastic contributions from a large industrial textile laundry facility and found it accounted for 13% of the total microplastic load entering a nearby wastewater treatment plant. Encouragingly, the treatment plants removed over 99.8% of microplastics larger than 50 micrometers, suggesting that targeting major point-source emitters like laundries could be an efficient strategy for reducing plastic pollution.
