Fighting Fibers Act of 2024

S 4884, the Fighting Fibers Act of 2024, requires all new washing machines sold in the U.S. beginning January 1, 2030, to include a microfiber filtration system with a mesh size of 100 micrometers or smaller (or an equivalent standard), directly affecting manufacturers and retailers. It mandates clear consumer labeling about the filter's purpose and maintenance, such as "This washing machine contains a filter to capture microfibers. Check filter regularly and dispose of captured lint in a waste bin." The bill also directs the EPA to conduct a nationwide study on microfiber sources, health impacts, and environmental justice concerns, reporting to Congress within one year of enactment. These provisions aim to reduce microfiber pollution entering waterways from laundry.
