The purpose of this legislation, known as the Fighting Fibers Act of 2025, is to address environmental concerns related to microfiber pollution generated by washing machines. The act aims to require all new washing machines sold in the United States to include a microfiber filtration system. This is intended to reduce the release of microfibers into the environment, which can have harmful effects on ecosystems and human health. Key provisions of the act include the requirement that starting January 1, 2030, all new washing machines must have a microfiber filtration system.
