The main purpose of the Fighting Fibers Act of 2025 is to reduce microfiber pollution by requiring all new washing machines sold in the United States to include a microfiber filtration system. This legislation aims to protect the environment and public health by preventing tiny fibers from synthetic and natural textiles from entering waterways during the washing process. Key provisions of the Act mandate that starting January 1, 2030, all new washing machines must have a microfiber filtration system that meets specific standards.
