Reducing microplastic pollution from washing machines.

HB 2212 requires new commercial and industrial washing machines sold in Washington to include microfiber filters that capture tiny plastic fibers (under 5mm) starting July 1, 2028, with existing machines needing filters by July 1, 2034. It mandates clear labeling on machines and regular filter maintenance to prevent microplastics - released in high numbers per laundry load - from entering waterways. The bill also allows for future residential machine requirements if other states adopt similar rules and costs stay below $70 per unit. Violations face civil penalties up to $10,000 per offense, enforced by the Department of Ecology. This targets a major pollution source linked to health and marine ecosystem risks.
