A California bill is looking to make oceans cleaner by requiring new washing machines to filter microfibers from their emissions, a move designed to stop microfibers from falling off clothes and harming ecosystems—but the state has faced pushback from laundromats. AB 1628—which hasn’t yet been approved by the governor—would require all new residential and commercial washing machines sold on or before January 1, 2029, to include a microfiber filtration system to reduce the amount of microfibers that end up in oceans and freshwater, though older models without the filter can still be used if they were bought before the set date.
