Did you know all synthetic fabrics shed tiny pieces of plastic called microfibers in the wash? (It’s true. Even your favorite cozy fleece, swimwear, underwear, and, yep, Girlfriend leggings.) This filter attaches to your home washing machine to capture these fibers before they can enter water streams, keeping microfibers out of the oceans and away from the creatures that inhabit them. Let’s clean this place up. Installation parts sold separately. Please note filters will ship separately of clothing and may take up to 14 days.
