Researchers may have found an effective, green way to remove microplastics from our water using readily available plant materials. Their device was found to capture up to 99.9% of a wide variety of microplastics known to pose a health risk to humans.
RO removes up to 99% of microplastics. Ceramic water filters, water distillation, and nanofiltration also remove microplastics.
