There's a Surprisingly Simple Way to Remove Microplastics in Drinking Water

A 2024 study in China found boiling tap water with added micro- and nanoplastics, then filtering the residue, can remove up to 90% of particles.

The method worked better in hard water, where calcium carbonate helps trap the plastic particles as scale forms.

Researchers say this could offer a simple, low-cost household way to cut everyday exposure to plastic particles in drinking water.
