I bought a 5-stage RO (reverse osmosis) filter on Amazon. This review of my filter [1] says the RO stage filters down to .0001 microns.
"Stage four is a high quality .0001 micron reverse osmosis membrane. This is where most of the hazardous contaminants such as arsenic, lead, and barium are removed."
Does this mean I'm safe from microplastics?
