        I mean BBB filter threshold is anywhere from 2.3 to 50 nm depending on pressure. Even though microplastics can get down to 1nm that is like an outlier. So in a situation where virtually almost all of microplastics must be filtered out, how does one get such a huge percentage as 0.1%?

        It can’t help that so much of our food is packaged in plastic to keep water in or out.
