This is not a quantitative filter paper. According to the GE Lifesciences website (maker of Whatman filter paper), grade 598 filter paper is a quality filter paper. I have used them to filter functionalized silica with particle sizes from 60 to 250 µm and they have worked great. A pore size of 8-10 µm was excellent for our use. Lost a star due to false claim about quantitatively sorted filter paper.
