Look how dense the material is that filters hydraulic oil down to 3 microns. It’s a very tightly packed cellulose material. Keep in mind that the oil oozes through from the center to the outside VERY slowly. It takes about an hour to get five gallons of hydraulic oil clean down to 3 microns. This science renders 95 masks USELESS against a nanometer virus.
