Measuring a micron rating through testing can be done through three methods: Nominal Micron Rating means that the filter can capture a given percentage of particles of the stated size. For example, a nominal micron rating of 10 microns at 95% means that the filter media retains 95% of the particles that are 10 microns and larger.
