One of the key features of any filter is its pore size rating, which informs the user about the particle size it can effectively remove. However, there are certain aspects of the pore size rating that need to be carefully considered. Filter manufacturers typically specify pore size ratings as either Absolute or Nominal.
In general, a Nominal rating indicates the approximate particle size that the filter can capture, while an Absolute rating indicates the largest particle that can pass through the filter.
