WebWhat is the relationship between filter pressure drop and air flow rate? A filter’s pressure drop directly corresponds to a filter’s air flow rate. The higher the pressure drop the more restrictive the filter is to air flow. The lower the pressure drop the easier it is for air to flow through the filter.
