Model proposed by the Friedlander, correlating the air filtration efficiency by impaction can be expressed as (where NSt is the Stokes number)

The weight of the dust captured by the absolute filter is compared to the weight of the dust fed into the air cleaner. The difference between them is the efficiency of the filter expressed as a percentage.
