This Skills Workshop discusses the 4 key properties that must be considered when designers are selecting air filters - airflow, resistance, efficiency, and dust-holding capacity - as well as the concepts of size/penetration curves, particle adhesion, and electrostatic effects.
The concepts of filter resistance, filter efficiency (arrestance), filter penetration, and the factors that affect the dust-holding capacity of a filter are explained. A method for estimating the filter service life is also provided.
