A brief review is given of the derivation of a semi‐theoretical expression for the filtration efficiency of fibrous aerosol filters operated at low velocities. The correlation is compared with new data taken from the literature and is presented in a simplified form for design calculations. The existence of a minimum filtration efficiency is discussed and theory and data are compared.
