<abstract displayLabel="Summary">This paper compares experimental measurements of filter performance with predictions of aerosol collection by dust-mist respirators using the single fibre efficiency model and an empirical model developed by the authors. The former, a theoretically-based semi-empirical model, indicates that mechanical phenomena such a impaction, interception and diffusion are responsible for omly a fraction of the collection efficiency of dust-mist respirators, i.e. 30-70% depending of particle size</abstract>
