The transient behavior of aerosol filtration in model filters composed of several layers of wire screens was investigated experimentally. The collection efficiency of the filter expressed in terms of the single fiber efficiency was determined under a variety of conditions. The increase in the collection efficiency and pressure drop during the course of filtration was examined. An empirical correlation relating the increase of the collection efficiency as a function of the amount of deposition was established.
