Abstract
When aerosols of sub-micron particles pass through a fibrous filter, the fibres capture some of the particles. The relative importance of various possible mechanisms of capture were examined. The greatest effect in causing capture of particles was the vibratory component of air flow. If vibrations were superimposed on a steady flow, captures increased greatly. Under all conditions used, sub-micron fibres captured far more particles than seemed reasonable for their sizes compared with micron fibres. Possible reasons are discussed.
