Organic fiber filters were developed for aerosol sampling. Organic fibers were produced by dispersing solutions of polystyrene in methylene chloride into a highvelocity air stream. A jet of the solution was broken up and drawn out into fibers from which the solvent evaporated. The dried fibers were collected to form a mat. Filter efficiency was 98% for solid aerosol particles of 0.01 to 1 mu in diameter at a face velocity of 14 cm/sec at atmospheric pressure. Filters were prepared in the size of 24 by 70 in. Alternate methods of producing the fibers and subsequent filter fabrication were investigated. (C.J.G.)
