Test air filter media consisting of uniformly-packed fibers were prepared from water-dispersions of micro glass fibers with different diameters by hand making. Through the evaluation of collection performance of these filter media, it was found that the pressure drop of filter media prepared in this work was in good agreement with that of Fan Model Filters, showing that they were highly uniform in fiber packing. It was also experimentally shown that the filter media consisting of fibers with diameter smaller than 0.5 μm have a quality factor higher than those of coarser fibers. Furthermore, it was found that the difference between theoretically-predicted quality factors and the experimental ones is apt to be exaggerated when the particle penetration is high. These results are useful in designing the filter media for the energy-saving purpose, achieving low pressure drop and high collection efficiency at the same time.
