Abstract : A parallel pleated HEPA filter has been developed to reduce the pressure drop across the Navy ND-C-1 filter by increasing the surface area in a minimal amount of space. The pressure drop was reduced by 594 percent due to an increase in the effective surface area of 677 percent. Spacing of the pleats was accomplished by dispensing adhesive and thread simultaneously on the surface of the filter media. This produced a spacing of 4.07 pleats per cm with a height of 0.91 cm.
