摘要： The invention provides a filter pack of which the mass is not increased, and moreover, the effective filter medium area is not reduced, and of which the pressure drop is sufficiently low, and the strength is sufficiently high, and an air filter using this.A pleated air filter pack is configured in such a way that dot embossed projections are provided on front and rear surfaces of a filter medium made of a non-woven fabric, the filter medium is folded in zigzag shape along creases of pleats, and the opposing embossed projections are brought into contact with each other when the filter medium is folded, thus maintaining the intervals between the filter media.
