Abstract: An air filter medium reduces a decrease in collection efficiency in the case where a main collection layer and a pre-collection layer having a lower collection efficiency than the main collection layer are used. An air filter medium that collects dust in gas includes a main collection layer and a pre-collection layer that has a lower collection efficiency of NaCl particles having a particle size of 0.3 μm than the main collection layer, is disposed on an upstream side of an air flow with respect to the main collection layer, and has water repellency.

Abstract: An embossed air filter filtration medium has at least one porous film and a plurality of air-permeable support materials supporting the at least one porous film. The least one porous film includes a fibril-formable polytetrafluoroethylene, a non-fibril-forming and non-hot-melt-processable component, and a non-fibril-forming and hot-melt-processable component having a melting point below 320° C. Surfaces of both sides of the air filter filtration medium are formed by two air-permeable support materials of the air-permeable support materials. The air filter filtration medium has a plurality of embossed projections. The embossed air filter filtration medium may be part of a filter pack, which may be part of an air filter unit. The embossed air filter filtration medium is manufactured by laminating air-permeable support materials on the at least one porous film and embossing the air filter filtration medium to form the projections.
