Abstract

Provided are a method for producing an air filter medium in which the deterioration of the functions during bonding can be suppressed, an air filter medium, a filter pack, and an air filter unit. The method for producing an air filter medium includes a first step of preparing a porous membrane and an air-permeable membrane and a second step of bonding the porous membrane and the air-permeable membrane using a hot-melt adhesive in a molten state. In the second step, a temperature of the air-permeable membrane is lower than a temperature of the hot-melt adhesive in the molten state.
