Zusammenfassung:A filter medium comprising a carrier layer (1) and a microfiber layer (2) applied thereon is characterized in that, with respect to the aim of providing a filter medium which has a relatively low pressure drop, and at the same time a good fraction separation rate and excellent dust storage capacity, the carrier layer (1) has first fibers, which are designed as endless bicomponent fibers and spunbonded fibers, and the microfiber layer (2) has second fibers, which are designed as endless melt-blown fibers.
