Beschreibung
Zusammenfassung:	An air filter medium (10) includes a first porous PTFE membrane (1) and a second porous PTFE membrane (2). The air filter medium (10) has a first main surface (11) and a second main surface (12), and the first porous PTFE membrane (1) and the second porous PTFE membrane (12) are arranged so that an air flow moving from the first main surface (11) to the second main surface (12) passes through the first porous PTFE membrane (1) and subsequently through the second porous PTFE membrane (2). A contact angle of the first porous PTFE membrane (1) with water is in the range of 154° to 165°.
