Air filter medium, air filter pack, and air filter unit |
| abstract |
An air filter medium includes a first porous PTFE membrane and a second porous PTFE membrane. The air filter medium ( 10 ) has a first main surface and a second main surface, and the first porous PTFE membrane and the second porous PTFE membrane are arranged so that an air flow moving from the first main surface to the second main surface passes through the first porous PTFE membrane and subsequently through the second porous PTFE membrane. A thickness of the first porous PTFE membrane is in the range of 4 to 40 μm and a specific surface area of the first porous PTFE membrane is 0.5 m 2 /g or less. |
