Document Type and Number:

Japanese Patent JP3467779

Kind Code:

B2

Abstract:

A filter medium which has an average pore diameter of more than 0.5 mu m, a pressure loss of 2-50 mmH2O determined when air is permeated therethrough at a velocity of flow of 5.3 cm/sec, and a PF value of 18-12, which is calculated in accordance with the following equation on the basis of this pressure loss and a collection efficiency using DOP of a grain size of 0.10-0.12 mu m.
