Abstract:
The present invention provides an air-permeable filter capable of maintaining excellent air permeation performance without being clogged even in an environment involving exposure to an oil, oil mist, or ink. The present invention relates to an air-permeable filter including a porous membrane having a surface coated with an oil-repellent agent, the filter being characterized in that a sliding angle of 20 μl of hexadecane or pentadecane on the surface of the filter is 60° or less.

Claim (Index 3):
The air-permeable filter according to  claim 1 , wherein an air permeability value, as measured according to P 8117: 2009 (Gurley method) after an ATF oil or pentadecane is placed on the surface of the air-permeable filter and the air-permeable filter is kept inclined at 90\u00b0 for 1 minute to allow the ATF oil or pentadecane to fall freely, is less than 400% of an air permeability value as measured before the placement of the ATF oil or pentadecane.
