Multiple layer filter media

Filter media comprising:

• a first material comprising a first thermoplastic;
• a second filter material comprising a PTFE membrane having porosity;
• and
• a third material comprising a second thermoplastic;
• wherein in a first region of said filter media, at least portions of said first material are separately disposed in a first layer, at least portions of said second filter material are separately disposed in a second layer, and at least portions of said third material are separately disposed in a third layer;
• wherein said second layer is disposed between said first and third layers in said first region of said filter media;
• wherein in at least one second region of said filter media different from the first region, one of a portion of said first material or a portion of said third material fills at least a portion of the porosity of said second filter material to provide a bond for restricting relative movement between at least the first layer and the second layer or between at least the third layer and the second layer in the first region.
