Filter apparatus with vented core

A liquid filtering apparatus comprising:

• a bowl comprising an open end, a distal end opposite of the open end, and an interior that extends between the open end and the distal end;
• a manifold that is capable of sealingly engaging the open end of the bowl, the manifold comprising a fluid inlet and a fluid outlet;
• a cartridge assembly disposed at the interior, the cartridge assembly comprising a filter membrane, a cartridge assembly proximal end, and a cartridge assembly distal end, the cartridge assembly proximal end including a surface that is adapted to contact a surface of the manifold to form a cartridge assembly-manifold seal, and the cartridge assembly distal end including a surface that is adapted to contact an interior surface of the bowl to form a cartridge assembly-bowl seal at the interior;
• a core volume at a central inner side of the cartridge assembly;
• a housing volume of a housing at an outer side of the cartridge assembly between the cartridge assembly and the bowl of the housing, wherein the housing comprises a first core vent and a housing vent at the distal end of the bowl,
• wherein one or more of the cartridge assembly, the bowl, the first core vent and the housing vent are made of conductive polymer to provide electrostatic discharge (ESD) mitigation;
• and
• a second core vent extending from an exterior location through a distal end of the housing to the core volume to fluidly connect the core volume with the exterior location of the liquid filtering apparatus to allow venting of the core volume along a central axis of the cartridge apparatus to the exterior location, wherein the second core vent is made of conductive fluoropolymer to provide the ESD mitigation wherein the second core vent comprises a conductive material that electrically connects the core volume to electrical ground.
