A filter system for filtering a fluid containing particles includes a porous substrate. The porous substrate is made of a porous ceramic material. A filtering material is connected to the porous ceramic substrate. The filtering material includes nanofibers. The fluid travels through the porous ceramic substrate and travels through the filtering material wherein the particles are captured in the porous ceramic substrate and in the filtering material.
