Abstract: A cartridge filter includes a central core member having an axial dimension including a peripheral surface with a hollow interior, and a pervious filter material disposed about the peripheral surface of the core member. The filter material has a length substantially equal to the axial dimension of the core member and the core is an extruded non-woven tubular member having spaced-apart strand segments providing porous segments thereof. Axial ends of the core include solid band regions providing circumferentially continuous axial ends thereof, to thereby eliminate discrete, irregular edges that otherwise would be created by circumferentially spaced apart strand segments at each axial end of the core if the solid band regions were omitted.
