A wellbore screen includes a base pipe including a wall, an inner bore surface and an outer surface, an opening formed through the base pipe wall and a filter cartridge mounted in the opening. In one aspect, the wellbore screen includes an impermeable layer relative to the opening and the impermeable layer may be selected to be substantially impermeable when in a closed position in the opening to passage of fluids through the opening and, the impermeable layer is at least one of (i) selectively openable to permit fluid flow through the opening and (ii) selectively closeable when triggered to close the opening. In another aspect, the opening may include a tapering diameter from one end to the other and the filter cartridge may include an outer diameter formed to reversibly and substantially correspondingly taper relative to the opening to permit a taper lock fit in the opening.
