Air funneling inkjet printhead

Some embodiments of the present invention provide a inkjet printhead having an internal ink reservoir, an ink via in fluid communication with the ink reservoir, a filter tower extending into the ink reservoir, and one or more walls at the base of the filter tower. In order to promote the movement of bubbles toward and into the ink via, the wall(s) at the base of the filter tower can converge and be inclined toward the ink via, and can have one or more protrusions thereon and/or recesses therein.
